摘要
CT检查具有较高的辐射剂量,如何降低儿童CT检查的辐射剂量越来越重要,诊断参考水平(diagnostic reference level,DRL)是一个可以实现防护最优化、降低儿童CT辐射剂量的实用工具。本文通过对儿童CT检查中诊断参考水平的概念、制定方法、各国现状及问题进行简要总结,为我国儿童CT检查防护最优化提供参考。
Computed tomography(CT)examination may expose patients to a high radiation dose.The reduction of radiation dose in pediatric CT examinations is becoming increasingly important.The diagnostic reference level(DRL)is a practical tool that can achieve optimization of protection and reduce radiation dose in pediatric CT examinations.This article provides a brief summary of the concept,development methods,current situations by country,and issues related to the DRL in pediatric CT examinations,aiming to provide a references for radiation protection optimization in pediatric CT examinations in China.
