Rheoencephalography is a non-invasive functional diagnosis. The method is based on the resistance of the tissues of the human body to electric current. With the help of REG it is possible to obtain information about the elasticity / tone / overall functionality of the vascular walls, the value of the pulse blood supply, vascular resistance and reactivity of the brain vessels.
The study evaluated the overall functionality of the venous and arterial systems. The main advantage of the method is simplicity. Research does not require expensive equipment or specially equipped cabinets. Moreover, REG examines absolutely all the vessels of the brain, regardless of diameter.
The study is carried out using electric current. A special “cap” of wires is put on the patient’s head, into which a minimal electric charge is supplied. Its frequency varies from 16 to 300 kHz. The fabric reacts in a certain way to a charge, and a special computer captures this reaction. The study does not bring pain or discomfort to the patient.
It is important to understand that rheoencephalography is not enough for a comprehensive study of veins and arteries. The method describes only the functional state of the elastic walls of the vessels, and this is not enough to make an accurate diagnosis. REG allows you to detect a problem in a particular section of the brain and concentrate on its further detailed study.
REG was originally used to track brain function in real time. Now diagnosis is necessary after mechanical damage to the head (to prevent hemorrhage), impaired vascular functionality. An interesting fact is that before the invention of rheoencephalography, migraine was not considered a serious illness. During the attack, other body systems function normally, and the patient himself was considered an absolutely healthy simulator.
|Acute / chronic vascular pathologies of the brain (for example, vertebrobasilar insufficiency)||Mechanical head injuries|
|Atherosclerosis (chronic pathology of the arteries, in which cholesterol accumulates in the lumen of blood vessels)||Chronic / severe headache|
|Migraine (a neurological disease that is characterized by frequent unbearable headache)||Dizziness|
|Stenosis (persistent narrowing of the vascular lumen)||Abrasions / wounds in the area being diagnosed|
|Circulatory dysfunction||It is not recommended to conduct a study of newborns and babies.|
|Stroke (acute cerebrovascular accident)|
|General diagnosis of the state of blood vessels after traumatic brain injury|
|Evaluation of the effectiveness of therapy or individual drugs|
|Intracranial hypertension (increased pressure in the cranial cavity)|
For the examination, a polygraph is required, which will produce the result on a paper tape. This is a special device that supplies electrical pulses to sensors connected to the patient’s head.
Paired electrodes connected to the rheograph are applied to the head of the subject. One of the electrodes gives a signal, which, after passing through the brain tissue, is recorded by the opposite electrode. Since body tissues and blood flow have different electrical conductivity, pulse fluctuations in the vascular bed cause certain data changes. Data is transferred to a computer, which not only captures them, but also sends it to a polygraph.
Charts are recorded on paper, two results are given if blood flow activity in the left and right hemispheres is compared. Also, in parallel with the REG of the head, an electrocardiogram can be recorded to track the compliance of vascular filling and cardiac output.
REG of cerebral vessels or deciphered rheoencephalography, a method of modern medicine in studying the movement of blood in the human brain, without penetrating the skull.
The study, if necessary, of a specific part of the brain, the state of the vessels in it, their walls (tone), how they (quickly or not) are filled with blood, what blood enters them (viscous or not), its rate of flow, time and reaction, vascular behavior.
As a result, the data obtained are displayed by the medical worker on paper in the form of a graph. They are represented by cyclical curved lines (1 cycle per 1 heart beat). This is a rheoencephalogram.
Decoding of REG is carried out by a physician with special knowledge and skills. It correlates the information received with the age of the patient and taking into account the reaction to the functional test.
The curves reflect the response of the vessels of the head to the flow of blood. Part of the line on the ascent is called anacrota, and on the descent – the catacrot; the beginning of the wave is incest. Deciphering the results of the REG requires some time.
So, the data is decrypted by the doctor. To do this, he analyzes the following indicators:
- wave regularity;
- view of the top and its rounding;
- what anacrot and catacrot look like;
- where is incesture located.
