Cranial MRI examination

With a cranial MRI scan, the brain can be examined, the grey and white matter, the cerebral ventricles and the blood vessels can be clearly seen. MRI is an imaging diagnostic procedure that uses magnetic field to take detailed images of the human body. Due to the magnetic field generated by the device, the energy changes in the body are converted into a high-resolution, three-dimensional image by a high-performance computer.

What kind of preparation is required?

In all cases, it is recommended that you consult your doctor about the details before having an MRI scan. Native examination does not require special preparation. On the other hand, it is important to know that due to the high magnetic field, it is forbidden to bring any metal, device or object containing metal into the examination room! This also applies to jewellery and piercings in the body.

Are there any side effects of the test?

Cranial MRI has no side effects.

Rarely, the contrast agent may cause a reaction. In the case of pre-existing known allergies, no examination with contrast agent is performed.

How is a cranial MRI scan performed?

During the examination, the patient most often lies on their back, with the exception of a few cases where the MRI is focused on the abdomen. Recordings are usually made with sequences that vary in three levels. The examination is noisy, a strange, knocking, machine noise can be heard. Its intensity can be reduced by using earplugs.

When can the test not be performed?

If there is any magnetically responsive material in your body, such as a prosthesis, nail, screw, metal valve, pacemaker, tourniquet, implant, etc. These can move out of place during the examination in a strong magnetic field and, in severe cases, can cause injury and make the scan invaluable.

Medicover’s MRI device is called a closed machine, so the patient may feel confined. However, the good news is that this can be mitigated by the fact that the machine’s diameter is larger than average with its 70 cm. If the patient is prone to claustrophobia, the test may be difficult to be performed.

When is the result expected?

The completed recording will be reviewed by the radiologist and the result will be available in our online system after 3 working days.
