When scheduling your appointment, you will be asked if you have any metal objects in your body, since the metal may interfere with the magnetic field. MRI cannot be performed on people with:
- Cardiac pacemakers or defibrillators
- Some brain aneurysm clips
- Metal fragments in the eye (plain film X-rays will be done of the orbits if there is prior history of a metallic foreign body)
If you are having a scan of the head, we recommend that you do not wear heavy eye makeup as the metal particles in the makeup may interfere with your exam. You may follow your normal diet and take any medications in your usual fashion. As with any medical procedure, be sure to inform your physician or the technologist if there is any possibility that you are pregnant or if you have a history of allergies.
