This article discusses the neuroradiologic characteristics of central nervous system infections in children. These disorders are divided into two groups: those of congenital infections and those of infections in the infant and child. ⋯ The heterogeneous etiologies often can be suggested by the neuroradiologic findings, as demonstrated with computed tomography and magnetic resonance imaging. This article also addresses the sequelae of destructive brain 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. ⋯ 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.
