Magnetic Resonance Imaging
Preparing for your MRI scan
Safety
The most important part of preparing for your MRI is determining whether you have any metal or surgical implants that may be affected by the strong magnetic fields used in the MRI process. Most implants are not affected by MRI, but if you have any of the following, please contact us:
- pacemaker
- aneurysm clips
- cochlear implant
- recent surgery in the past 6 weeks
- pregnant
- history of any eye injury involving metal fragments
Other implants like artifical hips, orthopedic pins, etc. may cause some image distortion if located in the area your doctor wants us to scan, but otherwise pose no risk to you or your MRI. The same pertains to dental work.
Other preparations
- There are no specific dietary or other preparations for your MRI scan. Take your medications as usual.
- Scented products (perfume, cologne, after shave, aromatherapy, hair spray, etc) may cause allergic reactions, including severe respiratory distress, in those with sensitivities. For the safety of our staff and other patients we ask that you do not apply any scented body products on the day of your appointment.
- You have the option of changing into hospital clothes upon arriving for your appointment, or you can wear clothes with no metal snaps, pins, or zippers. Those patients for whom changing clothes presents difficulties may wish to arrive already wearing metal-free clothes.
- You can bring your own CDs or audio tapes, or choose a radio station to listen to during your MRI scan. You do not need to bring your own radio or playing device. We have a special MR-compatible sound system.
- Some patients may be anxious about lying in the MRI scanner. Normally sedation is not necessary, but if you know that you suffer from claustrophobia, e.g., you cannot ride in elevators or airplanes, you may prefer to take some mild sedation before your MRI examination. You must arrange a prescription for sedation from your own doctor prior to your MRI appointment. The UBC Hospital MRI department does not dispense sedatives. If you are planning to take sedation, please have someone accompany you, or plan to use public transportation or a taxi. Our departmental policy defines that you must not drive after taking sedation.
- If you have not been out to the UBC campus before, please allow ample travel time to ensure that you arrive on time for your appointment.
