Why and how is MRI examination of blood vessels performed? MRI of cerebral vessels: what does it show? Is special training needed?

MRI of cerebral vessels currently one of the most informative and safe methods for diagnosing cerebrovascular diseases, as it allows for three-dimensional reconstruction of both arteries (MRI arteriography) and veins (venography). In addition, MRI allows you to visualize nearby brain tissue, which is especially important when it is necessary to diagnose strokes. Images of nearby tissues have high clarity and, therefore, MRI examination allows diagnosing microstrokes and small tumors. MRI of cerebral vessels makes it possible to visualize not only morphological changes in the vascular bed, but also to determine the speed of blood flow. Doesn't use MRI ionizing radiation and therefore examinations can be repeated quite often. MRI of brain vessels is possible only on high-field devices (1 or more Tesla), since high resolution is required. MRI of cerebral vessels very informative and can provide sufficient information about the condition of the vessels even without the use of contrast.

Cerebral vascular abnormalities, which are pathologies of the arteries and veins, can lead to life-threatening conditions. As a rule, MRI of cerebral vessels is indicated when it is necessary to exclude an aneurysm, developmental abnormalities (vascular malformations), or to search for the source of bleeding.

MRI of brain vessels allows you to evaluate:

Internal carotid arteries
Basilar arteries
Circle of Willis ( arterial system which is the basis of the blood supply to the brain)
Venous vessels (venous sinuses)
MRI of cerebral vessels also allows us to partially assess the condition of the brain tissue, pituitary gland, and brain stem.

Given its high resolution, MRI examination of blood vessels is significantly more informative than research methods such as CT, X-ray or ultrasound.

Indications for MRI of cerebral vessels:

Cerebral circulatory disorders
Vertebrobasilar insufficiency
Acute ischemic stroke
Cerebral aneurysms
Vascular malformations
Tinnitus of unknown origin
Intracranial hypertension
Headaches of unknown origin
Arachnoiditis
Anomalies of vascular development
Dissecting aneurysm
Brain injuries (bruise, concussion)
Vegetative-vascular dystonia
Nosebleeds
Atherosclerosis of cerebral vessels

Contraindications for MRI of cerebral vessels:

Clips on vessels
Some types of artificial heart valves
Defibrillators or cardiac pacemakers
Cochlear implants
Kidney disease (if contrast injection is necessary)
Joint endoprostheses
Some types of vascular stents
Dental prostheses with metal.

MRI of brain vessels can be performed without the use of contrast and allows you to visualize not only the vessels, but also nearby tissues. In addition, the advantage of MRI research is the ability to visualize tissue, but also determine the functional characteristics of blood flow. If necessary, an MRI with contrast can be performed.

IN modern diagnostics MRI is one of the most popular and accurate methods for studying pathologies cerebral circulation. Thanks to the lack radiation exposure and the ability to obtain informative data without contrast enhancement MRI of cerebral vessels can be performed on patients of all ages.

MRI of cerebral vessels - indications

Let's consider when an MRI of cerebral vessels is performed and what the examination shows. MR angiography of intracranial vessels makes it possible to determine the width of the vascular lumen, evaluate the characteristics of blood flow, symmetry, size of vessels and other parameters by which a conclusion is made about the state of cerebral blood supply.

The main indications for vascular screening are patient complaints of:

regular or severe headaches;
loss of consciousness, dizziness;
symptoms of increased intracranial pressure;
noise in ears;
constant weakness;
blurred vision;
suffered traumatic brain injuries.

The examination is carried out when choosing treatment tactics and assessing the results of the therapy.

MRA examination of the brain in vascular mode diagnoses:

inflammatory processes of blood vessels;
rheumatic changes;
anomalies in the development of arteries and veins, in particular hypoplasia (congenital narrowness);
strokes;
thrombosis, stenosis, aneurysms, arteriovenous vascular malformations;
tumors vascular system;
infectious disorders;
areas of vascular compression and other results traumatic injuries;
hemorrhages, etc.

Magnetic resonance angiography of the vessels of the head - what is it?

MR angiography (or MR tomography of the brain with a vascular program) is synonymous with the name vascular MRI. Depending on the types of vessels being examined, it can be arteriography (focus on the study of arteries) and venography (focus on the diagnosis of veins).

