Mert spine - how is the diagnostic procedure, preparation for the study and contraindications
Modern medicine uses MRI for the spine as a highly informative procedure for examining patients with a pathology of bone and soft tissues of the body or suspected of their presence.
The method of layer-by-layer imaging of the structure of surveyed objects is used not only to diagnose existing diseases, but also to determine the stage of their formation and development.
In addition to the accuracy of diagnosis, MRI excludes damage to the body of the patients being examined.
What is MRI of the spine?
The method of magnetic resonance tomography is based on the interaction of a strong magnetic field, artificially created by the device tomograph, and atomic nuclei of hydrogen, located in the human body.
The speed at which the response to an external stimulus is received depends on the saturation of the organism with hydrogen atoms and the energy released by them.
In addition to a powerful magnet, the scanner includes a gradient coil that determines the location of the signal in space and allows you to make an image.
The accuracy of diagnosing diseases with MRI depends on the competence of the doctor.
Deciphering the obtained images of the spine provides an opportunity not just to see the surface bone tissue of the ridge, but also to analyze the state of the spinal cord, determine its thickness at all sites.
If there is a suspicion of a neoplasm in the brain or spinal cord, the MRI procedure involves intravenous administration of a contrast medium.Such a technique facilitates structural analysis of the diagnosed vertebral zone.
The doctor can prescribe MRI for patients with spine and joint diseases or those who have previously undergone MRI diagnostics to track the results of the treatment. In addition, the CT scan is indicated if there are suspicions of the presence of the following pathologies:
- defeat of the spinal cord (ischemic, tumor, inflammatory);
- osteochondrosis of the cervical spine;
- osteoporosis;
- intervertebral hernia;
- violation of the patency of blood vessels;
- displacement of the vertebrae of the lumbar spine (spondylolisthesis).
The need for magnetic resonance imaging arises from complaints of severe headaches, numbness in the limbs after trauma.
Even if the pain did not appear immediately after a trauma or accident, it is recommended to perform an MRI procedure diagnostics for the investigation of possible pathogenic changes in the spine, the symptoms of which may appear later some years.
Benefits
Magnetic resonance imaging is a breakthrough in the discovery of methods for studying the structure of the skeleton and human organs. The invention of a tomograph has provided world medicine with the possibilities:
- receive clear images of the spinal column in all projections;
- detect the presence of a tumor at an early stage;
- to reveal pathogenic changes in bone tissue;
- to give timely recommendations on prevention of development of pathologies of the spine;
- conduct spine and joint studies without the use of ionizing radiation.
With the help of the magnetic resonance method, it became possible to visualize the condition of the vertebrae and intervertebral discs.
The difference between MRI and other diagnostic methods lies in the possibility of detecting prolapse (the initial stage formation of the intervertebral hernia), which simplifies the process of preventing the transition of the disease into a chronic form. Before the discovery of MRI, such problems were determined at the stage of manifest manifestation of the disease.
The price of the MRI procedure is fully justified because after diagnosis with magnetic resonance imaging, there is no need for other types of examination.
High information value of the obtained results helps to avoid the cost of additional methods.
According to the reviews of patients who have been examined with MRI, diagnostic procedures, the price of which is lower, does not always justify the received cost savings.
How often can I do
The negative impact of MRI on the spine during the ongoing pilot studies and for the entire practice of this type of diagnosis is not revealed.This procedure is harmless even for an infant.
The inconvenience can be only in the need to remain stationary during the whole session of resonance tomography. Conduct MRI, if necessary, at least every day.
There are no restrictions on the part of doctors on the time and frequency of diagnosis.
Preparation
Conducting a magnetic resonance examination does not require special preparation. Clothes should be free, without metal buttons or fasteners.
Before the examination, it is necessary to remove all ornaments, lay out of pockets objects that may contain metal particles. Dentures, if they are removable, also have to be left outside the procedural.
.Patients with psychopathological symptoms and small children may be offered light sedation medications before MRI.
.Preparation for MRI of the lumbosacral spine, if it is carried out with the introduction of contrast, additionally involves the surrender of a blood test to prevent the possibility of an allergic reaction to preparations. Due to the fact that the basis of the contrast is gadolinium metal, the possibility of manifesting undesirable reactions is minimized, but it is not excluded.
How do
The procedure for magnetic resonance imaging of the spine is in a specially equipped room.
The standard tomograph is a large cylindrical tube, inside which is a mobile table.
Before a diagnostic test, it is necessary to undress only if the patient's clothing contains non-removable metal objects or is too tight to the body.
Immediately before the procedure of diagnosis, the patient, taking off his shoes, lies down on the table. The limbs are fixed using special straps to ensure immobility during the MRI procedure.
