Advanced pediatric joint imaging.

Rapid changes are occurring in the field of diagnostic imaging of pediatric joint pathology. CT and ultrasonography have revolutionized imaging, which had previously used only plain film technology. Intravenous sedation administered in the radiology department has facilitated studies that previously were considered impractical or feasible only with general anesthesia. MR imaging shows great promise in replacing certain arthrographic studies, as well as providing important information that has been available only by surgical exploration. Imaging joint disease in the pediatric age group is particularly challenging and at times difficult, but the critical information frequently obtained from these examinations justifies this special effort.
