MRI of cerebral, head and neck vessels with and without contrast

Diagnostic scanning of the body using magnetic fields is MRI. Let's consider its features, types, indications, technique and possible complications.

Magnetic resonance imaging of the brain vessels is a study of vascular structures using nuclear magnetic resonance. It allows for an assessment of the brain's bloodstream and the detection of its pathologies and damage.

Obtaining two-dimensional images of blood vessels is performed with and without the use of a contrast agent. In the first case, the contrast fills the vessels, improving the quality of the image. In a non-contrast study, a computer reconstruction of the vascular network is performed based on the blood flow velocity.

MR angiography is aimed at identifying aneurysms, vascular stenosis, developmental anomalies, vascular malformations, and circulatory disorders. The study is also conducted to assess the scope of surgical intervention if there are appropriate indications.

Indications for the procedure

Magnetic resonance imaging of the brain vessels is performed when there are medical indications, let's look at the main ones:

• Severe headaches and dizziness, migraine.
• Impaired hearing and vision.
• Cerebral hemorrhages.
• Ischemic, hemorrhagic stroke.
• Skull pathologies.
• Inflammatory vascular lesion.
• Epilepsy.
• Contusions and head injuries.
• Compression of brain tissue.
• Vascular malformations.
• Atherosclerotic changes.
• Aneurysm of blood vessels.
• Tumor neoplasms.
• Dissection of the walls of blood vessels.

MR angiography is used for dynamic monitoring after operations on the vessels of the brain and in preparation for surgical interventions.

Why do they do MRI of the brain vessels?

The essence of MRI is the use of electromagnetic waves that cause vibrations of hydrogen atom nuclei in the molecules of the human body. That is, the tomograph operates on the principle of nuclear magnetic resonance. It accurately visualizes the structures of the brain, internal organs, and tissues.

• The study is done to identify cerebrovascular accidents, assess blood flow and map the cerebral cortex.
• MRI can be used to detect vessels affected by atherosclerosis, aneurysms, and vascular wall dissection.
• To diagnose processes of venous and arterial malformations, occlusions, stenosis.

The device does not use radiation that is dangerous to the human body and provides the most detailed picture of the tissue being examined.

MRI of the brain vessels in atherosclerosis

Atherosclerosis is an irreversible pathology in which cholesterol and fats are deposited on the inner walls of arteries. The deposits are in the form of plaques and plaque. They thicken the walls of the arteries, which leads to a narrowing of their lumen and difficulty in blood flow, loss of elasticity. The danger of such conditions is the development of ischemic changes and hypoxia of intracerebral tissues.

The main reason for undergoing MRI diagnostics is pathological symptoms of atherosclerosis:

• Impaired coordination and loss of motor skills.
• Sleep disturbances and false urge to urinate.
• Loss of balance.
• Dementia.
• Dysfunction of internal organs.
• Disorders of neurological and mental activity.

The device makes a three-dimensional reconstruction of the brain and its vessels. The procedure is carried out using a contrast agent, which, after spreading through the bloodstream, improves the scanning results. MR angiography reveals atherosclerotic plaques of any size, determines the occlusion of the lumen of the arteries, differentiates the places of curvature of the vessels.

The main stages of the disease according to tomography results:

1. Single inclusions of cholesterol droplets in vessels and arteries.
2. Deposition of platelets and fibrin fibers within cholesterol plaques. Narrowing of the lumen of cerebral arteries, ischemic damage to the parenchyma.
3. Calcium ions are deposited inside the plaque. This manifests itself in spasms of the arteries and attacks of short-term memory loss.

Magnetic resonance imaging diagnoses vascular damage at any stage. The study can detect arterial spasms and other complications of atherosclerosis.

MRI of the brain vessels in stroke

A stroke is a disorder of cerebral circulation with a number of specific symptoms. Depending on the mechanism of origin, the following types of pathology are distinguished:

• Ischemic (blockage of the blood arteries of the brain by a thrombus).
• Hemorrhagic (rupture of a blood artery in the brain or spinal cord).
• Cardioembolic.
• Lacunar (limited foci-cysts formed due to blockage of one of the cerebral arteries).
• Subarachnoid.

According to studies, about 10% of patients fully recover after a stroke, while the remaining 90% face serious complications. Early diagnosis and timely treatment can reduce the risk of the consequences of the disease.

