CT Arthrography (Any Joint)

SJRA Imaging Services

CT arthrography uses computed tomography (CT) scanning to generate high-resolution images of the inside of a joint (e.g., shoulder, knee, wrist, ankle) to evaluate joint abnormalities and to help diagnose unexplained joint pain.  In direct arthrography, a contrast material (dye) is injected directly into the joint. In indirect arthrography, the dye is injected into the bloodstream.

Preparing for a CT arthrography:



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 >81mg/day – seven days
  • Plavix, Ticlid or Dipyridamole – seven days
  • Coumadin (Warfarin) – five days and repeat PT-INR
  • Cilostazol (Pletal) – two to three days
  • Naproxin (Aleve) – two to three days
  • Ibuprofen (Motrin, Advil) – 24 hours
  • Lovenox 2x/day – two doses
  • Heparin IV GTT – two hours prior to the study

If you have 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 (e.g., Medrol) and Benadryl (OPTIONAL) and must be started 24 hours prior to your study.

All of our centers are fully accredited by the American College of Radiology.
