When is this performed?
- Magnetic Resonance Imaging (MRI) is requested by an endocrinology specialist in the investigation of a variety of disorders.

Are there any side-effects?
- This scan does not use radiation, like x-rays and CT scans
- Usually none
- The scan is painless
- Some patients may rarely react to the dye
How long does the test take and is admission to hospital required?
- The procedure may take 15-40 minutes, depending on the area being scanned, and does not usually require admission
What should you tell your doctor?
- If you have a pacemaker, joint replacement or any other metal items in your body