How to do an MRI of cerebral vessels

Most often, the data obtained as a result of native scanning is sufficient. However, with more in-depth screening for suspected neoplasms, their differentiation, or strokes, the doctor prescribes an MRI with contrast. The drug is administered into the patient’s antecubital vein by a one-time injection or drip throughout the study.

The process of examining MRI of brain vessels and contraindications do not differ from other types of MRI of the head.

The non-contrast scanning procedure takes about 15-20 minutes; an MRI examination of brain vessels with contrast usually takes 10-15 minutes longer. A comprehensive MRI of the veins, arteries of the head and neck is often performed, which takes 30 minutes.

Interpretation of MRI of cerebral vessels

The following vessels are visualized on the images:

intracranial areas of internal carotid arteries;
segments vertebral arteries;
main artery;
cerebral arteries, their distal branches;
posterior and anterior communicating arteries of the circle of Willis;
great cerebral vein;
occipital, parietal, frontal cerebral veins;
internal jugular veins;
straight, transverse, sigmoid and other venous sinuses.

On the resulting images, the doctor evaluates the size, boundaries, bends of blood vessels, symmetry of blood flow, narrowing of the diameter of blood vessels and other parameters, on the basis of which a conclusion is made about any violation.

The images obtained during the study are recorded on disk or printed on film, and their interpretation is drawn up by the doctor on paper in the form of a detailed description. After deciphering the images, the patient should contact a neurologist or other specialist to make a final diagnosis and prescribe treatment.

Where to get an MRI of cerebral vessels in Moscow time

If a person suffers from headaches and dizziness, which are observed over a long period, then experts recommend that he undergo an MRI of the brain vessels. To date this study is considered the most popular and informative, helps to identify pathologies and diseases of the vascular system in the initial stages.

Before undergoing an MRI, including CT, it is necessary to take into account not only the indications, but also the contraindications. The patient must first prepare and follow all recommendations in order to obtain reliable results.

MRI, or magnetic resonance imaging, is a safe, informative and effective method studies of various parts and systems of the body. During such an examination, no substances are administered to the patient that could harm his well-being.

MRI uses a magnetic field and radiofrequency pulses. The program allows you to obtain a clear image of the area under study, helps to place accurate diagnosis and based on this, prescribe effective, correct treatment.

MRI of the brain and blood vessels shows the specialist a clear and understandable image:

brain;
vessels of this organ;
pituitary gland;
eye orbits;
paranasal sinuses;
temporomandibular joint.

This examination provides the doctor with full information not only about the structure of the brain, but also about the biochemical processes that occur in it. The images can help identify the causes of headaches, migraines and dizziness. MRI of the head vessels also helps evaluate vision, the pharynx, mouth and nose. It is also worth saying that the magnetic resonance examination method is not invasive.

Indications and contraindications for MRI of the brain

MRI is considered safe method examination, but there are still categories of patients who cannot undergo it. Before prescribing a tomography, the specialist interviews the patient to rule out possible complications.

Contraindications to MRI of cerebral vessels:

Excess weight (weight more than 130 kg).
Lung diseases and GERD.
Presence of pacemakers.
Availability metal prostheses, plates in the body, braces, rods that stabilize the spine.
Availability of hearing aids.

If the patient has any metal particles or elements in the body, then the research will be accompanied by interference that will not allow obtaining reliable result. In such a situation, the specialist will select more suitable option examinations.

It is worth noting that MRI is contraindicated for people with claustrophobia.

As for indications, MRI of the brain is recommended in situations such as:

frequent cephalgia, migraine, dizziness, fainting;
noise in ears;
bleeding from the nose;
impaired memory, attention, concentration;
impaired coordination;
impaired sensitivity;
psychological disorders.

Traumatic brain injury (TBI).
Aortic dissection.
Atherosclerosis and other vascular diseases.
Congenital heart defects.
Stroke.
Neoplasm in the brain.

Which brain vessels can be examined on MRI?

Magnetic resonance imaging allows you to examine:

Arteries (MR angiography) and veins (MR venography). The examination allows us to study the vessels not only of the brain, but also of other systems and organs. In most cases, these methods are prescribed to study the vessels of the head and cervical spine.
MRI of neck vessels. Helps determine the state of the vascular system of a given department, since disturbances can have an impact Negative influence on the state of the brain.

