MRI of the brain is one of the modern non-contact methods of brain research, which uses a magnetic field and radio waves that transmit a signal to a computer and allow you to assess the state of the brain. It is important that MRI of brain can be used to assess the health and condition of both soft tissues as well as blood vessels.
When is an MRI scan done?
An MRI of the brain can be used to confirm or detect a variety of diseases. During an MRI examination, the doctor can see a detailed image of your brain and assess its condition.

Contrast-enhanced MRI (MRI) of the brain
In order to see the brain more clearly, a contrast is used, which is introduced into the human body. Thanks to the introduction of the dye, tumors and other pathological formations can be diagnosed, and their size, structure and contours can be studied in more detail.
Contraindications to use

What is an MRI exam?
The examination begins with the preparation: it is necessary to remove all metal objects and remove the phone.
After the patient is placed on the table, and a device is fixed on the head, which will send and receive radio waves. MRI is performed for 30-60 minutes, depending on the department and the presence of contrast in the body.
The doctor receives many layer-by-layer images of the brain, on the basis of which he makes a conclusion and confirms or denies the diagnosis.
