In the context of pediatric cross-sectional imaging, the risk of ionizing radiation for CT and the potential adverse effects associated with sedation/anesthesia for MRI continue to provoke lively discussions in the pediatric literature and lay press. This is particularly true for issues relating to the risks of ionizing radiation for CT, which has been a topic of discussion for nearly two decades. In addition to understanding these potential risks and the importance of minimizing individual pediatric patient exposure to ionizing radiation, it is equally important for radiologists to be able to frame these risks with respect to the potential for adverse outcomes associated with the use of anesthesia for cross-sectional imaging in the pediatric population. Notably, before such risks can be estimated and compared, one should always consider the potential utility of each imaging modality for a given diagnosis. If one cross-sectional imaging modality is likely to be far superior to the other for a specific clinical question, every effort must be made to safely image the child, even if sedation/anesthesia is required.
在儿科横断面成像中，CT 检查的电离辐射风险以及 MRI 检查中镇静/麻醉相关的潜在不良影响在儿科文献和大众媒体中持续引发激烈讨论。这对于与 CT 检查的电离辐射风险相关的问题尤其如此，这个问题已经讨论了近二十年。除了了解这些潜在风险以及尽量减少个别儿科患者接受电离辐射的重要性之外，放射科医生同样重要的是能够根据儿科人群中使用麻醉进行横断面成像相关的不良后果的可能性来框定这些风险。值得注意的是，在评估和比较这些风险之前，人们应该始终考虑每种成像方式在特定诊断中的潜在效用。如果一种横断面成像方式对于特定的临床问题可能远远优于另一种，那么必须尽一切努力安全地对患儿进行成像，即使需要镇静/麻醉。
