To develop a second set of diagnostic reference levels (DRLs) and achievable doses (ADs) for 13 adult computed tomography (CT) protocols and a paediatric head CT protocol in Korea. A survey of 13,625 CT examinations was performed based on 13 adult CT protocols and a paediatric non-contrast brain CT protocol using 369 CT systems, with patients grouped according to age. Most CT protocols in this survey had DRLs similar to those reported in other countries. However, chest and abdomen-pelvic CT had lower DRLs than those reported in the first Korean national survey and those from other countries. Paediatric non-contrast brain CT in each age group, with the exception of the 11-15-year age group, had lower DRLs than those reported in other countries. The DRLs presented here are similar to (or lower than for some protocols) those reported in the first Korean national survey and those from other countries.
为韩国的13种成人计算机断层扫描（CT）方案和1种儿科头部CT方案制定第二套诊断参考水平（DRLs）和可实现剂量（ADs）。基于13种成人CT方案和1种儿科非增强脑CT方案，使用369台CT系统对13625例CT检查进行了调查，患者按年龄分组。本次调查中的大多数CT方案的诊断参考水平与其他国家报告的相似。然而，胸部和腹部-盆腔CT的诊断参考水平低于韩国首次全国调查以及其他国家报告的水平。除11 - 15岁年龄组外，各年龄组的儿科非增强脑CT的诊断参考水平低于其他国家报告的水平。此处呈现的诊断参考水平与韩国首次全国调查以及其他国家报告的水平相似（或某些方案更低）。
