How you prepare

Clothing and personal items

An MRI uses a magnetic field to create detailed pictures of the inside of your body. Metal objects on — or in — your body may interfere with the magnetic field used during the exam, affecting the quality of the MRI and possibly causing a safety problem. The magnetic field may also damage electronic items.

If possible, leave jewelry or metal or electronic accessories at home, as you'll be asked to leave these items in the dressing room before the procedure.

Tell the technologist if you have any metal or electronic devices inside your body, such as metallic joint prostheses, artificial heart valves, implanted electronic devices, cochlear implants, body piercings or dental implants.

Other precautions

The day of treatment you'll need to shave your lower abdomen between your pubic bone and bellybutton.
