If you have a pacemaker you cannot have an MRI because the test may damage it.

If you have metal fragments in your eyes you may not be able to have an MRI because the test may injure your eyes.

No special preparation is needed before an MRI scan. You may eat normally and take your usual medications. If you are having a scan of the lower body (pelvis or abdomen), you will be asked not to eat or drink for about five hours before your appoinment.

Wear loose, comfortable clothing without metal fastenings such as zippers or clasps because metal will interfere with the test (don't forget metal underwire bras). Please do not wear jewelry i.e. Earrings, necklace, watches, bracelets, etc.

Tell the doctor if you have any metal in your body (such as plates, surgical clips, certain artificial heart valves or screws from a previous surgery).

Dental fillings and bridges, hip and knee replacements and tubal ligation clips are not a problem. Ask the radiologist if you are in doubt.
