摘要(Abstract)：

目的比较冠状动脉血管造影(coronary artery angiography,CAG)中对比剂两种注射方法的对比剂剂量与辐射剂量。方法入选2016年1月至2016年6月在辽宁省人民医院行经桡动脉CAG的患者200例,根据注射对比剂的方法分为自动注射系统(automated contrast injection system,ACIS)组与手动注射系统(manual contrast injection system,MCIS)组各100例。比较两组患者的基本资料、对比剂净用剂量、对比剂消耗剂量、造影体位数、累积透视时间、累积空气比释动能、累积剂量面积乘积。结果两组患者基本资料、对比剂净用剂量、累积透视时间、造影体位数比较,差异均无统计学意义(均P>0.05)。ACIS组对比剂消耗剂量[(71.60±13.05)ml比(100.00±0.00)ml,P<0.001]、累积空气比释动能[(377.42±121.42)m Gy比(418.07±141.62)m Gy,P=0.031]、累积剂量面积乘积[(2787.37±927.15)μGym2比(3102.68±1101.09)μGym2,P=0.030]均明显低于MCIS组,差异均有统计学意义。结论在经桡动脉CAG中应用ACIS较MCIS减少对比剂消耗剂量,降低辐射剂量。
