Information for People Undergoing MRI Examinations

MRI is a safe examination without any radiation. Patients do not need to prepare for most of the examinations. However, because of the strong magnetic field in the scan room, certain conditions may preclude you from having an MRI examination. Please alert our staff if one or more of the following conditions may be applicable to you.

• Pacemaker

• Pregnancy
• Claustrophobia

• History of renal failure
• Tattoos or permanent cosmetics

• Neurostimulator

• Vascular clips

• Metal implants for artificial joints or orthopedic surgery
• Any metal foreign body in the body especially the orbits

• Shrapnel or bullet wounds
• Dentures

• History of MRI contrast allergy

After a thorough pre-scan evaluation, our staff will notify you if you can have the examination. If necessary and possible, we may modify the scanning protocol for your special conditions.


For contrast study, there is no need to fast prior to the examination.


For MRCP, patient should cease eating and drinking at least 4 hours prior to the examination.
