A substantial increase in computed tomography (CT) scanning with availability of state-of-the-art multidetector-row CT scanners has generated debate about its safety and considerable interest in formulating clinical and technologic strategies to reduce radiation exposure. This review describes the magnitude of radiation exposure associated with CT scanning and projected radiation risks as well as clinical strategies and major technologic innovations for reducing radiation dose to patients undergoing CT scanning.
随着先进的多层螺旋CT扫描仪的普及，计算机断层扫描（CT）的使用量大幅增加，这引发了关于其安全性的讨论，并激发了人们对制定临床和技术策略以减少辐射暴露的浓厚兴趣。本综述描述了与CT扫描相关的辐射暴露程度和预计的辐射风险，以及为接受CT扫描的患者降低辐射剂量的临床策略和主要技术创新。
