MRI/MRA Exam Prep

MRI uses a very powerful magnet, radio waves and a sophisticated computer system to produce remarkable images without x-ray radiation.

  • Before your MRI exam, remove all accessories including hair pins, jewelry, eyeglasses, hearing aids, wigs, dentures. During the exam, these metal objects may interfere with the magnetic field, affecting the quality of the MRI images taken.
  • Notify your technologist if you have:
    • any prosthetic joints – hip, knee
    • a heart pacemaker (or artificial heart valve), defibrillator or artificial heart value
    • an intrauterine device (IUD),
    • any metal plates, pins, screws, or surgical staples in your body.
    • tattoos and permanent make-up.
    • a bullet or shrapnel in your body, or ever worked with metal.
    • if you might be pregnant or suspect you may be pregnant.
    • if you are claustrophobic. Some patients who undergo MRI in an enclosed unit may feel confined. If you are not easily reassured, a sedative may be administered.
  • If you have a history of working around metal, grinding, welding or you think you may have metal in your eyes, you will need to come for an orbital x-ray prior to your appointment.
  • In addition, please do not wear hairspray or eye makeup.
