尽管人们普遍认为计算机断层扫描 (CT) 在用于适当适应症时会给患者带来极大益处，但由于 CT 在医学中的使用呈指数级增长，人们对 CT 诱发癌症的潜在风险提出了担忧。保持辐射剂量尽可能低，与诊断任务一致，仍然是降低这种潜在风险的最重要策略。本文总结了 CT 辐射剂量管理常用的一般技术策略。特别讨论了儿科CT、心脏CT、双能CT、CT灌注和介入CT的剂量管理策略，并提出了CT剂量减少的未来展望。
Despite universal consensus that computed tomography (CT) overwhelmingly benefits patients when used for appropriate indications, concerns have been raised regarding the potential risk of cancer induction from CT due to the exponentially increased use of CT in medicine. Keeping radiation dose as low as reasonably achievable, consistent with the diagnostic task, remains the most important strategy for decreasing this potential risk. This article summarizes the general technical strategies that are commonly used for radiation dose management in CT. Dose-management strategies for pediatric CT, cardiac CT, dual-energy CT, CT perfusion and interventional CT are specifically discussed, and future perspectives on CT dose reduction are presented.