After decoding the REG of the cerebral vessels, the doctor makes a conclusion about the type of their work. These types will be:
- The dystonic type of REG is characterized by increased vascular tone with characteristic disorders (hypertonicity plus low pulse pressure);
- Angioedema type REG. Here, a violation predominates, leading to a decrease in tone and a malfunction in blood flow;
- Hypertonic type of REG. This type is characterized by hypertonicity of the walls, as well as a deterioration in the functioning of the veins that divert blood from the brain.
Types alone do not indicate the presence of a disease, but are only diagnostic terms.

Rheoencephalography of cerebral vessels: how the procedure goes
Before the study, it is advisable to refrain from taking medications and consuming substances that affect vascular tone and blood circulation (drugs for the treatment of hypertension, nitroglycerin). If you regularly take such funds, on the eve of the procedure or on the day of its conduct, you should consult with your doctor about the appropriateness of their next reception.
If immediately before the procedure you are agitated, stressed, or have just experienced significant physical exertion, you should calm down and try to relax as much as possible. An indicator of readiness for research can be considered calm breathing and a slow even pulse.
REG is carried out using a device called a rheograph. Modern electrocardiographs also allow the study of cerebral vessels. In the diagnostic room, the doctor places electrodes on the scalp treated with a special conductor composition. They are fixed with elastic rubber tape, after which the device begins to record the impulses that are in progress. The rheograph writes them in the form of graphic symbols (curved lines), which the doctor further deciphers.
Sometimes, to clarify the nature of vascular changes, the doctor prescribes functional tests – vasodilating drugs (papaverine, nitroglycerin, nicotinic acid). In this case, a graphic image is recorded before they are received, and then it is compared with the data obtained after taking vasodilator drugs.
The essence of the method
The essence of the method is that a current is passed through the human brain, it is low-frequency and immediately the electrical resistance of the brain, or rather its tissues, is shown on the monitor screen.
Despite these advantages, many doctors agree that this method has outlived itself (although it is still used in many medical institutions), and replace it with magnetic resonance and computed tomography or ultrasound dopplerography.
Devices with which rheoencephalography of cerebral vessels is carried out are called rheographs, they have several channels, from 2 to 6, which allows you to get results (rheoencephalograms) of several brain regions at once.
Most often, round, metal electrodes are used, which are fixed on a person’s head with tapes made of rubber material in places necessary for research (whiskey, nose bridge, area above the eyebrows, nape), and special pastes are used to enhance their contact with the scalp.
The patient, at the request of the doctor, takes various poses of the head (tilting to the right, left, back, forward), and all the results, which then decipher the readings of the reg vessels of the brain, are recorded. Each age has its own norms of evidence.
Advantages of CT in the clinic of JSC “Medicine” (clinic of academician Roitberg)

What shows and explores REG
Let’s decide what the REG REG of the brain shows.
REG results are volume information about the state of the vessels of the brain.
Based on the indicators, the specialist studies the tone of the vessels, the elasticity of their walls, how quickly blood enters them, how they behave under different loads (tilting and turning the head), and accordingly the outflow of blood from the head.
The results may be the identification of cholesterol growths on the walls of blood vessels, or hematomas, after suffering damage to the skull, a predisposition to the formation of blood clots inside them, the development of intracranial pressure.
What shows ultrasound of the vessels of the brain and what indications for the procedure exist, you can find out from our study.
There are special signs of a stroke in men that differ from symptoms of an attack in women. Knowing which can save a patient’s life.
What is cerebral vascular rheoencephalography? This is a way to see the functioning of blood vessels. It reflects the ratio of an increase in blood volume and opposition to this vascular wall.
After the procedure, the patient will know exactly how fast the blood moves, its viscosity and the degree of filling of the vessels.
Rheography is also used as an opportunity to consider the quality of blood vessels of the whole organism:
- Using rheogepatography characterize the vessels of the liver;
- Reovasography, abbreviated as RVG, determines blood flow in the limbs;
- Rheocardiography will show the activity of the vessels of the heart;
- Using reopulmonography, you can evaluate the blood supply to the lungs.
