In this imaging scan, contrast enhanced computed tomography is used to create cross-sectional images of the pelvis/hip bones. Your doctor may advise this test if you are suffering from pain in the groin area, experiencing limping, stiffness, or radiating pain to the right leg. The test helps diagnose various disorders of hip joints such as fractures, femoroacetabular impingement, bone tumours, calcified intra-articular bodies, and arthritis.