Sometimes diagnosis is made by injecting a contrast agent into the body. It allows you to increase the accuracy of the procedure several times and determine even the most minor deviations in blood vessels, arteries and veins. MRI of cerebral vessels with contrast agent is mandatory when it is necessary to clarify the presence of a neoplasm, and also if:

Deletion has been carried out intervertebral hernia at the neck hotel.
There is a suspicion of a formation in the pituitary gland.
It is necessary to determine the degree of activity of multiple sclerosis.
It is necessary to determine the presence and localization of the formation in the brain or spinal cord, as well as assess their condition after surgery.
It is necessary to identify metastases in the brain.

MRI of cerebral arteries (angiography, MA)

MRI of the brain and cerebral arteries helps to identify lesions of the vascular system and accompanying disorders brain activity. The study also provides complete information about developmental defects, structure, and occlusion. In most cases, MA does not require the introduction of a contrast agent and does not cause radiation exposure to the body.

Severe and frequent headaches and dizziness are noted.
Noise in the ears and head.
It is necessary to exclude or confirm the diagnosis.
It is necessary to monitor the patient's condition after surgery.

In most cases, MA is combined with MRI of the head and vessels of the head, which allows the structure to be more detailed.

Angiography helps diagnose the following pathologies and diseases:

Malformation, aneurysm and other abnormalities.
Anomalies, thrombosis of the arteries of the head.
Vasculitis, etc.

MA with a contrast agent is performed only if it is necessary to determine the state of blood flow in a certain area and assess the condition of blood vessels and arteries. Vascular tomography is performed only as prescribed by a specialist, and if the patient has no contraindications.

Concerning preliminary preparation, then it is not required. MA is a minimally invasive procedure. If you have any questions or doubts about angiography, it is better to consult with a specialist who can make the right decision.

If there warning signs, which indicate the progression of the pathology, then it is necessary to examine not only the brain, but also the blood vessels. MRI helps to examine the condition of not only arteries, but also veins. In the process, attention is paid to their structure, as well as venous flow. Venography is also a non-invasive and safe method.

cephalalgia of unknown origin;
disturbances with memory, coordination, attention, sleep, behavior;
deterioration of visual function;
high intracranial pressure;

Venography helps diagnose diseases such as:

Malformation, aneurysm of veins and arteries.
Neoplasms in the brain and blood vessels.
Various types of thrombosis.
Developmental anomalies.

As for MRI of veins, there are two types:

MR venography of intracranial veins and sinuses without the use of contrast agent.
MR venography of intracranial veins and sinuses and MRI of the brain without the use of contrast agent.

The procedure does not require prior preparation from the patient.

Preparation and execution

MRI in vascular mode does not require any preliminary preparation from the patient, unless the specialist has indicated nothing else.

As for examinations with a contrast agent, it is necessary to avoid eating a couple of hours before the procedure. Before starting, it is recommended to remove all metal objects and jewelry. It is also prohibited to enter the office with electronic devices, electronic plastic cards, pens or glasses with metal frames.

The patient must lie on a special table, his body is secured with belts that can ensure complete immobility. Then it is placed in a large cylinder - a tomograph. If necessary, the patient is first injected with contrast into a vein.

The processing and reception of images is carried out by a computer system, which is located in the next room. Receiving images may take no more than an hour. During the procedure, the patient may note elevated temperature of the surveyed area, painful sensations must be completely absent. Recovery of the body after MRI is not required.

Magnetic resonance imaging (MRI) of cerebral vessels is prescribed when a stroke is suspected, its type is determined (ischemic, hemorrhagic), after a skull injury, or during preparation for surgery. This method is considered one of the most informative, as it helps to identify the cause of the headache, sudden loss consciousness, impaired coordination of movements, loss of vision, mental disorders against the background of vascular diseases.

Its advantages: safety (since there is no radiation), the possibility of research even without the introduction of contrast, no age restrictions. Tomography is performed in vascular mode for damage to intracranial arteries, cervical arteries, and also the venous network. In case of a tumor process, MRI of the brain substance and angiography with contrast are recommended; it helps to determine the degree of tumor growth.

