摘要
冠状动脉CTA作为一项微创检查,一直以来临床应用范围较局限,主要受限于螺旋CT时间分辨率较低[1]。自从双源螺旋CT应用于临床以来,冠状动脉CTA检查不再依赖于药物控制心率,检查成功率也明显提高。双源螺旋CT时间分辨率明显提高。
Objective To investigate the value of ECG editing in dual-source CT coronary angiography in patients with atrial fibrillation（Af）. Methods 38 patients with Af underwent dual-source CT coronary angiography. The ECG editing technique was applied to get the processing and reconstruction of image. The coronary imaging before and after ECG-editing was evaluated with four-score method and the significant difference was compared. Results In 38 patients of Af, a total of 494 coronary artery segments were evaluated after ECG-editing. Among of them, 179（36.22% ） segments were evaluated score 4, 161 （32.63 % ） segments were evaluated score 3, 107（21.71% ） segments were evaluated score 2 and 47（ 10% ） segments were evaluated score 1. The average score of before ECG-editing was（2.49± 0.57）, and the average score of after ECG-editing group was（3.34± 0.47）. The difference between two groups was significant（ P 〈 0.01）. Conclusions ECG editing technique can effectively improve the image quality of dual-source CT coronary angiography in patients with Af.