MRI of the brain vessels is the gold standard for diagnosing stroke, as it allows for immediate detection of hemorrhages. The tomograph determines with absolute certainty what type of stroke has occurred, its cause and location. Highly sensitive examination reveals the slightest deviations in the brain: ruptures of the vessel walls, edema, necrosis, circulatory disorders, blood clots, hematomas.

There are general signs of pathology on tomographic images that are characteristic of all types of the disease:

• Signal amplification and its heterogeneity.
• Formation of colliquation cysts.
• Decreased DWI and ICD signal.

After scanning a stroke in the acute period (after 1-7 days), pathological foci are clearly distinguished and delimited against the background of healthy brain tissue. In the subacute period (after 7-21 days), edema resolution is observed. In the chronic period (more than 21 days), complete resolution of edema occurs, expansion of the cortical grooves of the brain and lateral ventricles.

Magnetic resonance imaging is used not only to confirm a stroke, but also for differential diagnostics. Tomography is also indicated for preventive purposes for hypertensive patients and other patients at risk for developing a stroke.

[ 7 ]

MRI of the brain with vessels in hypertension

Hypertension (high blood pressure) is a pathology of the cardiovascular system caused by dysfunction of the vascular regulation centers, renal and endocrine mechanisms, functional and organic changes in the heart.

Hypertension has several types:

1. Essential arterial or primary hypertension develops as an independent chronic disease. In this case, high blood pressure is an imbalance of the body's regulatory systems.
2. Secondary (symptomatic) is a sign of the underlying disease: pathology of the kidneys, thyroid gland, adrenal glands, atherosclerosis, etc.

Magnetic resonance imaging of the brain with vessels in hypertension is one of the most informative diagnostic methods. The study allows to exclude volumetric neoplasms of the kidneys and adrenal glands, anomalies in their development, stenosis of the renal arteries and other pathologies. Based on the results of tomography and laboratory tests, a treatment plan and preventive measures are drawn up.

[ 8 ], [ 9 ]

Preparation

Magnetic resonance imaging, like any other diagnostic procedure, requires special preparation. The patient is examined and additional information is collected:

• The presence of metal objects in the patient’s body: prostheses, dental implants and other foreign bodies with metal elements.
• A comprehensive examination of the body, as well as collecting anamnesis, studying complaints and symptoms, the presence of chronic diseases.
• The presence of injuries, recent surgeries and other damage to the body that may affect the course of the examination.
• To obtain a more accurate image, it is possible to use a contrast agent. In this case, allergy tests should be performed and make sure there are no allergic reactions to the drugs used.

Before the procedure, you should remove all metal jewelry and leave electromagnetic devices. If the patient remains in his clothes, you need to make sure that there are no metal inserts, rivets, buttons, zippers.

Technique MRI of cerebral vessels

After preparation for MRI, the patient is placed on a couch and his position is fixed. When studying the vessels of the brain, the head is fixed in a special support-pillow. If there are indications, a contrast agent is administered. For patients who have difficulty remaining still and children with attention deficit, anesthesia is recommended.

The couch with the patient is moved into the tomograph. Using a magnetic field, the device takes layer-by-layer images of the brain. The results of the study are recorded on a digital medium. This eliminates the need for repeated diagnostics when contacting another specialist. The procedure lasts from 15 to 30 minutes, after which the patient receives a medical report with the results of the examination.

MRI of the brain with vessels with accompanying

A method of layer-by-layer examination of organs and tissues using nuclear magnetic resonance is magnetic resonance tomography. The procedure has a wide range of indications for implementation. The examination is performed on a tomograph, which can be open or closed.

The first one is an open circuit, so a person with claustrophobia (fear of enclosed spaces) can easily endure the procedure.

If the examination is carried out in a closed tomograph, then to calm the nervous system it is allowed to take an accompanying person with you. The latter can be a relative or a close friend, you can also turn on relaxing music.

Types of MRI of the brain with vessels

Magnetic resonance imaging is a highly accurate diagnostic method used to determine the condition of the brain and its components, internal organs and tissues of the body.

Diagnostic scanning of blood vessels is one of the types of MRI of the brain. Also, the scanning areas include: cranial nerves, pituitary gland, temporomandibular joints, paranasal sinuses.

