Despite the infrequency of CSI among children without suggestive symptoms or signs, many clinicians have a low threshold for obtaining imaging studies to avoid the potentially serious and costly consequences of missing a CSI. However, the liberal use of imaging must be balanced against considerations of use, radiation exposure, and cost. Unfortunately, limited data exist to inform clinical decision-making regarding the need for diagnostic imaging for the evaluation of CSI in children. Most of the literature in this area has been retrospective in nature, and the … Address correspondence to Mark I.