Depending on the diagnosed part of the spine, the mobile surface moves to the inside of the pipe to a certain level.The doctor always remains in touch with the patient being examined by means of a microphone installed in the device.
During the session, discomfort can arise only because of sharp sounds, whose purpose is to cause the necessary resonance.
How much time is MRI done
Tomography of the spine departments without the introduction of contrast medium lasts from 20 to 45 minutes. The need for the drug increases the duration of the examination, and it is from 30 minutes to 1 hour.
The results of the performed procedure in the form of pictures and disks recorded in the DICOM format are issued in hands for half an hour.
The doctor who performed the diagnosis of the spine provides his diagnostic conclusion in hard copy, certified with a signature and stamp.
What MRI shows
The doctor who gave the referral for the examination can decipher the images obtained after the MRI of the back.
When the final diagnosis is approved, the opinion of a specialist who performs a tomography and printout of images of the spine departments is taken into consideration.
A detailed analysis of photographs can show:
- condition of bone tissue of vertebral discs;
- the presence of inflammatory processes in soft tissues;
- congenital or acquired anomalies in the structure of the vertebrae;
- clamping of nerve endings;
- spinal cord injury.
When contacting a diagnostic center without referral, it is possible to order a service for deciphering the images obtained by spine examination on a paid basis.
Experts of the consulting center will render the qualified help if to give them results of MRI diagnostics on a removable carrier and in a format of the printed out image.
Do self-diagnosis is not desirable.
Contraindications
Conducting MRI for the spine is harmless, but, given the use of strong magnetic fields during the procedure, there are several contraindications for the diagnosis in this way. These include:
- presence of metal implants or prostheses;
- presence of tattoos on the patient's body;
- overweight (weight over 120 kg);
- panic fear of enclosed spaces.
Women need to report before the spinal diagnosis procedure about a possible pregnancy because the effect of the magnetic resonance field on fetal development has not been fully studied.
During lactation it is better to consult a doctor about the possibility of diagnosing this way. Magnetic resonance imaging of the spine is not performed in case of urgent diagnosis and acute pain syndrome.
Obstruction for CT imaging with the introduction of a contrast agent may be an allergy.
How much is
Patients suffering from back pain of unknown etymology often turn to doctors to find out where to make an MRI of the lumbosacral spine.
In Moscow, an MRI procedure can be performed cheaply and qualitatively in specialized clinics. The cost of MRI of the spine ranges from 1800 to 17 000 rubles.
The price of services depends on the area of the back and the need to introduce contrast agents, and sometimes on the time of the day of diagnosis.
Turning to the services of specialists offering a cheaper option for diagnosis of the spine with MRI, you should check the availability certificate of the doctor, the facility's license to provide medical services and a valid license for equipment used for surveys.Often, low prices conceal the lack of quality, which is unacceptable in matters of health.
: How MRI of the spine is done

Mert spine, how is the procedure?
Back pain is quite common in people of all ages. Sometimes the problems of the disease can be the most serious.
The most effective method for identifying violations and problems with the spine is its diagnosis with the help of special modern medical equipment and equipment.
At present, it can be done with the help of an MRI or by carrying out a computer tomography, taking pictures.
MRI of the spine - a modern type of diagnosis
The essence of MRI of the spine
MRI or magnetic resonance imaging is a procedure that allows using a powerful magnetic field, computer and high radio frequency impulses get a photo with data on problems with the spine in patient.
How is the MRI of the spine
Thanks to the latest equipment, specialists receive images where there is all the evidence of pathology in various planes and can follow how the disease progresses.
MRI allows you to obtain data on the state of the spinal cord, cervical, lumbar, thoracic and sacral departments of the spine, surrounding soft tissues, as well as to reveal various kinds of pathology: tumors, inflammation, hernia.
When do MRI of the spine?
Such a study can be carried out only after the appointment of a doctor. Basically, the MRI of the spine is done to those who have:
- benign and malignant tumors;
- congenital anomalies;
- cardiovascular diseases of the spinal cord;
- inflammatory diseases of the spine and adjacent tissues;
- myelopathy;
- multiple sclerosis;
- syringomyelia;
- osteochondrosis;
- hernia;
- there was a trauma of the spine or spinal cord;
- it is necessary to check the spine after the operation.
How does the MRI of the spine?
The procedure of MRI is quite simple and does not carry any danger. But you can not always go for free. To pass it, the patient is placed on a special table, where he must lie motionless for about fifteen to twenty minutes.
How do MRIs work?
Diagnosis allows you to get a photo, which will show the investigated areas and organs of the body. Due to this, it is possible to understand the cause of the ailment, to identify the problem, to assess the degree of danger, etc.
Such research is conducted in open and closed devices.
Open devices are used mainly to study the organs of those people who are afraid of confined spaces, seriously ill patients, and also for diagnosing small children. All other patients are placed in closed devices to obtain the necessary information.
