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. ⋯ 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.

ReviewClinical applications of magnetic resonance contrast media in the head.
The clinical utility of paramagnetic metal ion chelates for contrast enhancement in MRI of the brain is well established. Contrast administration provides both improved sensitivity and specificity with respect to diagnosis in neoplasia, infection, demyelinating disease, infarction, and arteriovenous abnormalities. On the basis of results from prospective studies, use of enhanced scans, in addition to baseline precontrast T1- and T2-weighted scans, is advocated in all patient studies in which there is a high index of suspicion with respect to intracranial pathology.

Magnetic resonance imaging of pediatric atraumatic musculoskeletal lesions.
MRI has become a useful study for evaluating the musculoskeletal system. This article discusses the technique of pediatric musculoskeletal MRI and its practical applications. MRI appearances of various pathologic entities, including infection, neoplasms, marrow disorders, and joint diseases, are also reviewed.
