The modern non-contact method of brain research is MRI of the Brain. It uses radio waves and a magnetic field to transmit a signal to the computer that allows you to assess the brain’s state. 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.
Sometimes, MRI diagnosis may be required to confirm or refute the diagnosis.
MRI should be performed 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 decline in memory.
– fainting occurs periodically;
– the person is disoriented;
– There was a craniocerebral injury.
You need to determine the cause of seizures.
Contrast-enhanced MRI of the brain
Contrast is used to better see the brain. It is introduced into the 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.
Also, it is worth quitting MRIs when:
– pregnancy;
– claustrophobia;
– the presence of cochlear implants;
– Decompensated Heart Failure
– The presence of tattoos that are made from metal;
– installed crowns or braces.
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 has been placed on the table, a device that sends and receives radio waves is attached to the head. Depending on the area and whether there is contrast, MRI can take between 30-60 minutes.
The doctor takes many layers-by-layer photographs of the brain and then makes a decision.
