Magnetic resonance imaging (MRI) of the brain

Magnetic resonance imaging (MRI) of the brain is one of the most accurate and informative studies in modern diagnostics. MRI allows for a detailed assessment of the structure of the brain, blood vessels, and surrounding tissues, which is a prerequisite for the timely detection of many neurological diseases.

The study does not use ionizing radiation and uses a strong magnetic field and radio waves to create high-quality images. This is why MRI is particularly effective in diagnosing pathologies that are not always fully visible on computed tomography (CT).

Brain MRI - what does the study include?

MRI is a non-invasive test that allows the doctor to assess in detail:

• Different areas of the brain - their structure, symmetry, and changes that may be associated with various neurological diseases, trauma, or other pathologies.
• The ventricular system of the brain - the size, shape and condition of the ventricles, which is important, for example, for assessing hydrocephalus and cerebrospinal fluid circulation disorders.
• Blood vessels - the structure and condition of blood vessels, which helps to detect pathologies such as aneurysm, vascular malformation, or circulatory disorders.
• Pathological changes within the skull - including tumors, inflammatory processes, hemorrhages, cysts, and other changes that may affect brain function.

The study is used both for the initial detection of the disease, as well as for monitoring an already established diagnosis and assessing the effectiveness of treatment.

When is a brain MRI prescribed?

Magnetic resonance imaging of the brain is prescribed when a detailed assessment of the brain and nervous system is needed. The study helps the doctor both in diagnosing various diseases and in assessing the course and results of treatment of already established pathologies.

A doctor may order a brain MRI if the patient has:

• Severe, prolonged or recurring headache;
• Dizziness or loss of balance;
• Loss of consciousness;
• Convulsive episodes;
• Sudden or progressive loss of vision or hearing;
• Speech difficulty or other neurological symptoms;
• Numbness, tingling, or weakness in the limbs;
• Impaired movement coordination;
• Head injury;
• Suspected stroke or other acute neurological condition.

Brain MRI is also used to monitor already diagnosed neurological diseases and to assess the effectiveness of treatment.

What diseases can a brain MRI detect?

Brain MRI is used to diagnose various neurological, vascular, infectious, and oncological diseases.

Magnetic resonance imaging of the brain can detect:

• Brain tumors - their localization, size and relationship to surrounding tissues;
• Stroke - both acute and past ischemic or hemorrhagic changes;
• Multiple sclerosis - characteristic lesions of the central nervous system;
• Aneurysms and vascular malformations - structural changes in blood vessels;
• Hemorrhages and traumatic injuries - to detect hemorrhages and other brain injuries resulting from trauma;
• Inflammatory and infectious processes - which damage the brain or its membranes;
• Congenital anomalies - for the assessment of congenital disorders and anatomical features of brain development;
• Hydrocephalus - changes caused by the accumulation of fluid in the ventricular system of the brain.

How is the scan performed?

Before the examination, the patient removes all metal objects, after which he lies on the moving table of the tomograph.

The table moves slowly through the scanner tunnel. It is important for the patient to remain completely still during the procedure, as movement can affect the quality of the images.

During the examination, the device emits characteristic sounds; to avoid this discomfort, the patient will be given special headphones or ear protectors.

In some cases, the study is performed using a contrast agent, which is injected into a vein. This helps the doctor evaluate organs and tissues in more detail.

The duration of the scan depends on the area being examined and the type of scan, but is usually 15-45 minutes.

How to prepare for an MRI scan?

In most cases, no special preparation is required for the study.

However, before the test, it is important to tell your doctor if:

• You have a pacemaker;
• You have a metal implant in your body;
• You are pregnant or suspect you are pregnant;
• You have previously had an allergic reaction to contrast material.

If a contrast study is planned, the doctor may also make additional recommendations.

Siemens MAGNETOM Vida 3T - high-precision tomograph at Bochorishvili Clinic

At Bochorishvili Clinic, brain MRI is performed using the Siemens MAGNETOM Vida 3T tomograph, which is a state-of-the-art 3-Tesla magnetic resonance tomography.

The advantages of the device are:

• 3-Tesla high magnetic field, which provides high-quality images;
• BioMatrix Technology adapts to each patient's individual anatomy;
• Fast scanning modes reduce examination duration;
• Artificial intelligence-based technologies help improve image quality and optimize the workflow;
• A 70 cm wide tunnel creates greater comfort for the patient, especially for those who suffer from claustrophobia;
• Integrated video screen where the patient can watch the desired video during the examination process;
• An orthopedic mattress reduces discomfort during long examinations.

These technologies are especially important when it comes to accurately assessing small structural changes in the brain.

What is the difference between a brain MRI and a CT scan?

Magnetic resonance imaging (MRI) and computed tomography (CT) of the brain are studies based on different principles, and each has its own purpose.

MRI uses a strong magnetic field and radio waves to produce highly detailed images of the soft tissues of the brain. It is particularly effective in evaluating tumors, inflammatory diseases, epilepsy, chronic vascular changes, and other neurological pathologies.

CT uses X-rays and the examination process is relatively shorter than MRI, which is why it is often the first choice in emergency situations, such as when evaluating head trauma, acute hemorrhage, or skull fractures.

If a detailed assessment of the soft tissues of the brain is needed, MRI is preferred in most cases. However, the doctor will determine which study is necessary in a particular case based on the patient's symptoms and the purpose of the study.

Conclusion

Brain MRI is one of the most reliable studies when a detailed assessment of the brain and nervous system is needed. Timely examination often plays a crucial role in the early detection of neurological diseases, as well as in assessing their course and treatment outcomes.
