MR imaging of sports injuries of the hip.

While MR imaging studies of the hip have been directed routinely toward the diagnosis of atraumatic osteonecrosis (ON), interest has increased in the use of MR imaging to diagnose other disorders of the hip and surrounding soft tissues, especially in athletic injuries. In addition to reviewing MR imaging technical considerations and image appearance, this article discusses applications of MR imaging to diagnosing pelvic and hip fractures, muscle contusion and strain, tendon injuries, acetabular labral tears, bursitis, and osteitis pubis and chronic symphyseal injury.
