It is a painless imaging technique that uses a rotating beam of X-rays to create cross-sectional images of the right wrist. The scan helps visualize the bones, joints, and the surrounding soft tissues of the wrist. Your doctor may advise this test to diagnose problems such as fractures, deformities or abnormal growth of the bones, arthritis, infection, and osteoporosis. It is also useful in guiding a surgeon to the right area during a biopsy.
