The presence of metal in your body may be a safety hazard or affect a portion of the MRE image. Before receiving an MRE, tell the technologist if you have any metal or electronic devices in your body, such as:

  • Metallic joint prostheses
  • Artificial heart valves
  • An implantable heart defibrillator
  • A pacemaker
  • Metal clips
  • Cochlear implants
  • A bullet, shrapnel or any other type of metal fragment

Before you schedule an MRE, tell your doctor if you think you're pregnant. The effects of magnetic fields on fetuses aren't well-understood. Your doctor may recommend choosing an alternative exam or postponing the MRE.