Basic MRI examination techniques:

• Diffuse – provides information about the microstructure of tissues, the presence of edema. Shows the microscopic movement of molecules in water.
• Dynamic contrast tomography – a contrast agent is injected into the patient’s body, after which a series of images or videos of the area being studied are taken.
• Angiography (MRA) – visualizes blood vessels and arteries. Performed with/without contrast.
• Spectroscopy – information about chemical processes in cells. Allows to determine the size and extent of tumor spread.
• Perfusion – visualizes blood flow in the smallest blood vessels (capillaries) and tissues. Used in diagnostics of brain pathologies: tumors, stroke, blood clots.

The studies are differentiated by the use of contrast enhancement:

1. Non-contrast MRI – is performed to visualize the vascular components of the brain (veins, arteries). Most often prescribed for strokes, aneurysms, thromboses and other vascular pathologies. Allows you to evaluate the functional and anatomical features of the bloodstream of the area being examined.
2. MRI with contrast agent – used for a more detailed study of the state of blood vessels. The main indication is suspected oncologic pathology. Gadolinium-based contrast agents visualize vascular structures in detail, identify blood clots and areas with pathological blood supply. Also, derivatives of iron compounds with oxygen or manganese compounds can be used as dyes. The contrast is administered intravenously by drip, bolus or orally.

Diagnostic manipulation is divided according to the type of tomograph used:

• Open – the advantage of such a device is that during the examination the patient does not experience fear of a closed space. Such tomographs are suitable for examining patients with a large weight and height, small children.
• Closed – has a tunnel design. The patient is placed on a couch, which is pushed into the tomograph. Due to the limited space, many patients begin to experience discomfort and claustrophobia.

Also, the study of vessels, that is, MR angiography, can be time-of-flight, when the blood flow velocity through a certain section of the brain vessel is assessed. Four-dimensional angiography is used for separate study of venous and arterial blood.

MRI of the brain vessels with contrast

Magnetic resonance imaging with contrast enhancement has a wide range of indications. The procedure is performed for more detailed visualization of the structure of tissues and body systems.

MRI of the brain and its vessels is indicated in the following cases:

• Diseases of the central nervous system (pituitary tumors, tumors and metastases of the brain, tumor lesions of the cerebellopontine angle).
• Chronic inflammatory diseases of the nervous system of autoimmune origin (multiple sclerosis, leukodystrophy, leukoencephalopathy, etc.).
• Acute cerebrovascular accidents of ischemic or hemorrhagic type.
• Vascular pathologies of the central nervous system.
• Study of the structure of identified neoplasms.
• Infectious diseases.

There are also a number of symptoms that indicate that an MRI of the brain with contrast is indicated:

• Headaches and migraines.
• Epileptic seizures.
• Cramps.
• Dizziness.
• Impaired sensitivity (tactile, temperature, pain).
• Paresthesia and a tingling sensation on the skin.
• Progressive decrease in visual acuity and hearing.

MRI with contrast is performed to assess the scope of surgical intervention, as it allows for a detailed examination of all the nuances of the future surgical field and its interaction with surrounding structures.

Before conducting diagnostics, the doctor performs allergy tests to determine the body's sensitivity to the contrast agent used. Individual intolerance or allergic reactions to contrast agents and their components is one of the contraindications for MRI with contrast. To eliminate the problem, antihistamines and corticosteroids can be used.

Gadolinium, derivatives of iron-oxygen compounds, and manganese compounds are most often used as contrast agents. When gadolinium enters the intercellular space, it forms weak bonds with hydrogen in water molecules. At the same time, the substance does not penetrate the boundary between the bloodstream and brain cells (the blood-brain barrier), i.e., it does not affect tissue contrast.

Contraindications for MRI of the brain vessels with contrast:

• Individual intolerance to the contrast agent.
• Severe renal failure.
• Impaired renal function.
• Pregnancy in the first trimester.
• Metal implants, pacemakers, pumps and other structures in the patient's body, except for dental pins.
• The patient's weight is more than 120 kg.

After the procedure, breastfeeding should be stopped for 24 hours. There are also a number of relative contraindications:

• Severe cardiovascular failure.
• Myeloma disease.
• Bronchial asthma.

In each case, the decision to undergo examination is made on an individual basis.

During contrast enhancement, the patient may experience hot/cold attacks, an unpleasant taste in the mouth, dizziness, drowsiness, nausea, and the urge to urinate. After some time, the unpleasant symptoms will pass on their own. To reduce the risk of their development, a light meal is recommended before the procedure.

If after the diagnosis there is difficulty breathing, itchy skin rash, pain, burning or a feeling of distension at the injection site, you should immediately inform your doctor. However, the contract does not affect mental activity and the ability to drive a vehicle or other mechanisms.

