本文件规定了临床诊断中多层螺旋CT诊断辐射剂量参考水平(diagnostic reference levels, DRL)。DRL不是个体接受CT检查辐射剂量的参考,而是在一个大样本调查后得出的整体水平上某一区域或全国范围内的辐射剂量参考水平。
本文件适用于多层螺旋CT检查的辐射安全和质量控制。本文件为一般参考文件,有条件者,应按患者年龄、体型、适应证、扫描设备等进一步细化扫描辐射剂量标准,在满足CT诊断要求的基础上将辐射剂量降至最低。本文件属于一个通用要求,针对具体部位,若有专业标准,应以专业标准为准。
注:本文件提供的CT诊断辐射剂量参考水平的数据来源于国内5家综合性医院(附录A),未纳入基层医院数据。考虑到儿童不同年龄段的辐射剂量差别较大,后续将对儿童部分按照年龄进行细分,给出儿童不同年龄段的辐射剂量参考水平。
