Magnetic resonance imaging of ankle injuries.

Stress placed on the ankle from sport activity predisposes it to a variety of injuries. MRI, with its multiplanar capability and excellent soft tissue contrast, is uniquely suited for examining the complex anatomy of the ankle. It is the procedure of choice for imaging suspected tendon and cartilage damage. It is also highly sensitive in detecting radiographically occult bone injuries. This review first addresses technical factors important in generating high-resolution images that are crucial for accurate diagnosis in this area. Pathogenesis and MRI appearance of commonly encountered sport-related soft tissue and bone injuries around the ankle are presented and discussed.