MRI of the brain vessels without contrast

Magnetic resonance imaging of the brain vessels without the use of a contrast agent is performed to assess the condition of the veins and arteries. The main indications for diagnostics are:

• Stroke (hemorrhagic, ischemic).
• Aneurysms.
• Thrombosis.
• Vascular pathologies.

Non-contrast MRI determines the functional and anatomical features of the bloodstream of the area being examined. The procedure is non-invasive and painless. Radio waves and a magnetic field are used to obtain two-dimensional images of blood vessels. The scan data is read by a tomograph and visualized by a computer.

Diagnostic manipulation without a contrast agent allows us to identify tumors, signs of stroke, pathological changes in brain tissue and blood vessels, and various vascular anomalies.

[ 11 ]

MRI of the head and brain vessels

Layer-by-layer examination of the head and brain vessels using nuclear magnetic resonance is rightfully considered one of the most informative diagnostic methods. The procedure is non-invasive and absolutely painless. High-frequency pulses and powerful magnetic fields are used during scanning. With their help, the computer receives detailed information about the condition and development of vessels and other structures in the area being studied.

Main indications for MRI:

• Suspected brain tumors.
• Cramps.
• Stroke.
• Heart rhythm disturbances.
• Deterioration of memory and vision.
• Injuries.
• Weakness in the limbs.
• Irritability.
• Mental disorders.
• Pathologies of the pituitary gland.
• Rapid fatigue.
• Impaired coordination of movements.
• Lesions of the inner ear.

Magnetic resonance imaging reveals inflammatory processes in the nose, ears, and maxillary sinuses. The procedure is performed with or without a contrast agent. The duration of the diagnostics is no more than 30 minutes.

MRI of the brain and neck vessels

A highly accurate diagnostic manipulation that allows you to get the most objective picture of the state of the brain vessels and neck arteries is tomography. Compared to other studies, MRI has a number of distinct advantages:

• Suitable for patients with hypersensitivity to iodine-containing contrast agents.
• MRI creates a magnetic field and does not use radiation exposure, so the procedure can be performed as many times as necessary during the day/week.
• Examination results in 3D and video format.

Neck vessel scanning is sensitive to blood flow velocity, therefore it allows visualization of blood flow features, structure and functions of the venous bed, vessels and their walls, surrounding tissues. Thanks to this, the doctor receives reliable data on the location of the vessels, their diameter, stratification, obstruction, lumen between the walls.

Indications for MRI of the vessels of the neck and head:

• New growths.
• Anomalies in the size of vessels and veins, their localization.
• Vein fusion.
• Pathologies of the carotid artery.
• Vascular aneurysm.
• Thrombophlebitis.
• Vasculitis.
• Invasion of soft tissue tumors into blood vessels.
• Compression of blood vessels by scar tissue in the postoperative period and after injuries.
• Blood pressure surges.
• Headache and dizziness.
• Fainting and pre-fainting state.
• Sleep and memory disorders.
• Impaired speech, vision, and swallowing.

The procedure is contraindicated for patients with middle ear implants and pacemakers. Relative contraindications include: intravascular stents, pregnancy, somatic diseases in the decompensated stage, metal implants.

MRI angiography of cerebral vessels

MR angiography is a procedure for obtaining two-dimensional images of blood vessels using a magnetic resonance imaging scanner. Features of angiography:

• Diagnosis of the state of the circulatory system.
• Identification of areas with impaired blood flow.
• Localization of stenosis, aneurysms.

The study is aimed at studying the blood vessels of the brain, blood flow in the capillaries, veins and arteries. During the procedure, the lumens of the blood vessels, their walls and surrounding tissues are visualized. The presence of blood clots, atherosclerotic plaques, and wall delamination are determined. If a higher degree of visualization is required, contrast agents are used.

Angiography is prescribed if there is a suspicion of damage to the blood vessels of the brain or cervical spine. The examination allows you to determine the cause of frequent headaches and dizziness, a sharp decrease in hearing and vision. To assess the condition of the blood vessels before neurosurgical operations and to monitor the recovery process.

[ 12 ]

MRI of the vessels and veins of the brain

Magnetic resonance imaging can reveal structural disorders of the brain and its vascular anomalies. The main indications for diagnostics are:

• Tumor neoplasms.
• Strokes.
• Multiple sclerosis.
• Hemorrhages.
• Contusion disorders after injuries.
• Aneurysms.
• Arteriovenous malformations.
• Anomalies along the course of blood vessels.
• Stenosis and occlusion of vessels.
• Atherosclerotic changes.

