摘要:
目的对比采用国际放射防护委员会（ICRP）６０和ICRP１０３组织器官权重因子计算冠状动脉血管造影术（CAG）及经皮穿刺腔内冠状动脉成形术（PCI ）所致有效幅射剂量的变化。方法采用在ART仿真人体辐照体模（fluke biomedical）躯干部分布放热释光剂量计的方法获得器官剂量，再将器官剂量按照不同版本ICRP组织器官权重因子加权求和获得有效剂量。分析有效剂量变化趋势及原因。同时计算有效剂量与剂量面积乘积（DAP）转换系数。结果ICRP１０３对组织器官权重因子进行调整后带来了有效剂量的增加：CAG（６．８８％）和PCI （８．４６％）。对于CAG、PCI 诊疗过程，权重因子的变化带来女性有效剂量的变化为７．２５％（８．７６％），男性有效剂量的变化为６．５１％（８．１７％）；有效剂量对DAP的转换系数也从０．１０（０．１３）变为０．１１（０．１４）。结论ICRP１０３对组织器官权重因子的调整导致了CAG和PCI 诊疗过程所致患者器官剂量的增加，对于有效剂量增加幅度PCI 略高于CAG，女性患者略高于男性患者。有效剂量的增加有两方面原因：器官权重因子变化小而器官当量剂量大和器官当量计量小但器官权重因子变化大。有效剂量和DAP之间转换系数的变化表明在介入放射工作中用转换系数估算患者有效剂量时要考虑新版本ICRP对组织器官权重因子的调整。
