MR arthrogram is a noninvasive medical procedure that uses a magnetic field and radio frequency energy to evaluate joints, identify abnormalities, and help identify the cause of unexplained joint pain. This exam does not use ionizing radiation. It may require an injection of a contrast material.
Preparing for an MR arthrogram:
BEFORE STOPPING ANY MEDICATION PLEASE CHECK WITH YOUR PHYSICIAN.
Do NOT eat or drink anything three hours prior to your procedure.
If you are taking any anti-coagulants, please contact your physician about withholding that medication for the specified time period prior to your exam:
- Full-dose aspirin greater than 81 mg/day – seven days
- Plavix, Ticlid or Dipyridamole – seven days
- Coumadin (Warfarin) – five days and repeat PT-INR
- Cilostazol (Pletal) – two to three days
- Naproxen (Aleve) – two to three days
- Ibuprofen (Motrin, Advil) – 24 hours
- Lovenox 2x/day – two doses

If you previously experienced a MILD allergic reaction to IV dye (e.g., hives, itching), you MUST contact your doctor to obtain a prescription for a steroid prep; this prep consists of methylprednisolone (Medrol) and Benadryl (OPTIONAL) and must be started 24 hours prior to your study.
