Cranial magnetic resonance imaging is an advanced imaging technique, giving detailed and clear images of abnormalities of the brain, especially brain tumors. In fact, magnetic resonance imaging of the brain is widely used in the diagnosis of neurological diseases. This is something fast, accurate imaging methods fail to diagnose with many previous devices.

1. What is a cranial MRI?

MRI (Magnetic resonance imaging): A non-invasive diagnostic imaging test that uses a system of high-powered magnets, radio waves, and a computer processor to create images of the organs.
Accordingly, cranial MRI is a non-invasive test that uses an MRI machine system to reconstruct brain images, thereby studying normal or abnormal anatomical structures of intracranial structures.

2. What is the MRI of the brain for?

Cranial MRI is used to study normal or abnormal structures of the brain, skull, maxillofacial bones, and soft tissues.
Based on the principle that each organ, part or anatomical structure has a different number and distribution of hydrogen atoms, through computer analysis of different signal changes of organs organs, regions, parts... The radiologist will make an imaging diagnosis of the organ.

3. When to have a cranial MRI?

Today with the advancement of science and technology, so there are many generations of magnetic resonance machines with different magnetic forces (magnetic resonance imaging machines 3.0Tesla, 0.5T, 1.0T, 1.5T, etc.) 2.5T...) and is applied more and more widely in disease diagnosis with increasingly broad indications for many different diseases.
Indications for cranial MRI with the following subjects:
Injury to the blood vessel demage. Brain tumor. Injury to the brain (injury). Multiple sclerosis. Brain stroke (stroke) Diseases of the ear, nose and throat (otitis media ...), eyes, maxillofacial... Vestibular diseases, migraine, headache ...

4. Pros and cons of cranial MRI?

4.1. Advantages of Brain MRI It is non-invasive and does not use X-rays. Does not involve radiation. Magnetic contrast agents rarely have side effects, rarely have allergic reactions. Contrast, sharpness and detail of organs images are very good. Structures can be evaluated in many different directions or in any direction of the brain. The imaging field can be expanded to assess the spread and metastasis of the tumor. In addition, cranial MRI also has many different pulse sequences to help evaluate in detail the structure, limits... even the chemical structure of the lesion (MRI spectro), evaluate the functional area. of the brain (MRI function)...

4.2. Disadvantages of cranial MRI High cost. Loud noise when shooting. It is not always possible to accurately assess the healing or malignancy of a lesion.

Patients with fear of the dark - closed spaces, implanted devices (ear electrodes, intracranial electrodes, pacemakers..), metal fragments in the body (especially in the eye sockets) have may be contraindications to magnetic resonance imaging.
Thanks to the advantages that cranial magnetic resonance brings, now Vinmec International General Hospital has applied magnetic resonance technology to medical examination and treatment, imaging diagnosis. In particular, the cranial magnetic resonance imaging technique at Vinmec is performed methodically and in accordance with the standard procedures by a team of highly skilled doctors and nurses, with modern and standard machinery systems, thus giving the best results. accurately, contributing significantly to the identification of disease and disease stage, diagnosis and screening of cancer pathologies. From there, come up with the most effective treatment plan for the patient.
