MRI Preparation

Because the strong magnetic field used for MRI may affect certain metallic objects and electronic devices implanted in the body; our MRI staff will ask whether you have any of the following:

  • Heart pacemaker or artificial heart valve
  • Aneurysm clip in the brain
  • Intrauterine Device (IUD)
  • Prosthetic joints such as hip or knee replacement
  • Implanted vascular port (brand names Port-o-cath, Infusaport, Lifeport)
  • Any metal plates, pins, screws, or surgical staples

You will be asked to remove anything that might degrade MRI images of the head, including hairpins, jewelry, eyeglasses, hearing aids, and any removable dental work. Dyes used in tattoos and permanent eyeliner may contain metallic iron oxide and could, in rare circumstances, heat up during MRI.

The radiologist or technologist may ask if you have any drug allergies and whether you have undergone any surgery in the past. If you are or might be pregnant, mention it to the MRI staff.