Open device for MRI
When can you not carry out MRI of the spine?
This procedure is contraindicated to people:
- with mental disorders;
- with the presence of installed pacemakers, metal implants, prostheses;
- patients with convulsions;
- with an increased risk of epileptic seizures;
- pregnant (in the first trimester).
Closed device for MRI
Where it is possible to make MRT a backbone?
The procedure of MRI is carried out in many medical institutions. In some cases, it is possible to conduct this study free of charge, taking into account the indications. Otherwise, the diagnosis is paid on a fee basis.
After visiting the attending physician, having received a direction for tomography, you can choose a clinic yourself, which will correspond patient requirements: remoteness from home, the presence of an open or closed device, the power of the magnetic field, the cost of services provided etc.
How much does an MRI of the spine cost?
The cost of diagnosis, magnetic resonance imaging or computed tomography of the spine, sufficiently accessible to a person with average earnings.
It all depends on what kind of clinic the person chooses, which part of the spine will be diagnosed, and possibly a comprehensive examination of the entire spine.
In Moscow, on average, such a service costs from 5000 to 7500 rubles for CT and 4000 to 6000 rubles for an MRI of one of the departments of the spine and about 1, 00 rubles for the body as a whole.
Computed tomography of the spine
In some cases, instead of MRI, patients undergo a CT scan of the spine, which is a survey internal organs of a person with the help of special X-ray equipment and computer techniques. Computed tomography allows you to obtain a photo of the internal parts of the patient's body and identify violations in the spine.
Modern devices for diagnosis with MRI
Basically, the computer tomography of the spine is performed after the operation, when injuries are received, detection of tumors, diagnosis of the cause of back pain, assessment of congenital anomalies, trauma, density measurement bone tissue. The resulting photo shows problems, neoplasms and other disorders in the structure of the spine and surrounding tissues. The study can also be done free of charge, but for this you need to have certain indications for conducting it.
To pass the CT of the spine, you need to remove all metal objects, as well as jewelry, which can prevent competently and effectively conduct research.
.If metal objects can not be removed for some reason, for example, in the presence of a pacemaker or implants, the procedure can be canceled or postponed for some reason.
.It is also important to know if the patient has an allergy to contrast agents so that at the time of the diagnosis there is no allergic reaction to the drug administered.
Computer tomography is usually done fairly quickly - it takes about half an hour, and absolutely painless.
However, in people suffering from claustrophobia, or in young children, equipment can cause anxiety repelling, negative reaction.
During the research can not move, otherwise the photos may turn out to be substandard, the image on them will be blurred, and sometimes this leads to even false data and the diagnosis gives false indications.
In Moscow, a computer tomography scan of the spine is not difficult. Many medical institutions provide such services to clients. However, as a rule, this research is still not free.

Mert spine, how is the procedure, what are its features
We can say with confidence that the spine is the core and support of the whole organism. If any of his department has a problem, this affects the work of other bodies and systems.
To determine the problem with the greatest accuracy, magnetic resonance imaging is performed.
Having received such a direction, patients are interested in: why do MRI of the spine, how is the procedure going and is it necessary to prepare for it ?:
.What abnormalities can be detected with MRI of the spine? The spinal column is a highly informative technique for identifying various abnormalities and pathologies. Its huge plus is the ability to identify the disease at the earliest stages.
.Such an outcome is not capable of showing ultrasound or X-rays. MRI of the spine is indicated for severe pain syndrome, trauma, numbness of the upper or lower extremities, birth defects or for the prevention.
Due to such diagnostics, the following are revealed:
- inflammatory process in any department
- nerve entrapment
- intervertebral hernias, protrusions
- presence of tumors
- cystic formations
- degenerative changes in cartilage or other tissues
- intervertebral disc shift
Problems with the back experiencing a huge number of people. For treatment to be effective, accurate diagnosis is necessary. To back pain in the past, you will first have to determine their cause.
Whether there is a procedure for contraindications MRT, like any medical procedure, has certain limitations. And although there are not so many, it is better to get acquainted with them in advance. This should be discussed with a doctor.
Contraindications for the procedure are as follows:
- The presence of a pacemaker that can not be removed
- residual metal fragments in the body after bullet wounds
- severe forms of claustrophobia (possibly passing through when taking sleeping pills)
- the presence of implants from metal (may come into disrepair)
- pregnancy (especially the first trimester)
- acute injuries
Sometimes the patient's excessive weight is a contraindication. Some phones have limitations. However, many installations are designed for a mass of up to 180 kg. When passing an MRI it is worth considering that all the time of diagnosis a person should be immovable.
If the patient is excitable, the doctor can recommend a preliminary sedative. The procedure is not carried out in emergency cases, when the decision must be taken very quickly because of the length of the procedure.