The examination is contraindicated if there are implanted metal products or devices in the body (for example, a pacemaker).

MRI of cerebral vessels - what is it?

MRI of brain vessels is a study of the structure of the walls of arteries, veins and sinuses (collectors between meninges). It can be performed without contrast (native MRI) or with the introduction of a contrast agent. In this case, depending on the purpose, both the intracerebral blood networks and the arterial branches of the neck that supply the brain can be determined.

What is the best way to identify the problem?

MRI of the brain is best performed when diagnosing the condition of the brain tissue itself, and when vascular diseases brain requires vascular tomography. The first diagnostic method is recognized as one of the most informative due to the fact that even the smallest structures are clearly visible:

cranial nerves,
posterior cranial fossa,
brainstem,
pituitary,
hypothalamus.

neuronal damage;
inflammation;
developmental anomalies;
tumors;
injuries;
multiple sclerosis;
Alzheimer's, Pick's, Parkinson's diseases;
during examination before surgery and when assessing its results.

Tomography cerebral vessels helps:

correctly diagnose a stroke (distinguish between ischemic and hemorrhagic);
investigate the risk of rupture due to an aneurysm (protrusion of the artery wall), arteriovenous malformation (congenital vascular anomaly);
assess the blood supply to the tumor and its spread, ingrowth into the vascular network.

Expert opinion

Alena Ariko

Expert in Cardiology

One of the advantages of MRI is the ability to evaluate the structure of the brain, arterial and venous networks without the introduction of contrast. This is possible, since blood, due to its movement and liquid state, itself serves as a kind of contrast agent and gives a hyperintense (amplified) signal.

If it decreases, this means that there is an obstacle to the movement due to vascular spasm or, embolism, compression from the outside (inflammation or tumor process, accumulation of blood).

MRI of cerebral vessels: what the study shows

Examination of cerebral vessels using MRI reveals the cause of headaches, dizziness, episodes of loss of consciousness, visual impairment, mental disorders (only vascular origin), as it shows the condition of the arteries, veins and sinuses of the brain. Tomography will detect: compression, inflammation, wall rupture or its danger, level of blockage, hemorrhage, abnormalities in the structure of blood vessels.

Indications for use

MRI of the cerebral vasculature is indicated for suspected:

rupture of a vessel due to skull trauma, aneurysm or arteriovenous malformation;
benign or malignant tumor;
stroke due to intracranial hemorrhage or artery blockage cholesterol plaque, thrombus;
chronic disturbance of cerebral blood flow (dyscirculatory encephalopathy);
high intracranial pressure (needed to determine the cause and further treatment tactics).

MRI of the brain

When to do it

MRI of brain vessels is recommended when the information content of previous examination methods is low, that is, when the doctor was unable to make a diagnosis, or the therapy for the disease did not produce results. A neurologist can refer the patient for a tomography after the first examination.

Diagnostics are also carried out for:

clarification of data from other research methods (radiography of the skull, CT, fundus examination);
assessing the effect of therapy for trauma, brain surgery, acute disorder cerebral circulation;
choosing a treatment method - surgical or medicinal.

MRI images of a stroke

What symptoms should you go for?

MRI is prescribed for the following symptoms:

constant headaches;
episodes of loss of consciousness;
darkening of the eyes;
noise in ears;
impaired coordination of movements;
unsteadiness when walking;
memory impairment
hearing loss (after excluding pathology by an ENT doctor);
blurred vision (after examination by an ophthalmologist);
sharp fluctuations blood pressure;
with nausea and vomiting;
loss of muscle strength and sensitivity in the limbs on one half of the body;
loss of visual fields;
slurred speech;
migraine attacks;
convulsive muscle twitching;
epileptic seizure;
sudden onset of headache, deterioration of consciousness, swelling of the eyelids, fever (signs of cerebral sinus thrombosis).

Is it possible to do MRI of cerebral vessels in children?

MRI has no age restrictions; it can be done on children from birth. The method is not accompanied by radiation and can be performed without the introduction of a contrast agent. Therefore, it is considered one of the most harmless; when examining and treating a child, it can be repeated as necessary.

