Brain examination - prevention of health and life
- 14 Aug 12:30
In this article, we will consider various types of human brain examinations. Let's say that it allows us to explore the human body and / or another scanning procedure.
Depending on the reason a person turned to a qualified specialist for the examination of the brain's main, different techniques are used, the most popular of which we will consider below in this article.
- UZDG cerebrovascular
- REG cerebrovascular
- Magnetic resonance imaging
- Magnetic resonance angiography
- Computed tomography brain vessels
Echoencephalography or, as it is called, EhoEg - a unique method in the field of ultrasound diagnosis, aimed at the analysis of pathologies of the brain.
The procedure for echoencephalography is to record ultrasonic signals reflected from the brain, the results of which are clearly shown on the display of the device.
In general, the EhoEG procedure provides a vivid and well-founded reflection on the presence, degree and elimination of all brain structures in the case of a craniocerebral trauma or tumor.
It should be noted that the echoencephalogram procedure is simple, harmless and does not require specialized training.
Brain vessels Another highly successful operation is ultrasound doppler, or, as it is abbreviated, the ultrasound doppler procedure.
It is necessary for proper evaluation of blood flow in the region of large and middle vessels of the neck and head.
In addition, the ultrasound procedure is used to monitor the general condition of the patient, as well as to detect initial pathologies in the vascular bed.
The UDDG procedure in most cases has no contraindications, and it is painless. In addition, it is performed by an outpatient method and does not require special training.
REG of vessels of the brain
REG, or, as it is otherwise called, is a still another method of vascular examination in the field of the brain for its functional state.
Rheoencephalography is based on the recording of changes in the total or partial electrical resistance of live tissues.
This method of studying the brain by pulse fluctuations in its vessels is stipulated. In fact, the regimen procedure is a promising method for varying severity of trauma and brain tumors, as well as epilepsy and migraines. The method is also intended as a research method for fetal hemodynamics.
The survey is carried out using a special multichannel machine called a rheographer. Of course, the larger the number of channels, the more the area will be studied.
How does the regimen procedure look like in turn:
- The patient being examined is placed on the couch;
- He put on his head metal plates that are pre-treated with gel;
- Also, the plates are attached with a special rubber band where it is necessary to evaluate the general condition of the vessels.
Magnetic Resonance Tomography
Magnetic resonance imaging, or MRI, allows you to fully diagnose the localization and nature of lesions, as well as to determine the direction of blood in different parts of the brain with high accuracy.
In addition, this study of the brain through magnetic resonance imaging brings quite good results in case of vascular disease.
For example, if a person has cerebral atherosclerosis. In addition, magnetic resonance imaging helps in the event of a critical period of stroke, as this procedure is capable of detecting thromboembolic myocardial infarction, as well as ischemic blood circulation.
Magnetic resonance angiography
In addition to the well-known to all and each magnetic resonance imaging, there is also another procedure, magnetic resonance angiography.
Today it is one of the promising methods for all kinds of vascular bed diagnostics. In addition, magnetic resonance angiography does not require artery puncture for it.
During the process of conducting magnetic resonance angiography, a qualified specialist gives a unique opportunity not only to diagnose the brain, but also to investigate all possible structural and pathological changes in the vascular brain, as well as correctly and most accurately evaluate the physico-chemical and pathophysiological processes as the whole brain,and its shells and separate structures.
In addition to all of the above, this study of the brain helps to build a three-dimensional reconstruction of the blood vessels, get thin slices and allocate individual trunks and nerve vessels.
To date, magnetic resonance angiography gradually moved to its honorable first place among all types of brain diagnostics.
EEG, or, as it is otherwise called, Electroencephalography - specializes in recording all, even the smallest, vibrations of the brain potentials, which are very simply recorded using a special device - an electroencephalograph.
The procedure proceeds approximately as follows: all electric brain potentials are diverted through special, controlled electrodes. And all the results of the procedure are fixed on paper or on the monitor. Electroencephalography is performed in case of delayed psycho-emotional development, as well as in the presence of human epileptic seizures or injuries.
In addition, the modern, equipped with the latest technology equipment allows for detailed EEG monitoring, that is, the long-term in its time record of all biocurrents in the epilepsies.
ENMG, or Electron neuromicrography - a procedure for recording biocurrents of the muscles.
In addition to the registration, the procedure also gives the most accurate information about the functions and general state of the muscles. ENMG is especially relevant in the case of peripheral nerves in a person, as well as for the most accurate diagnosis of any neuromuscular diseases.
Another procedure for the examination of the brain is neurosonography, which aims to investigate the head of small children for the presence or absence of an overly open fontanel. It is precisely through this very large source that ultrasonic sensors measure the size of the liquid-conducting system, determine the optimal parameters of the blood flow and the structure of the brain.
This method is very informative and, of course, safe. In addition, it allows the optimal time and timely evaluation of the effectiveness and reliability of treatment in the course of the dynamic monitoring. Neurosonography also helps to detect any pathology in children.
Craniography allows with the help of modern equipment to produce a quick and painless examination aimed at identifying congenital defects and fractures of the bones.
At craniography the dose of radiation by X-rays is extremely small, and it is selected for each individual individually.
Snapshots are made in two projections - in profile projection and in the projection of the facsimile.
The technique of conducting craniography includes a number of specialized radiographs, ie:
- Surveillance straight lines, axial and lateral radiographs;
- Images in the temporal bone area;
- Spit Images of Orbits;
- Detailed shots of the Turkish saddle.
Craniography should be conducted in the event of injuries or diseases of the cranial, brain, and subarachnoid sinuses.
Computer tomography of the vessels of the brain
CT, or computed tomography - a detailed examination of the vessels in the brain with a special scanning device.
The device allows you to measure the intensity of X-ray radiation streams with their subsequent passage into the brain tissue, thereby allowing you to get a visual representation of the sections of the brain at different levels of the horizontal planes.
This procedure is performed using scanning equipment, which makes one full turn around the head. Device step size is 1 degree.
The summary information collected is stored on a personal computer, where the calculations are carried out.
Computer tomography helps to detect any birth defects and developmental defects, as well as determine the nature and location of various pathologies.
Doppler is a full-blown ultrasound diagnostic.
It takes into account the frequency fluctuations of ultrasonic waves, which reflect themselves from the active structures of the human body.
This procedure allows you to get the most accurate and accurate information about the status and activity of vessels. In addition, doppler does not require patient preparation for the procedure and is conducted exclusively in outpatient settings.
In which cases is Doppler?
- It is intended for all women who are 32 weeks pregnant;
- In case of complications of pregnancy;
- Suspected of delayed fetal development;
- In case of suspected fetoplacental malnutrition;
- When weighing two or more fruits in one, a common placenta;
- With rhesus-fetal and maternal conflict.
Remember: in order to handle the problem as efficiently as possible, it must first be identified and localized to begin. The examination of the brain in any case will help a qualified medical officer determine the severity of the disease and appoint you appropriate treatment.