Preparation for diagnosis The basis of magnetic resonance imaging is the principle of exposure to a magnetic field. Therefore, it is logical to exclude all objects containing metal before the inspection.
Also, do not go to the procedure with phones, medical devices, credit cards (contain a chip) and any magnetic media. It is necessary to remove all rings, chains, watches, bracelets and belts. Carefully check the pockets before starting. This is what concerns technical issues.
Those who have recently tattooed should know that in its place may appear irritation. Where a medical adhesive is stuck, the likelihood of a burn on the skin is high. To relieve fear and stress, doctors sometimes recommend the use of sedatives before the procedure.
People with complex mental disorders or severe forms of claustrophobia are often immersed in sleep with a sleeping pill. In the rest, no special preparation is required to pass the MRI of the spine. There are no restrictions on nutrition.
How to practice the examination It is necessary to be prepared for the fact that the patient is placed in an elongated tunnel for a fairly long period. Most often the process takes about 20 minutes, but it happens that it takes up to, hours of time. The procedure is absolutely safe and painless.
A man is put on a medical table, fixing straps on his chest, arms and head. This is necessary for the body to be motionless, and the image clear. The more modern the installation of an MRI, the more spacious it is.
Therefore, the newest devices practically do not cause fear of confined space. For the best health in the pipe built-in fans. Each patient has the opportunity to communicate with the employee through a communication device.
.If suddenly you feel ill, dizziness, nausea or pain of any kind will begin, you should definitely inform the medical center employee about this. The apparatus is rather noisy, the subject is continually hearing clicking sounds. This need not be feared.
.For better comfort, patients are given soundproof headphones. No pain should arise. The results with all the descriptions are issued on hand a few hours after the study. With the information received you can go to the doctor in charge.
Tomography of different parts of the spine Depending on the complaints and diagnosis, the patient may be shown the study of the entire spine, or some of its departments. Cervical department Very often, MRT of the cervical department is prescribed.
How is the procedure performed and to whom is it shown? It turns out that hernia and osteophytes in this area do not always have severe symptoms. And similar pathologies are detected by means of tomography. Pain syndrome may not be.
Problems with the neck affect your health, causing frequent headaches. With the help of MRI of the cervical department, tumors, dislocations, cracks, hernias, protrusions are diagnosed. Identify the stenosis of the vertebral canal, the displacement of the vertebrae. Check the adequacy of the work not only of the neck, but also of the brain.
The algorithm of the procedure is similar to the tomography of other areas. Lumbar disease The diseases of the lumbar part of the doctors are called the most common. It is in this part that patients experience pain and discomfort. A person with a similar problem wonders: MRI of the lumbar spine - how does the procedure go? The development of such an examination differs little from other types of tomography. Some clinics give out one-time clothes for the procedure. To feel comfortable and more confident experts recommend going to the examination, accompanied by a loved one. It should be remembered that in the tunnel you need to maintain stillness for the clarity of the picture. Thanks to MRI, the following deviations are diagnosed and excluded:
- stenoses of the canal of the spine
- tumor formation
- hernia, trauma, intervertebral disc shifts
- osteochondrosis
- abnormal changes in the lumbosacral region
- sacralization of intervertebral bodies
The ptology department of this department is much less common. However, even here there can be unfavorable changes. MRI of the thoracic region is often required for people with congenital defects in the structure of the vertebrae.
There are acquired problems due to injuries, falls or accidents. Only the method of magnetic resonance tomography makes it possible to identify in the thoracic department such pathologies as multiple sclerosis or encephalomyelitis.
The procedure determines the abnormal vascular communication of the spinal cord. Assign with various injuries and fractures in the department. And, of course, diagnose osteochondrosis, protrusions and tumors of various types.
Coccyx and sacroiliac joints Only MRT allows you to undergo reliable diagnosis of this area. Especially attractive is the method of high safety and lack of physical intervention in the body.
Indications for tomography of the coccyx and sacroiliac joints: equal, fall of bone damage unclear cause of inflammation of the tumors of the spinal column of the spine - an effective method research.
Allows you to study a specific area or, if necessary, all departments. Cost of the serviceMagnetoronance tomography is a rather expensive procedure. The price of one MRT installation is at least 200 thousand. dollars. This explains the high cost of research.
.Diagnosis is carried out with complaints or for the purpose of prevention. As you know, the disease is better to warn than to treat for a long time. Therefore, do not save on your health. The spine is one of the foundations of the human body.
.The prices for the procedure vary depending on the clinic and the region. The larger the study area, the higher the cost. MRI of the neck starts from 50-100 dollars. While the tomography of the entire spine will cost in the amount of 200-300 dollars.