Contraindications

MRI is not performed if:

implanted metal or ferromagnetic structures - staples, vascular clips, plates;
braces;
metal fragments;
established electronic devices– hearing or cardiac prosthesis, pacemaker, defibrillator, insulin pump;
tattoo - drawing on the skin with paints and metal;
first 3 months of pregnancy.

Limit the possibility of:

heavy general state patient;
mental disorders;
circulatory and respiratory failure in the stage of decompensation, severe shortness of breath when lying down.

If necessary, MRI is performed in these patients after the administration of medications. If you are afraid of closed spaces and have a body weight of 120 kg or more, it is possible to do tomography only with specially designed devices. Due to allergies to contrast media, contrast angiography is contraindicated and is not recommended in patients with renal failure.

MRI angiography of cerebral vessels

MRI angiography of cerebral vessels is divided into arteriography and venography. This is important, since in arterial diseases there is often a need to assess the condition of the intracardial vascular networks located inside the skull and extracranial, that is, cervical.

Venography examines the venous branches and sinuses between the membranes of the brain. If after preliminary examination If the doctor has doubts about the diagnosis, then arteriography together with venography or MRI of the brain with angiography may be prescribed.

Arteries of the brain

MRI of the cerebral arteries is necessary if you suspect:

Disease	Description
and stroke	Weakness in the limbs on half the body, impaired speech, consciousness, facial asymmetry, severe headache with nausea and vomiting
	Temporary disturbance of cerebral circulation - all signs of a stroke, but they disappear within 24 hours
	Headache, dizziness, memory loss, tinnitus, loss of performance, depressed mood, irritability, tearfulness, impaired coordination of movements, late stage dementia sets in
	Impaired vision, eye movements, severe headache that does not go away after painkillers with nausea and loss of consciousness
Binswanger's disease	in young people due to damage small arteries insomnia occurs, sudden changes in blood pressure, memory and gait deteriorate, and involuntary discharge of urine and feces occurs
	In children, speech, vision, movements and sensitivity in the arm and/or leg are impaired, epilepsy attacks occur, in adults severe migraine-type headaches appear, movements lose coordination
Cerebral vasculitis	Against the background of infection, rheumatism or poisoning, a severe headache begins, limbs weaken, behavior and speech change, vision and hearing suffer, fainting and convulsions occur.

Vascular changes in the brain on MRI appear as a decrease in blood supply to the tissue or accumulation of blood when the artery wall ruptures. It is possible to detect the cause of the headache (tumor, inflammation, vasospasm, blockage with a blood clot).

How to do an MRI of cerebral vessels

MRI of cerebral vessels is done without special preparation; it can be performed on an emergency basis immediately after the patient is hospitalized. If it is prescribed as planned and with the administration of contrast, then it is recommended not to eat for 2 hours.

Before entering the office, you must remove all metal products and leave any electronic devices outside the door. You cannot even take glasses with you, and there should not be any metal elements on your clothes. Such precautions are due to the fact that when ferromagnetic products enter a magnetic field, they become very hot.

The research device looks like a cylindrical tube about 2 meters long. It is surrounded by a magnet. The patient is comfortably placed on the sliding table, and his head and shoulder girdle are secured with straps to ensure immobility during the tomography period. The table moves progressively inside the cylinder. After this, the doctor leaves the office and maintains communication using the built-in microphone.

With and without contrast

The need to administer a contrast agent most often arises when there is a suspicion of tumor formation. Features of the distribution of contrast help to preliminary assess its type - benign or malignant, and in the latter case, its prevalence, metastasis. Contrast is also needed when diagnosing vascular malformations and anatomical modifications of blood vessels.

Contrast contrast is contraindicated if:

drug allergies;
intolerance to gadolinium-based medications (a test before injection is required);
acute and chronic failure kidney function;
severe liver diseases;
exacerbation of bronchial asthma;
administration of contrast for diagnostics for 2 days.

The injection of the drug is performed before the scan and in most patients it causes a feeling of heat, a metallic taste in the mouth, and tingling of the skin. These reactions are considered acceptable and not dangerous to the body. If you experience coughing, difficulty breathing, or the urge to vomit, you should immediately notify your doctor.

