Arthrography is a medical imaging technique that takes pictures of joints such as the shoulder or knee. It involves injecting dye (contrast media) into the joint to help the doctor see in greater detail. The imaging may be done by X-ray, CT scan, MRI, or fluoroscopy.
An arthrogram may be performed to look for causes of pain, loss of motion, or changes in the joint function, which might include soft tissue tears in the joint.