MRI does not have any radiation load, like an X-ray. You can conduct it repeatedly without any fear. If you are shown a MRI of the spine, do not be afraid. This is an important step towards health. The procedure allows you to get the most accurate diagnosis and maximum information. With all the recommendations, the study does not cause any inconvenience to the patient.

What MRI of the spine shows: preparation for examination, contraindications and price
Magnetic resonance imaging of the spine is a very accurate and informative diagnostic procedure.
It is practically safe for human health, and therefore actively used in medicine.
In this study, the patient is not exposed to radiation, since the principle of the scanner is based on nuclear magnetic resonance.
Mert spine - what is it and why it needs to pass
MRI is included in the category of non-invasive procedures,It is used to diagnose and select a treatment regimen for various diseases and spinal injuries.
At the heart of the MRI are frequency radio waves, as well as a magnetic field.
This procedure allows you to obtain accurate images of the spine by computer processing.
Photographs of the spine, obtained by MRI examination
The results obtained with MRI can be assessed on a computer screen or saved electronically. Also they are printed on film. The procedure does not require ionizing radiation.
What the diagnostics shows
There are a number of indications for performing MRI. In particular, the procedure is used for the following purposes:
- Evaluation of vertebral anatomy, detection of deformational changes.
- Identification of pathologies of intervertebral joints.
- Definition of congenital anomalies of the vertebrae or spinal cord.
- Evaluation of the results of the operation - the presence of an infectious infection, scarring.
- Diagnosis of compression of the spinal cord and nerve endings.
- Determination of the condition of the disc - the detection of a hernia, protrusion, form disturbance.
- Preparing for surgery.
- Determination of the effectiveness of injections of steroids, used to combat pain syndrome.
- Determination of other causes of pain in the back.
- Definition of infectious pathologies of the spine.
- Revealing of malignant formations.
- Detection of inflammation of the spinal cord or nerve endings.
At what conditions is the magnetic resonance imaging of the spine
MRI of the spine is performed in such cases:
- pain in the back area;
- back injury;
- inflammation - for example, spondylitis or Bekhterev's disease;
- degenerative processes in the vertebrae and discs;
- destructive or necrotic changes - tuberculosis spondylitis, osteomyelitis;
- vascular disorders - malformation;
- problems with blood circulation in the spinal cord;
- demyelinating diseases - Guillain-Barre syndrome, multiple sclerosis, etc .;
- anomalies in the development of the spine.
It is worth considering that MRI has many advantages, so it is so actively used in medicine. The merits of research include the following:
- MRI is considered a non-invasive technique, in addition, it does not require the use of hazardous radiation.
- After the procedure it is possible to obtain better and more detailed images. Through the MRI, it is possible to detect injuries, disorders and abnormalities of the spine, which can not be determined in other cases.
- During the study, it is possible to detect pathologies that may not be noticeable due to bones.
- Contrast with MRI significantly provokes allergic reactions.
- MRI is considered an extremely informative diagnostic method. This procedure is especially useful when revealing the substrate of compression of the spinal cord.
- With MRI, it is possible to detect changes in the spine that may be present in the early stages of tumor formation or infection.
- MRI allows you to evaluate potential complications after performing spinal interventions.
Contraindications for carrying out
Like other diagnostic procedures, MRI has a number of contraindications.
Since the study is associated with the effects of radio waves on the body, it does not pass patients who have pacemakers or metal implants.
Also, this procedure is contraindicated for people with bullet wounds that have metal particles in the body.
Also, the main contraindications include severe mental disorders and claustrophobia.
For the rest of the people, tomography will not do harm if you follow the safety rules.However, it is worth taking into account certain research risks:
- Although a strong magnetic field does not harm human health, embedded devices with metal in the composition may not work properly.
- There is always a slight threat of allergies when contrast is introduced. Such reactions can be easily eliminated by medication.
- The only dangerous complication of the procedure may be nephrogenic systemic fibrosis. This condition is extremely rare. If the patient is correctly prepared, this influence can be minimized.
- If the MRI with contrast is performed during lactation, the mother should not feed the baby 1-2 days after the procedure.
During the research, a person needs to lie still for a long time, which can cause some discomfort. Especially it concerns those patients who have a strong pain syndrome.
Preparation for the survey
When performing MRI, the patient can take advantage of special clothing. It's also possible to be in your things, but they should be free and not contain metal.
There are no restrictions on food intake, however, doctors recommend that you refrain from eating a few hours before the procedure.
It is very important when it is planned to carry out MRI with contrast.
Also, before using contrast, the physician should obtain information regarding the presence of an allergy to the substance used or bronchial asthma.
Most often, a contrast is used for MRI with gadolinium in the composition. Although this substance rarely provokes complications, it is not recommended for use in dangerous diseases. This must be taken into account in kidney diseases.
If MRI is performed by women, the doctor should be provided with information on the possibility of pregnancy.
