Preparations for MRI

  • Some MRI exams may require you to receive an injection of contrast through an intravenous (IV) line.
  • The radiologist or technologist may ask if you have allergies of any kind.
  • Women should always tell their physician or technologist if there is any possibility that they are pregnant.
  • If you have claustrophobia or anxiety, you may want to ask your physician for a prescription for a mild sedative. If you take a mild sedative, you may want to arrange someone to drive you home afterward.
  • Jewelry and other accessories should be left at home if possible.
  • Bring all prior mammograms, breast ultrasounds, and breast MRIs if these tests were performed at a facility outside of Mountain States Health Alliance. In most cases, MRI is safe for patients with metal implants, except for a few types.

People with the following implants cannot be scanned and should not enter the MRI area:

  • internal (implanted) defibrillator
  • cochlear (ear) implant
  • clips used on brain aneurysms

You should tell the technologist if you have medical or electronic devices in your body, such as:

  • artificial heart valves
  • implanted drug infusion ports
  • infusion catheter
  • intrauterine device (IUD)
  • implanted electronic device, including a cardiac pacemaker
  • artificial limbs or metallic joint prostheses
  • implanted nerve stimulators
  • metal pins, screws, plates or surgical staples

In general, metal objects used in orthopedic surgery pose no risk during MRI. However, a recently placed artificial joint may require the use of another imaging procedure. If there is any question, an X-ray may be taken to detect metal objects.
