BACKGROUND/PURPOSE: Over the past several years, increasing attention has been focused on the potential for radiation exposure from computed tomography (CT) for inducing the development of cancers. An understanding of these issues is important for the practice of pediatric surgery.
Medline based clinical review of current medical literature of the risks for the induction of cancers by CT. Data includes estimates of cancer risk from computer models, epidemiologic data from survivors of atomic bomb radiation exposure, and consensus opinions from expert panels.
Review of scientific evidence demonstrates varied opinions, but consensus suggests there may be a potential for an increased risk of cancer from low level radiation exposure such as from CT. These calculations suggest that there may be as high as 1 fatal cancer for every 1000 CT scans performed in a young child.
Pediatric surgeons should be aware of the potential risks of CT. Minimizing the radiation risks of CT is a complex endeavor, and will require investments from pediatric surgeons as well as pediatric radiologists.
背景/目的：在过去几年中，计算机断层扫描（CT）辐射致癌的可能性受到了越来越多的关注。了解这些问题对于小儿外科手术的实践很重要。
基于医学文献数据库（Medline）对CT致癌风险的当前医学文献进行临床综述。数据包括计算机模型对癌症风险的估计、原子弹辐射暴露幸存者的流行病学数据以及专家小组的共识意见。
对科学证据的综述表明存在不同观点，但共识认为低剂量辐射暴露（如CT辐射）可能会增加患癌风险。这些计算表明，在幼儿中每进行1000次CT扫描可能会导致多达1例致命癌症。
小儿外科医生应意识到CT的潜在风险。将CT的辐射风险降至最低是一项复杂的工作，需要小儿外科医生和小儿放射科医生的投入。
