欧洲儿童CT成像的诊断参考水平

欧盟委员会（EC）发布了最新《欧洲儿童成像诊断参考水平指南》（辐射防护第185号）。该指南详细介绍了建立欧洲儿童成像诊断参考水平（DRL）的背景、目的、方法和用法，涵盖X射线摄影、透视、CT及介入放射学（IR）方面。回顾性分析了现有欧洲儿童国家级DRL（NDRL）的现状、优势和局限性，在现有辐射剂量数据资源的基础上，达成了一些共识，出台了欧洲儿童的DRL（EDRL），为欧洲儿童的辐射防护优化提供了最新的指导意见。对于国内放射从业人员了解相关知识具有积极的借鉴意义。

Diagnostic reference levels of peadiatric CT imaging in Europe

European Commission (EC) has released the latest European guidelines on diagnostic reference levels for paediatric imaging (radiation protection No.185BF])BFQ]. The guidelines detailed the background, purpose, methods and uses of establishing the diagnostic reference levels (DRL) for European paediatric imaging, including radiography, fluoroscopy, computed tomography (CT) and interventional radiology (IRBF])BFQ]. The current situation, strengths and limitations of existing European paediatric national DRL (NDRL) were analyzed retrospectively. Based on the existing radiation dose data resources, some consensus was reached and the European DRL (EDRL) was issued, providing the latest guidance for the optimization of radiation protection of European children. It has positive reference significance for the domestic radiology practitioners to understand relevant knowledge.
