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 to know that MRI of the brain is used to examine both soft tissues and blood vessels for damage or injury, such as a stroke.

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.

Sometimes, MRI diagnosis may be required to confirm or refute the diagnosis.

If:

– disturbed by constant or acute headaches;

– There is a constant or periodic noise in the ears

– there is weakness and numbness in the extremities;

– there is a deterioration of memory;

Occasionally, fainting can occur

– The person is confused;

– There was a craniocerebral injury.

You need to determine the cause of seizures.

Contrast-enhanced MRI of the brain

In order to see the brain more clearly, a contrast is used, which is introduced into the human body. The dye can be used to diagnose tumors and other diseases, as well as their structure and contours.

Contraindications to use

MRI of the brain is the safest procedure, but some people do not do it: if they have a pacemaker, a hemostatic clip in the brain or metal implants.

It is also worth giving up MRI when:

– pregnancy;

– claustrophobia;

– the presence of cochlear implants;

– Decompensated Heart Failure

– The presence of tattoos that are made from metal;

Installed crowns and braces

How is the MRI examination

The preparation is the first step in the examination. It is important to take out all metal objects from the phone and then remove it.

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.