For the most detailed and accurate answer, along with the passage of the REG of the head, doctors use EEG. What is it, and what is the difference between the procedures from each other? REG (rheoencephalography) determines the type of vascular function.
And with electroencephalography, the bioelectrical activity of the brain is displayed.
With a prolonged failure of the functioning of the vessel, the neural activity in this gap also changes.
Thus, diagnostics with the help of REG and EEG in a medical institution will show not only the impaired activity of blood vessels, but also how much damage was done to neurons. The difference between these processes gives information that complement each other.
The occurrence of fainting, epileptic seizures and pain, which cannot be relieved with the help of tablets, is the basis for EEG.
Indications of the bioelectric activity of neurons are read using electrodes attached to the patient’s head and displayed in an encephalogram.
The purpose of the procedures is completely different, so do not confuse them. And the need for their implementation is determined by a specialist.
With the help of an oscilloscope, brain pathologies can also be detected. The obtained diagnostic result appears in the form of an oscillogram.
Indications for the study
When our body as a whole works uniformly, there is no particular indication in the study of its work.
But external factors (temperature changes, pressure fluctuations in the atmosphere, movement from one climatic zone to another) often interfere with the activity of our body, thereby affecting it and its components.
Vessels are no exception. They wear out, do not withstand the impact, and failures occur with stress or excitement. REG allows you to identify them.
The following main indications for REG REG of the brain are distinguished:
- Cholesterol formations on the walls of blood vessels violate their elasticity, the patient develops an atherosclerotic process, which in most cases leads to myocardial infarction or stroke. (REG is prescribed for a stroke or heart attack. If the patient is hypertensive or has a disease – vegetative-vascular dystonia).
- A predisposition or the formation of blood clots, with their further separation and blockage of the vessel, leads to ischemic stroke (with cerebral ischemia or if there are symptoms of its development).
- Past head injuries for no apparent reason (pain, dizziness) lead to the appearance of intracranial pressure or hemorrhage in the brain tissue (with concussion or contusion).
- Headaches, migraines, are the result of improper blood flow in the vessels of the head (with headaches, tinnitus, disturbance of the vestibular apparatus).
- With insomnia, decreased vision, fainting.
For the study of REG used specialized equipment called “rheograph”.
This is a multi-channel device (from 2 to 6 channels), which, using a high-frequency generator, takes readings and presents them in the form of a graphic image, which is further decrypted by the doctor.
Data on the work of cerebral vessels is read out thanks to metal electrodes attached to the head, interconnected by elastic bands.
What does preparation for the procedure include and what does it consist of? The key to a successful result lies in the patient’s peace of mind. How is information collected?
- Before starting, it is enough to lie down, close your eyes, drive away all unnecessary thoughts and rest for about 20 minutes;
- It is also worth giving up smoking, at least a couple of hours before taking the testimony, and not using medicines that can affect blood vessels and blood flow;
- In the place of fixing the electrode, degrease the skin, apply a paste for better conductivity;
- After fixing all the electrodes include a rheograph;
- There is a registration of brain waves.
To compare the indicators in a calm and excited state, the patient may be asked to take a deep breath several times or take drugs that affect the blood flow, and repeat the process. These events are called functional tests.
The process of conducting studies using rheoencephalography of cerebral vessels is simple. The only condition is calm.
The patient lies on his back with his eyes closed on honey. sofa. The doctor degreases the studied areas of the head with alcohol and puts metal electrodes on them, which, to improve sensitivity, are lubricated with contact paste.
The electrodes are secured with rubber bands. A weak current is passed through the electrodes, with the help of which the blood vessels of the brain are recorded. “Curved lines” appear on the monitor screen – indicators of the functioning of blood vessels and blood flow.
Preparation for the procedure takes about 5 minutes. The specialist degreases the studied areas of the patient and fixes metal electrodes on them.
