The use of computed tomography (CT) has increased dramatically over the past several decades and has resulted in a concurrent increase in medical exposure to ionizing radiation. Several recent studies have examined the link between medical radiation and the risk of cancer, especially in children. The cancer risk associated medical exposure has not been definitively confirmed. However, we have to reduce unwarranted medical radiation exposure in pediatric patients. Justification and optimization are of great importance in order to minimize these risks, and the standardization of CT usage is essential. However, in Japan no clinical guidelines for the use of CT have been commonly agreed upon, especially in children. Furthermore, the CT-associated radiation exposure in Japan varies widely among the different facilities. Further studies based on a nationwide survey in Japan will be required in order to establish simple and useful clinical guidelines.
在过去几十年中，计算机断层扫描（CT）的使用急剧增加，导致医疗中电离辐射暴露同时增加。最近的几项研究探讨了医疗辐射与癌症风险之间的联系，尤其是在儿童中。与医疗暴露相关的癌症风险尚未得到明确证实。然而，我们必须减少儿科患者不必要的医疗辐射暴露。为了将这些风险降至最低，正当性和优化非常重要，CT使用的标准化至关重要。然而，在日本，尚未就CT的使用达成普遍认可的临床指南，尤其是在儿童中。此外，日本不同医疗机构之间CT相关的辐射暴露差异很大。为了制定简单实用的临床指南，需要在日本进行全国范围的进一步研究。
