心电编辑在64层螺旋CT冠状动脉成像中的价值

Clinical Value of ECG-editing in 64-Slice Spiral CT Coronary Angiography

目的探讨心电编辑在64层螺旋CT冠状动脉成像(CTA)中的价值。方法应用心电编辑功能,对23例CTA检查过程中出现心律失常者的图像进行重建,比较心电编辑前后图像质量。结果心电编辑前图像评分1-4级者分别有82、93、36、19节段;心电编辑后图像1-4级分别分别有111、80、25、14节段。心电编辑后图像质量显著改善(Z=6.787,P=0.000 1)。结论心电编辑可改善多数心律失常患者CT冠状动脉成像的图像质量。

Objective To explore the value of ECG-editing in 64-slice CT coronary angiography.Methods ECG editing was performed in reconstruction of images of 23 patients with arrhythmia detected with 64-slice CT coronary angiography（CTA）,and the images of CTA before and after ECG editing were compared.Results Grade 1-4 of the image quality were 82,93,36,19 sections before ECG-editing,respectively.Grade 1-4 of the image quality were 111,80,25,14 sections after ECG-editing,respectively.The image quality were significantly improved after ECG-editing（Z=6.787,P=0.000 1）.Conclusion ECG-editing can significantly improve the image quality of 64-slice CT coronary angiography.
