摘要目的:探讨低剂量扫描技术在双源CT冠状动脉血管成像中的可行性。方法:选取2023年2月—2024年8月于
菏泽市曹县中医医院接受双源CT冠状动脉血管成像检查的88例冠心病患者进行研究,采用双色小球法随机分为研究
组和对照组,各44例。患者均接受双源CT冠状动脉血管成像检查,对照组采用常规剂量CT扫描方法,研究组采用低
剂量CT扫描方法。比较两组辐射剂量、冠状动脉图像噪声比、冠状动脉图像增强CT值及冠状动脉异常检出率。结果:
研究组辐射剂量低于对照组,差异有统计学意义(P<0.001);两组右冠状动脉、左冠状动脉回旋支、左冠状动脉前降支
图像噪声比对比,差异无统计学意义(P>0.05);两组冠状动脉图像增强CT值对比,差异无统计学意义(P>0.05);两组
冠状动脉异常检出率对比,差异无统计学意义(P>0.05)。结论:低剂量扫描技术应用于双源CT冠状动脉血管成像检查
中,能够减轻对患者的辐射损伤,不会对检查结果造成较大的影响。
