心电编辑技术在64排螺旋CT冠状动脉血管成像中的应用观察

Application of ECG Editing Technique in 64-slice Spiral CT Coronary Angiography

目的 探讨心电编辑技术在64排螺旋CT冠状动脉血管成像后处理中的作用.方法 选取我院2015年6月~2016年6月行64排螺旋CT冠状动脉成像时心电信号出现异常的50例患者使用心电编辑技术前后的重建图像进行对比.结果 右冠状动脉、左主干、左前降支使用心电编辑后优和良级所占总体比均较编辑前高,编辑后的差级总体比较编辑前低,P均<0.05,有统计学意义;左回旋支对比编辑前后结果差异无统计学意义(P>0.05),不具备可比性.结论 心电编辑技术能提高64排螺旋CT冠状动脉血管成像后处理图像的质量.

Objective To explore the role of ECG editing in the post-treatment of coronary angiography with 64-slice spiral CT.Methods From June 2015 to June 2016,50 patients with ECG abnormalities under 64-slice spiral CT coronary angiography were compared before and after reconstruction using ECG.Results The right left main coronary artery,left anterior descending,using ECG editing excellent or good level for overall than were edited high,after editing the poor overall relatively low before editing,P<0.05,there was statistical significance;left circumflex artery contrast before and after editing results had no significant difference(P>0.05),not comparable.Conclusion ECG editing technique can improve the 64-slice spiral CT coronary artery imaging postprocessing image quality.