The examination makes it possible to detect microstrokes at early stages, hematomas, and visualize vascular structures. The procedure is performed with/without contrast. The duration of MRI is about 30 minutes. Based on the scanning results, the patient receives video and images of the area being examined.

[ 13 ], [ 14 ]

MRI of the brain vessels at home

Layer-by-layer examination of organs and tissues using nuclear magnetic resonance is performed in specialized clinics and laboratories. MRI is not done at home, since the procedure is performed on complex equipment that is not adapted to frequent movements in space.

At the same time, there are devices in trailers that are used in hard-to-reach areas or poor countries to save money.

If it is necessary to conduct MRI of the brain vessels for patients who cannot move independently, special vehicles are called. Such vehicles ensure safe transportation, as they are equipped with all the necessary medical equipment.

How long does an MRI of the brain vessels take?

Magnetic resonance imaging takes from 20 to 60 minutes. The duration of the procedure depends on the following factors:

• Scope of the study.
• The need to use contrast agents.
• Number of pathologies and their prevalence.

Before the procedure, the patient informs the doctor about any contraindications. If necessary, a contrast agent is administered. For scanning, the patient is placed on a couch and the head is fixed. This allows avoiding even a slight change in the patient's position due to the risk of obtaining inaccurate and blurred images.

If the patient is nervous before MRI, sedatives or light anesthesia may be used. The results of the examination are ready a couple of hours after scanning. The images and videos are given to the patient or sent to the attending physician. Tomography does not cause harm to health, so it can be performed repeatedly.

MRI of cerebral vessels in children

Childhood patients are predisposed to developing pathologies related to the functioning of the brain. Magnetic resonance imaging is most often used to diagnose them. This method allows detecting the slightest changes in the vessels and other structures of the brain.

Indications for the procedure:

• Recent injuries and concussions.
• Convulsions.
• Frequent headaches and dizziness.
• Periodic fainting.
• Progressive loss of hearing and vision.
• Developmental delay.
• Changes in behavior.

Layer-by-layer examination of vessels using nuclear magnetic resonance allows us to identify cysts, disorders of the pituitary gland or inner ear, hypoxia, ischemia, intracranial hemorrhage, abnormalities in the development of brain structures, and other pathologies.

The diagnostic manipulation does not require special preparation. On the day of the procedure, the baby should not have jewelry or clothes with metal elements. For a high-quality examination, the child must lie still, so a harmless drug is selected to immerse him in a drug-induced sleep. Anesthesia is selected by an anesthesiologist, taking into account existing contraindications and possible reactions to the drug.

The magnetic field does not affect the body of a child or an adult, so it is absolutely safe. A detailed image of the area being studied is formed due to the activation of hydrogen atoms in the cells.

[ 15 ]

Contraindications to the procedure

MR angiography, like any diagnostic procedure, has its contraindications. They are mainly related to the effect of the contrast agent on the body. Based on this, MRI of the brain vessels is prohibited in the following cases:

• Acute mental disorder.
• Severe infectious processes.
• Severe somatic condition.
• Hyperkinesis, epilepsy.
• Pregnancy and lactation.
• Hypersensitivity to contrast agents.
• Inability to lie still for a long time during the procedure.
• Renal failure.
• Claustrophobia.

Since the tomograph operates on the basis of magnetic fields, people with metal implants, heart valves, neurostimulators, dental prostheses, clips on blood vessels, and intrauterine devices are not allowed to undergo MRI.

There are also diseases that in the decompensation stage can disrupt the results of the examination: cardiovascular pathologies, bronchial asthma, severe dehydration. Taking beta-blockers and drugs based on them is an additional contraindication for MRI. People in a state of alcohol or drug intoxication are not allowed to undergo the examination.

[ 16 ], [ 17 ]

Normal performance

The results of magnetic resonance imaging are issued on the day of the examination. The decoding is done by a radiologist. The doctor makes a conclusion, forms the images and videos taken and gives them to the patient or sends them to the attending physician. As a rule, no more than 2 hours pass from the moment of the examination until the results are received.

Decoding the results of MRI of the brain vessels takes place in several stages:

• The MRI machine transmits the results of the examination to a special computer. They are visualized as images of the brain in four projections: front, upper, left, right.
• The resulting images are printed on film and carefully studied on a table with internal lighting. The doctor determines the normal and abnormal values.
• The results of the decoding are presented in the form of a medical report with information about all the tissues examined and their condition, and the presence of deviations.