Perhaps you want to know about the new medication - Cardiol, which perfectly normalizes blood pressure. Cardiol capsules are an excellent tool for the prevention of many heart diseases, because they contain unique components. This drug is superior in its therapeutic properties to such drugs: Detonic. If you want to know detailed information about Cardiol, go to the .There you will find answers to questions related to the use of this drug, customer reviews and doctors. You can also find out the Cardiol capsules in your country and the delivery conditions. Some people manage to get a 50% discount on the purchase of this drug (how to do this and buy pills for the treatment of hypertension for 39 euros is written on the official website of the manufacturer.), ,
The process went
The technique is safe and painless.
Since a 15-minute break or rest is recommended before starting, the patient takes about 25-30 minutes in total for it (at this time the preparatory process also enters).
It is recommended not to smoke 2-3 hours before the start of the procedure, not to take all drugs that affect blood circulation in the body per day. Spend it in a lying or sitting position.
The advantages of the study compared to other methods
REG is often confused with electroencephalography, apparently due to the similarity of names and methodology. But this approach is fundamentally wrong, since the EEG registers the electrical activity of neurons, and the REG measures the electrical resistance of the brain.
Diagnosed diseases are also different. For example, EEG is the gold standard for the diagnosis of epilepsy, and REG is the migraine.
Another similar method is USDG. This method examines the blood vessels, the nature of the blood flow in the vessel, but it displays organic pathology: the presence of blood clots, atherosclerotic plaques, aneurysms, constrictions.
REG has its advantages:
- low cost;
- performed without patient preparation;
- the study lasts only 15-20 minutes;
- has a minimum number of contraindications;
- can be carried out at any age (except for babies), and even during pregnancy.
Many doctors in medical forums dispute ignoring REG and replacing it with more modern research methods.
Those who are opposed argue that the bones of the skull are not able to conduct enough current (resistance is present), and the results of the study of internal vessels are not accurate, all indicators show only the state near the lying vessels.
To refute this, articles by medical scientists about the fact that the bones of the skull are not an obstacle due to the possession of mainly capacitive resistance are given.
The advantage of this method is that it is not able to influence external factors (human body tissues, signal amplitude, wave propagation), while other methods are subject to these phenomena.
Younger doctors are increasingly giving preference to new methods for determining the state of the circulatory system, such as computed tomography and Doppler ultrasound.
And the older generation adheres to the time-tested and simple REG procedure.
Patients are usually satisfied with the result. Moms can reassure the baby by taking him in his arms during the diagnosis, unlike an MRI, where it is difficult for the child to maintain complete calm inside a large and noisy device.
It is possible to use this diagnostic technique in a clinic dealing with blood vessels.
Taking care of your health is the task of every person. A full life will bring more joy if it does not overshadow the headache and other related problems.
Average prices and reviews
Depending on the quality of the equipment and the type of ownership of the institution, you will have to pay from 900 to 7000 rubles to make a REG, the holders of the compulsory medical insurance policy (MHI) are examined for free if there is a referral from the attending physician.
As a rule, patients calmly tolerate the study, after the procedure, the reviews are always positive.
Svetlana, 54 years old
For a long time I suffer from arterial hypertension, but I take drugs irregularly. Recently, she began to notice a shaky gait, frequent dizziness, and sleep disturbance. The attending physician directed to the REG, which confirmed the changes in the blood supply to the brain associated with my underlying disease. It is good that the procedure turned out to be inexpensive, painless and informative. Now the doctor selects the combination and dosage of drugs, and I already feel better.
I am very afraid of the doctors and all the manipulations carried out with me. It is so good that the REG procedure turned out to be short in time, absolutely painless. In vain worried. Only this method helped confirm the presence of migraine.
Anatoly, 67 years old
I have long been noted high blood pressure. But he didn’t go to the doctors, he didn’t take any medicine. A month ago, my head began to hurt often, especially in the back of my head. The doctor ordered a REG, according to the results of which they determined some kind of violation. It’s good that the procedure is quick and inexpensive. A more detailed study was appointed, which helped establish an accurate diagnosis. ”
I suffer from a constant headache for many years. Often passed EEG, MRI, other examinations, but the cause could not be identified. The new attending physician directed to the REG, which revealed a narrowing of the vertebral artery. Now there is a long treatment.