The duration of the procedure is about half an hour. Typically, the most unpleasant feeling during a tomography is the loud knocking of the machine, so you can use earplugs if you wish. You may experience a headache after the MRI is completed. general weakness or nausea. It is recommended to drink as much pure as possible drinking water For accelerated removal of contrast, with native MRI, a half-hour rest is sufficient.

Is anesthesia necessary?

MRI of cerebral vessels under anesthesia is prescribed only when the patient cannot maintain complete immobility:

Small children;
fear of the procedure;
mental disorders;
strong pain;
diseases of the joints or spine;
involuntary movements or muscle twitching.

MRI under anesthesia

As a rule, drugs are injected into a vein to put you into medicated sleep and relax the body muscles.

Price of the procedure

MRI of cerebral vessels costs about 4,000 rubles on average, while there is no difference between intracranial arteriography and venography.

In practice, complex studies are most often needed:

MRI of the brain with angiography (venography) – 7,500 rubles;
arteriography and venography – 7,000 rubles;
MRI of the brain + tomography of the intracranial and neck arteries – about 9,500 rubles;
full MRI (brain, neck and cerebral arteries, veins) – 12,000 rubles.

Alternative examination methods

MRI is considered the most informative, provides high-quality images, and is approved for children and pregnant women. If it cannot be performed due to metal elements in the body or other contraindications, then a computed tomography scan is prescribed, often with the introduction of contrast.

A cheaper method is radiography of the skull bones, but it allows us to judge brain tissue only indirectly. To identify vascular pathology a neurologist may recommend Doppler ultrasound; it is safe, however, it does not always help to make the correct diagnosis.

MRI of cerebral vessels is performed to detect atherosclerotic changes, when a stroke is suspected, or to distinguish ischemic from hemorrhagic. It is needed to determine the cause of persistent headache, loss of consciousness, seizures, memory impairment, and hearing loss. It can be with or without a contrast agent. If it is impossible to remain still, it is done under anesthesia.

MRI of cerebral vessels at the clinic "LDC on Vernadsky"

Magnetic resonance imaging at the “Treatment and Diagnostic Center on Vernadsky” is carried out both at the direction of the doctor and at the patient’s own initiative. The price for research in both cases is the same. The cost increases only in cases where there is a need for a procedure with contrast.

Patients who undergo MRI of cerebral vessels in our center have the opportunity to receive not only descriptions of the study, but also images on any electronic medium (for a separate price). In addition, with detailed descriptions You can contact our neurology specialists on the same day for advice and treatment.

Indications for use

MRI of cerebral vessels is necessary in the following conditions:

frequent headaches;
dizziness, fainting;
impaired coordination and gait;
weakness in legs and arms;
changes in skin and proprioceptive sensitivity;
suspicions of volumetric process brain (appearance and growth of a tumor of the central nervous system);
for confirmation congenital pathology cerebral vessels;
For differential diagnosis between ischemic and hemorrhagic stroke.

MRI of brain vessels is also necessary before surgery.

Contraindications

Contraindications are divided into absolute and relative. At absolute contraindications the procedure is strictly prohibited. If the patient has a pacemaker, exposure to MRI may disable it and cause cardiac arrest. This occurs regardless of the area of study: brain vessels or knee joint.

Relative contraindications include:

the presence of metal stents, vascular clips, Elizarov devices;
insulin pump;
patient weight exceeding 130 kilograms.

The presence of ferromagnetic implants during MRI of brain vessels does not disable them and does not affect the operation of the device, but can contribute to a wide field of interference in the image.

The presence of dental crowns, bridges, implants is not a contraindication.

Procedure and preparation

The study does not require special preparation. But to carry out the procedure, you must follow some rules. It is important to remove all ferromagnetic metal objects: rings, chains, clips, buttons. If you have electronic hearing aids, they should be removed. The same goes for an insulin pump.

The MRI procedure of cerebral vessels takes no more than 30 minutes. The patient is placed on a gurney, which is brought into the hemisphere, after which the device is turned on. After the procedure is completed, within 30-40 minutes the doctor prepares a conclusion with which the patient goes to see a doctor. At the Diagnostic and Treatment Center on Vernadsky, diagnosis and treatment can be obtained within one day.
