An arthrogram is a diagnostic test using X-ray contrast in order to see what is wrong with a joint. The iodine serves as a contrast medium that helps your doctor see joint problems that are causing pains.
In addition to helping your doctor examine your joints, an arthrogram may be used to look at how ligaments, tendons and cartilage and how they are working inside your body. An arthrogram can help your doctor evaluate the need for joint replacement procedures. The test can be used to look at joints and tissue in the ankle, wrist, shoulder, hip and knee.
Preparation before the procedure
Tell your doctor before the test if there is any chance you are pregnant or if you are allergic to iodine.