Although in the course of long studies there was no adverse effect on the fetus, MRI during pregnancy is not recommended, especially in the first trimester.
The procedure with contrast is shown only in exceptional cases.
If a person has claustrophobia, it is worth using open-type devices. Also, the patient can ask the doctor for a mild sedative.
.If the study is necessary for a small child, he is shown mandatory introduction of sedatives.
.This procedure is performed by an anesthetist so that the child can lie still.
To get objective results, you need to remove all objects from the body that contain metal. In the treatment room, there can be no metal or electronic objects, since they affect the functioning of the magnet. To such subjects carry:
- ornaments, watches, credit cards;
- Hearing Aids;
- piercing;
- dentures;
- pins and studs;
- pens, glasses, etc.
It must also be taken into account that MRI is not performed for people who have such devices:
- heart valves;
- cochlear implants;
- metal stents, etc .;
- clips used for aneurysms;
- embedded instruments - in particular, a pacemaker or defibrillator;
- Joint endoprostheses, which contain metal;
- infusion pumps;
- stimulators of nerves.
Parents accompanying the child, too, must remove all objects from the metal or inform the doctor about the presence in the body of such objects.
How to do the procedure
A conventional closed apparatus is a tube of cylindrical shape, around which there is a magnet. During the procedure, the patient needs to lie down on the moving table, which is directed to the center of the magnet. The computer system with which images are processed is in the next room.
The photo shows the device for MRI of the spine
Also there are devices of open type. Such devices do not completely surround a person. They are suitable for people who have claustrophobia or heavy weight.
Modern open tomographs allow you to get clear images. If an old magnet is used in the device, the picture quality may not be too good. Separate types of research on such devices are not carried out.
The coils are placed on that part of the spine to be examined. Depending on the manifestations of the disease, the doctor can prescribe a scan of only one department of the spine.
If you want to apply contrast, a catheter is inserted into the patient's vein, to which a vial of saline is connected. Thanks to this, it is possible to constantly flush the system to prevent its clogging.
The procedure is completely painless, but some patients experience heat in the area under investigation. This is considered a normal response to the effects of magnetic radiation. If the patient has a significant discomfort, it is absolutely worth telling the doctor.
Usually the patient remains alone in the hardware room, but between the doctor and the person there is a two-way audio connection. In addition, the doctor sees a person. After the procedure, the patient does not need any time for adaptation.
About the price
The cost of this procedure is influenced by quite a lot of factors - the clinic's fame, equipment, scope of research. So, MRI of all parts of the spine will cost about 1, 00-1, 00 rubles. At the same time, an analysis of one of the departments will cost about 5000-6000 rubles.
MRI of the spine is considered a very reliable and accurate type of research.This procedure does not cause pain and is absolutely safe for human health. Therefore, do not abandon this study, if there are strict testimony to its conduct.

How does an MRI scan the spine: how to prepare for the study, contraindications and cost
MRI of the spine, or magnetic resonance imaging of the spine, is currently considered one of the best and safe methods of diagnostic examination of osteoarticular and muscular diseases of the spinal cord and spine in whole.
What is MRI of the spine and what is it for?
Magnetic resonance imaging of the spine, or MRI of the back is a diagnostic study of an anatomical object, a layered image of which is obtained in a three-dimensional projection.
Tomography of the spine or its parts, passes with the use of nuclear magnetic resonance - physical measurement of the electromagnetic response of hydrogen atoms to resonance excitation of the investigated object.
The year of the founding of magnetic resonance imaging is 1973, when American physicians led by Paul Christian Lauterbur opened this unique method of magnetically resonant induced image of the structural interaction of anatomical objects of the body rights. The first magnetic resonance tomograph, for which the American scientist received the Nobel Prize in 2003, has been stored for many years at New York University in Stony Brook. However, the sluggishness of the Soviet state agencies on inventions, did not allow the Russian scientist Vladislav Aleksandrovich Ivanov, to claim the primacy in the invention of magnetic resonance imaging, which he sent to the State Committee of the USSR back in 1960 year.
Why do MRI: its types, advantages and features
The procedure of MRI of the spine is conducted with the purpose of revealing various diseases of the musculoskeletal system.
Conclusion MRI is deciphered based on the results obtained after saturation of the structural tissues of the osteoarticular elements of the spine by the nuclear resonance of the hydrogen proton.
Tomography of the spine is not the only way to diagnose magnetic resonance imaging. There are other types of magnetic tomography of the spine that can detect pathological abnormalities in the human body:
- MRI of the spinal cord.
- MRI of the head (pituitary gland).
- MRI of any parts of the spine.
- MRI of abdominal organs and so on.
In comparison with ultrasound (ultrasound), the method of MRI of the back or other structural components organism is a more sensitive, accurate and informative way of laboratory instrumental diagnostics.
