What It Is
An arthrogram is an x-ray test that uses contrast material to examine a joint. The contrast material is administered directly into the joint space. By use of the contrast material, the physician can see the soft tissue structure of the affected joint, such as tendons, ligaments, muscles, cartilage, and the joint capsule. Arthrograms can uncover the cause of persistent pain, swelling, or abnormal movement within a joint. An MRI or CT-Scan typically follows, depending on what the physician thinks is necessary.
