Provides high resolution images of the brain and/or cranial nerve distributions through your face and neck.

When you arrive for your examination, you will be asked to fill out a safety questionnaire.

You will lie on the scanner and a special coil will be placed over your head to help obtain the images. For all Brain, Skull Base or Nasopharynx imaging, you will enter the scanner head first. You will go into the scanner until your head is in the centre of the scanner, from your waist down should remain out of the scanner.

A small mirror is positioned above your head which acts like a periscope. This gives you the feeling of spaciousness and allows you to see out of the scanner. You will be given headphones or earplugs and a buzzer to press if you want to talk to the technologist at any time. The scan is noisy, but all you have to do is lie still.

On some occasions, a contrast dye (gadolinium) may be required. If this is required the technologist will explain the process. The contrast dye will be administered through a small needle (intravenous cannula) that will be placed in your arm.

Before your Scan

No preparation is required.