Magnetic resonance imaging of the spine (ridge) will show the projection scan of different angles and planes of individual elements of the musculoskeletal system of the spinal column.
Obtained tomography data, or pictures of the passage of MRI of the entire spine, will help with the reconstruction of the support system in further, when suddenly there will be other painful symptoms and signs requiring therapeutic or surgical treatment.
What is this MRI of the spine, is it scary to do and how to prepare
First of all, it should be noted that the procedure for MRI of the back determines the following clinical conditions and / or pathological manifestations in the osteoarticular organization of the spinal column:
- Conduct an examination of MRI signs for the presence of congenital abnormalities of the cervical, thoracic or lumbosacral section (i.e. e. waist).
- Determine the state of intervertebral discs.
- MRI of the vertebrae can detect spinal stenosis, when the narrowing of the spinal canal occurs.
- The MRI method determines the degree of compression pressure on the nerve roots in the intervertebral segments.
- The MRI monitor shows the effect of harmful components and / or other substances on bone tissue or nerve fibers, in the case of the appearance of a tumor-like tumor, cyst or bone abscess.
- Diagnostic application of resonance tomography, allows to determine the inadequacy of blood circulation in the vessels in a certain area of the osteoarticular structure of the spine.
- Finally, the results of the MRI of the spine provide a complete diagnostic picture, in the case of an infected lesion of the osseous and articular and muscular components of the musculoskeletal system.
Contraindications to MRI of the spine can be various chronic diseases and conditions, neuro-psychiatric abnormalities of the patient, hormonal failure in women during menstruation.
Thus, we determine who should not do an MRI:
- Do not conduct a diagnostic examination of patients with obvious mental disorders.
- Patients with epilepsy, or with frequent cramps of the upper or lower extremities.
- MRI can not be performed by people with orthopedic support metals in the osseous and articular segments.
- Contraindication is also a pacemaker.
Also, when introducing a contrast agent, you need to make sure that the patient does not have an allergic dependence on the offered medical preparation, and in case of pregnancy, it is necessary to inform the doctor-diagnostician about it. If the menstrual cycle is broken, then the doctor should also know about it.
How does the MRI procedure go and prepare for it?
Before making an MRI, it should be borne in mind that the diagnostic measure involves the effect of a magnetic field on the human body.
Therefore, precautions and safety measures must be observed.
The whole preparation for the MRI of the spine consists in removing various ornaments and objects attracted by the magnet, for example, coins, keys, magnetic cards, etc.
You can eat and drink, but it is better to do it for 2 hours before the appointment of the diagnostic procedure.
.Such restrictions correspond to certain physiological needs of a person, when at the most inopportune moment, I want to leave the diagnostic capsule.
.Patient should be patient, as the whole process (the duration of the procedure) usually takes from 15-20 to 45-60 minutes.
Contrast examination
Several other conditions exist when preparing for MRI with contrast.
After carrying out biochemical laboratory tests (analyzes), the attending physician, on special medical indications, before carrying out the diagnostic procedure appoints an introduction to the venous artery special coloring drug to get a clear idea of the abnormal zone.
A person is invited to get acquainted with the conditions of contrasting, and sign an appropriate contract, about the possible risks of the appointment of magnetic resonance imaging with a contrast agent.
Prepared dyes can detect an increase or decrease in the diagnosed musculoskeletal joint or other organ of vital activity, as well as determine the extent of its damage, or lack of such.
Passing through the muscle tissue dyeing drugs, changing the color, determine the clear boundaries of a clinical pathology. The speed of staining depends on the intensity of the main blood flow.
Due to this diagnostic effect, the accuracy of the tomogram improves at times.
For the diagnosis of magnetic resonance scanning, the gadolinium salt is used, which differs from other substances by its low toxicity, fast solubility and high efficiency. At the present time, the Ministry of Health of the Russian Federation has approved other contrasts containing in its composition the main drug component - gadolinium:
- omnixan;
- the doltar;
- gadovist;
- premovist;
- magnevist.
Other coloring substances for magnetic resonance imaging that have not been certified by the Ministry of Health of Russia are prohibited.
Absolute contraindications:
- pregnancy of a woman up to 2 weeks;
- individual intolerance of the active substance;
- children under 15 years.
Relative contraindications:
- dehydration of the body;
- allergic reactions to any kinds of medicinal forms;
- renal and hepatic impairment;
- severe cardiac and / or vascular pathologies;
- chronic diseases of the bronchopulmonary system;
- anemia of organs of vital activity;
- myeloma, polycythemia, etc.
Possible risks and consequences of tomography with contrast
For the diagnostic examination, take a minimal dosage of the coloring component to reduce the risk of possible complications:
- itching of the skin;
- an allergic reaction;
- cough, wheezing, or sneezing;
- painful discomfort in the eyes.
