UZDG (ultrasound dopplerography) refers to special apparatus methods of investigation and is widely used by neurologists. It allows in real time to assess the blood flow through the main shallow arteries and veins. In neurology, ultrasound of the main vessels of the neck and transcranial ultrasound are used. Content 1Principle of USDG 2Which vessels are examined 3UZDG technique 4Indications 5How do the results 6Advantages and disadvantages Principle of USDG The method is based on t...
Myelography is a method of diagnosis, carried out by introducing a contrast medium into the subarachnoid space of the spinal cord followed by fluoroscopy. This technique allows you to diagnose a number of diseases of the nervous system that are invisible when performing a simple X-ray study. The usual radiography of the spine shows only its bone structure, and it is not possible to evaluate the state of the spinal cord, its membranes and roots on the radiograph. It is these structures that w...
Spinal puncture is the introduction of a special needle into the subarachnoid space of the spinal cord in order to take a cerebrospinal fluid for research or for therapeutic purposes. This manipulation has many synonyms: lumbar puncture, lumbar puncture, lumbar puncture, puncture of the subarachnoid space of the spinal cord. In this article we will talk about the indications and contraindications to this procedure, the technique of its conduct and possible complications. C...
Duplex scanning of brachiocephalic arteries( BSA) is a complex ultrasound study of the vessels of the head and neck. Non-invasiveness, safety, absence of strict contra-indications and age limitations in combination with sufficiently high informativeness make it one of the main diagnostic techniques in angioneurology. Contents of the 1 The essence of the 2 method The essence of the 2 method What vessels are examining the 3 What does the du...
Electroencephalography( EEG) is a method of studying the activity of the brain by recording electrical impulses emanating from its various regions. This diagnostic method is carried out by means of a special device, an electroencephalograph, and is highly informative for a variety of diseases of the central nervous system. On the principle of electroencephalography, indications and contraindications to its conduct, as well as the rules of preparation for the study and the method...
Angiography of cerebral vessels is an instrumental method of research, which allows to literally "see" the vessels of the brain. To conduct the study, it is necessary to insert a contrast medium into the corresponding cerebral vessel and the presence of an X-ray apparatus, through which the image of the vessels filled with this contrast will be fixed. Angiography of cerebral vessels is not a routine method of diagnosis, it has its own indications and contraindications, as well a...
Due to its functional characteristics, the brain needs oxygen and nutrients to a much greater extent than many other organs of the human body. Provides delivery of their developed vascular system, "malfunctioning" in which - the narrowing of the vessel, obturation (blockage) it and others - cause a disruption of the work of a particular area of the brain and lead to the development of various unpleasant, and sometimes extremely dangerous, symptoms. To assess the state of the cerebral bloo...
Electromyography is a method of diagnostics that allows estimating the bioelectric activity of muscles, based on which can be concluded on the functional state of the nerve innervating the injured muscle. This study will help the specialist to determine the localization and spread of the lesion, the severity and nature of damage to the muscles and peripheral nerves. About what is electromyography, what are the indications and contraindications to this research, and also about measures of pre...
The term "neurosonography" (NSG) combines at once 3 words: the Greek "neuron" - the nerve and "grapho" - to represent, Latin "sonus" - sound, means the method of studying the organs of the nervous system with the help of ultrasound. As a rule, this term, the synonym of which is "ultrasonography" (USG), means studying the brain exclusively through a large fontanel, but this is not entirely true: it combines a whole group of techniques, among them the USG of the skull, the soft tissues of the ...
Transcranial magnetic stimulation (TKMS) is a relatively "young" treatment and diagnostic technique. It was proposed in 1980 and was initially used rather narrowly, mainly as one of the additional methods of examination in neurology. But in recent decades, such stimulation has been used to treat various diseases. Content 1What is TKMS and how does it work? 2What can you expect from TKMS? 3Motor effects of TKMS 4Indications 5When TKMS can not be done 6How to conduct TKMS 7Possible si...
