In August 2017, the European Commission awarded the "European Study on Clinical Diagnostic Reference levels for X-ray Medical Imaging" project to the European Society of Radiology, to provide up-to-date Diagnostic Reference Levels based on clinical indications. The aim of this work was to conduct an extensive literature review by analysing the most recent studies published and the data provided by the National Competent Authorities, to understand the current situation regarding Diagnostic Reference Levels based on clinical indications for computed tomography.
The literature review has identified 23 papers with Diagnostic Reference Levels based on clinical indications for computed tomography from 15 countries; 12 of them from Europe. A total of 28 clinical indications for 6 anatomical areas (head, cervical spine/neck, chest, abdomen, abdomen-pelvis, chest-abdomen-pelvis) have been identified.
In all the six anatomical areas for which Diagnostic Reference Levels based on clinical indications were found, a huge variation of computed tomography dose descriptor values was identified, providing evidence for a need to develop strategies to standardise and optimise computed tomography protocols.
2017年8月，欧盟委员会将“X射线医学成像临床诊断参考水平的欧洲研究”项目授予欧洲放射学会，以根据临床指征提供最新的诊断参考水平。这项工作的目的是通过分析已发表的最新研究以及国家主管当局提供的数据进行广泛的文献综述，以了解基于计算机断层扫描临床指征的诊断参考水平的现状。
文献综述确定了来自15个国家的23篇关于基于计算机断层扫描临床指征的诊断参考水平的论文；其中12篇来自欧洲。已确定了6个解剖区域（头部、颈椎/颈部、胸部、腹部、腹部-骨盆、胸部-腹部-骨盆）的总共28种临床指征。
在所有发现基于临床指征的诊断参考水平的六个解剖区域中，均发现计算机断层扫描剂量描述符值存在巨大差异，这为制定标准化和优化计算机断层扫描方案的策略提供了证据。