At the same time, the radiologist does not make an exact diagnosis or develop a treatment plan. This is done by the doctor who issued the referral for tomography.

Interpreting the results of diagnostic manipulation is a complex process, but there are a number of pathologies that can be easily identified in the images:

1. Stroke - due to oxygen starvation, there is an area with hypoxia, which is shown as a light spot on the image. Blood supply in such an area is reduced. If there are ruptures of blood vessels, this is a sign of a hemorrhagic form of stroke. The rupture sites are displayed as dark cavities, which have ring-shaped stripes along the periphery.
2. Multiple sclerosis – the pathology is characterized by the appearance of nerve fibers without a myelin layer. In the image, this is manifested by focal formations. When contrasted, they have a different shade, since they accumulate contrast in different quantities. If the disease is at an early stage, then there are several foci, as it progresses, their number increases.
3. New growths are light spots of asymmetrical shape with uneven edges. At the site of tumor growth, the formation of new vessels and their increased blood supply is observed.
4. Atherosclerosis of blood vessels – the images show atherosclerotic plaques and a noticeable decrease in the lumen of the vessels.
5. Aneurysm – the vessel walls are thinned and dilated. In malformation, the vessels are radially arranged, connecting closer to the center.

If all areas of the brain are within normal limits, then the signal intensity from the MRI device is the same. Thanks to contrast, the state of the vessels is studied in detail, since the contrast agent fills them evenly. If the images are inaccurate or the image is blurred, then a repeat study is carried out.

[ 18 ], [ 19 ]

What does an MRI of the cerebral vessels show?

The diagnostic procedure of MRI of the brain vessels is based on the difference between the signal from static tissue and blood moving in the vessel bed. To improve the clarity of the image, special contrast agents are used (paramagnetic-based drugs, gadolinium).

MRI of the brain vessels shows (visualizes) the anatomical and physiological state of blood vessels. This allows us to evaluate the physical, chemical and biological processes in the brain tissue.

The tomograph provides a three-dimensional image of the blood supply in the required area. This will allow you to isolate individual vessels in the required projection of the brain region being studied. The main indications for examination:

• Cerebral circulatory disorders.
• Blood flow assessment.
• Detection of vessels affected by atherosclerosis, aneurysms, and vascular wall dissections.
• Determination of venous and arterial malformation processes.
• Localization and size of blood clots, hematomas, vascular anastomoses.

The device does not use radiation, which is dangerous for the human body, so the procedure is absolutely safe.

Complications after the procedure

The danger of magnetic resonance imaging is associated with the effect of a magnetic field on the body. Obtaining a layered image of tissues and organs is possible due to the resonance of hydrogen atoms under the influence of a magnetic field. Hydrogen protons change radio frequency pulses, which is recorded by the device's sensors.

According to studies, X-rays are much more dangerous than magnetic resonance. X-rays damage the genetic apparatus and provoke chromosomal abnormalities. And the effect of high doses of X-rays causes acute radiation sickness. MRI excludes such disorders.

The consequences after the procedure are related to the violation of preparation for the examination. Thus, any metal implants in the human body are set in motion under the influence of magnetization. Because of this, their movement leads to damage to soft tissues. When using contrast, there is a risk of pinpoint hemorrhages and increased permeability of the arteries. There is also a risk of allergic reactions to ballast compounds in the contrast.

Allergic reactions to contrast are the most common complication after an MRI procedure. Injections of contrast material can cause the following disorders:

• Embolism is a blockage of blood vessels by air.
• Infectious infection (sepsis, shock, phlebitis).
• Local inflammatory reactions when administering drugs outside the vein.

It is also possible to develop breathing problems, tachycardia, urticaria. But with proper preparation for the examination, the risk of developing such complications is minimal.

Care after the procedure

There are no special actions or care required after undergoing an MRI. The patient changes into his/her clothes and continues with his/her day. There are no restrictions regarding behavior after the examination. That is, patients can maintain normal activities immediately after the MRI.

Reviews

MRI of the brain vessels has many positive reviews confirming the effectiveness, diagnostic accuracy and value of the procedure. The study allows you to identify the smallest deviations and anomalies in vascular structures. It makes it possible to assess the state of the bloodstream, diagnose serious pathologies at the early stages of their development. The results of the study allow you to make a timely treatment plan for life-threatening pathologies.