As you can see, the list of contraindications and negative consequences is negligible, and is about 1% of the total the number of possible complications, so do not be afraid of diagnostic procedures, you need and you can go through them boldly.
How long and how does the MRI of the spine
The duration of the magnetic resonance scan is determined by medical indications, depending on the complexity of the clinical pathology and other factors.
MRI can be done in 15-20 minutes, and you can spend more than an hour. The basis of the diagnostic method is local and / or permanent electromagnetic fields, as well as high-frequency energy of the power current.
During the diagnostic examination, the patient is in a pressure chamber, or scanner. The powerful force action of the magnetic field makes alignment of hydrogen protons in the tissue structures of the musculoskeletal system of man.
.By means of radio frequencies signals of subatomic particles of tissue fibers are transmitted to the tomograph receiver.
.The doctor-diagnostician on a powerful tomograph monitor, with a fairly decent expansion, sees the image of individual particles body, and due to the huge number of radio frequency signals, begins processing them on a diagnostic equipment. Such a method of clinical diagnosis of the state of vertebral structures, allows you to identify possible traumatic injuries of the osteoarticular elements, to identify the vascular pathology, bleeding, infection of bone and / or articular segments, and also to prevent the possible development of future clinical complications or pathological formations. In addition, the interpretation of the MRI of the spine (tomogram) allows you to confirm or exclude the clinical conditions that were detected during diagnosis of computed tomography (CT), ultrasound scanning (ultrasound) or radiological examination of bone and / or joint segments the spine.
How often can you do MRI of the spine
The undisputed advantage of magnetic resonance imaging, in comparison with radiography, is the absence of ionizing radiation and a more informative diagnostic picture.
Argumented evidence of the negative impact of the magnetic field on the human body does not exist yet. Complicating factors of deterioration of state of health after the magnetic resonance effect are also not fixed.
Therefore, it is considered that the MRI procedure, if necessary, can be administered several times a year.
Re-examination is a clarifying diagnostic procedure that allows you to determine the effectiveness of the treatment process or to confirm the recovery of the organ of vital activity. However, medical experts are inclined to believe that a repeat examination for children under 15 should not be conducted more than 2 times a year.
How to decode a snapshot
The interpretation of MRI data requires a high level of training from a specialist:
- knowledge of the topographic location of the joint and bone segments of the skeletal framework;
- possession of pathological anatomy;
- understanding of morphological, histological, biochemical and physiological processes in the human body.
Based on this knowledge, the doctor-diagnostician determines the relationship between the form and the interposition of organs among themselves. In the literal translation, the word tomography from ancient Greek means a cross-section.
The task of the expert is to calculate the time during which the hydrogen protons after the action on them will assume their original position. Each pixel on the MRI monitor is a frequency signal, the density of hydrogen atoms and the phase vector, having their own color shades.
.Tomographic images represent a layered image in the transverse and sagittal projection. The quality of the diagnostic test depends on the capacity of the equipment.
.High-field magnetic resonance tomographs give a magnetic field strength of 5-7 T, which makes it possible to obtain a more accurate picture of the location of the pathological abnormality. To establish an appropriate diagnosis, information for a specialist is:
- size, shape and number of foci of inflammation;
- color shade of pathological deviation;
- other indirect indicators.
Deciphering the results of MRI of the back is handled by a radiologist.
How much does an MRI of the spine cost?
MRI can be made free of charge as part of the compulsory medical insurance policy.
since this is one of the most expensive diagnostic tests for the musculoskeletal system of the person, for free passage there is a big queue with a waiting period of several months. This is due to the fact that limited quotas are allocated for the free passage of the survey.
In different regions of the country the cost of the procedure can vary from, up to 5 thousand rubles or more.
It all depends on the severity of the bone-joint disease, the location (the upper or lower part of the spine), the type of MRI equipment and the cost of the contrast component.
Of no less importance is the popularity rating of a medical clinic, as well as the timing of the diagnostic procedure. Some diagnostic centers conduct an MRI of the spine in the evening and night hours.
Where can I make a MRI of the spine
As a rule, most regional and, less often, district medical institutions are equipped with diagnostic MRI equipment. In the major cities of the Russian Federation and the CIS countries there are special city telephone recording services for magnetic resonance and computer diagnostics:
in St. Petersburg - 8 (812) 313-26-79; in Moscow - 8 (495) 230-78-55, 8 (499) 519-32-95; in Minsk - 8 (017) 270-21-42, 8 (017) 509-72-42; in Almaty - 7 (727) 331-33-31; in Kiev - 8 (044) 259-78-00, 8 (044) 321-09-33.
Registering for the night or for the weekend, you can significantly save your budget.
