Magnetic resonance imaging of knee ligaments.

ABSTRACT

Magnetic resonance imaging is a noninvasive and nonionizing imaging modality that has made a significant contribution to our understanding of musculoskeletal injury. With technological advances, sequences have become more accurate and valuable in providing information for the clinician. This information often can guide diagnosis and treatment. The decision to use MRI technology over other modalities is based on cost, availability, information required, and observer interpretation. The risk exists, however, for abuse of this expensive technology at a time when health-care dollars are becoming more scarce. It should never be used as a substitute for sound clinical judgment in the form of careful history taking and thorough physical examination. Also, it should be used when a patient management or intervention will be altered based on the information obtained. The future management of knee ligament injury undoubtedly will be shaped by MRI and its related technologies.
