Magnetic resonance imaging of tendon and ligament abnormalities: Part II. Pelvis and lower extremities

Abstract

Magnetic resonance imaging (MRI) has provided an ideal means, unmatched by other preexisting modalities, of examining musculoskeletal abnormalities, particularly those involving tendons and ligaments in the lower extremities. Lack of motion artifact, convenience of application of surface coil, and absence of overlying structures have made the lower extremities ideally suited to MRI. In addition, the abundance of adjacent adipose tissue provides a superb contrast background. Although evaluation of trauma remains the most common reason for MRI examination, many other conditions may also affect tendons and ligaments. As in other soft-tissue, chondral, and osteochondral lesions, MRI provides exquisite details of abnormalities in these structures. Part II of this review systematically reviews the abnormalities of tendons and ligaments in the pelvis and lower extremities.
