Arthrography is a diagnostic tool performed in conjunction with MRI, CT or X-ray to evaluate joints, including hips, wrists, ankles, shoulders, knees, etc. This includes a contrast medium injection into the joint that enhances the visualization of structures and aids the evaluation of joint abnormalities, such as cartilage tears and other injuries.
The procedure is most often used to identify abnormalities within the: shoulder, elbow, wrist, hip, knee and ankle and is often used to help diagnose persistent, unexplained joint pain or discomfort. In some cases, local anesthetic medications or steroids may be injected into the joint along with the contrast medium. These medications may temporarily decrease joint-related pain or inflammation and provide physicians additional information about possible sources of pain.
