| 目的 统计血管造影受检者每次检查所受辐射剂量值及影响辐射剂量的相关因素,为分析、评估放射诊疗风险提供数据参考。方法 收集107例受检者检查时在线记录的全部辐射剂量值及其与剂量相关的技术参数值,按照检查区域头部、腹部和心脏进行分类,统计每例受检者的总透视时间、透视累积剂量面积乘积(DAP)、透视累积皮肤入射剂量(ESD),计算透视剂量率;统计每例受检者的造影曝光次数、造影曝光时间、采集帧频率,以及造影累积剂量面积乘积和造影累积皮肤入射剂量;统计每例受检者的透视加造影的总累积剂量面积乘积和总累积皮肤入射剂量。对所有数据分门别类进行相应的对比分析。结果 冠状动脉造影+介入,ESD为(22 285.5±18 682.7)μGy·m2,DAP为(2 942.1±2 557.3)mGy;头部血管造影DAP为(25 929.6±8 302.7)μGy ·m2,DAP为(1 288.8±682.3)mGy;腹部血管造影,DAP为(12 129.7±10 646.1)μGy·m2,ESD为(730.1±584.7)mGy。结论 血管造影受检者所受总累积剂量,冠状动脉造影相对最高,其次是头部血管造影,腹部血管造影相对较低。 |

| Objective To carry out further analysis and assessment of the radiation risk from DSA examinations and related factors. Methods All the online radiation dose values and associated parameters of the 107 patients examined were collected for purpose of statistical analyses according to their classification. Results The analyses of DSA examinations indicated: for coronary angiography, DAP was (22 285.5±18 682.7)μGy·m2, ESD was (2 942.1±2 557.3) mGy; for head angiography, DAP (25 929.6±8 302.7) μGy·m2, ESD (1 288.8±682.3) mGy; for abdominal angiography, DAP (12 129.7±10 646.1) μGy·m2, ESD (730.1±584.7) mGy. Conclusions Among total accumulated radiation dose, the dose arising form coronary angiography is the highest, followed by the head angiography, and the dose from abdominal angiography is the lowest. |