Now, many doctors believe that in its informativeness, REG is significantly inferior to modern diagnostic methods. But discounting this study is not worth it.
In the case of VSD and migraine, rheography is the only way to confirm the diagnosis.
Doctors differ on their age. Young specialists put forward their opinions for the use of new methods (computer, ultrasound) research, older specialists adhere to REG.
But there are no negative reviews and calls for not using this technique. Patients are satisfied.
This is especially true for mothers with young children, who can be seated on their knees, where the child feels safe, or senior citizens who, in preparation for the procedure, can lie down and talk with the doctor during the diagnosis process.
The cost of the procedure
The price of REG of cerebral vessels ranges from 1000 to 3500 rubles. Where to get the test and for what amount, the patient chooses.
It is worth noting that it is better to do this in specialized centers equipped with modern equipment, and with the presence of several specialists who together can make an accurate diagnosis in difficult cases and prescribe treatment.
Many clinics offer their services for carrying out this procedure at the patient’s home, then the cost increases to the amount of 10 rubles to 000 rubles.
How is rheoencephalography performed?
As a recording device, a two or six-channel rheograph (rheoencephalograph) is used.
The more channels, the more informative the study:
- The patient is seated on a chair with a back. It is important that the posture is relaxed, because any tension in the body is reflected in the bloodstream, which in turn will affect the result.
- The patient’s skin on which the electrodes will be installed is cleaned, wiped with a solution for degreasing.
- Under the electrodes, a lining of absorbent material soaked in a dielectric solution is placed, or treated with a gel-conductor to increase conductivity.
- The whole procedure lasts no more than 15-20 minutes. Functional tests are often used to assess vascular reactivity: with turning the head or tilting it, changing the respiratory rate.
- For children, the procedure is the same as for adults. Not always a child is able to calmly sit out the required amount of time. In this situation, only parents can help.
To determine what type of pathology the violation belongs to (organic or functional), pharmacological tests are used with drugs that affect the vascular network. Use nitroglycerin, aminophylline, nicotinamide. Changing the appearance of the rheoencephalogram, they allow you to more accurately understand the nature of the violations.
Since the diagnosis of the head with the help of REG is absolutely safe, this procedure can be performed for children of any age. A neonatal examination of this type is not carried out, since neurosonography is sufficient to obtain data on blood flow in the infant’s brain.
In some cases, there is a problem with data acquisition, since it is desirable to conduct an REG with complete immobility of the patient. Not every child will be able to sit quietly, even if the procedure takes only 5 minutes. Therefore, the increased mobility of a small patient can also be a reason for refusing to conduct an examination. With rheoencephalogram, anesthesia is not used, since it is impractical to use it for such a short period of time.
The child undergoes REG together with one of the parents. So that the baby feels confident, can sit quietly, you can take him in your arms. If the patient is crying, afraid, screaming, the procedure is canceled.
When it is not possible to undergo an MRI or CT scan due to contraindications, but it is necessary to check the state of blood flow, it makes sense to agree to REG. Examination of the head with rheoencephalography is a simple procedure available to many patients, requiring no special preparation.
This examination method does not require special preparation before the procedure, so all the necessary preparations before diagnosis take about 5 minutes. At this time, the doctor treats areas of the patient’s body with a special tool for degreasing the surface and then places the electrodes in these places necessary for the examination.
After the electrodes have been installed on the patient’s head, a weak current is passed. The sensors record the difference between the values detected between the electrical conductivity of the soft tissues and the patient’s blood, which is displayed in the form of a curve line similar to a cardiogram, on which the received fluctuations are noted.
Directly during the study, the patient is in a lying or sitting position. At the same time, the doctor may ask him to move a little, move his head up and down, or right or left, or even squeeze a little carotid artery in order to note changes in the indications and determine how the vessels respond to the impact in one or another position.
During the study, it is very important that the patient is calm and not worried, because due to nervous tension caused by a stressful situation, the vessels of the brain are narrowed, which makes the diagnostic results not entirely accurate and informative.
