Abstract
European Commission (EC) has released the latest European guidelines on diagnostic reference levels for paediatric imaging (radiation protection No.185). 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 (IR). 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.
