本回顾性研究旨在比较320排计算机断层扫描（CT）和第二代（128层）双源CT在前瞻性ECG门控方法上的右冠状动脉（RCA）图像质量和有效辐射剂量。共215名候选人采用前瞻性心电门控方法进行了CT冠状动脉造影，320排CT组120例，双源CT组95例。我们将RCA图像质量评分分为1/2/3/4，这意味着极好/良好/足够/不可评估，并考虑了心率以及辐射剂量。320排CT与第二代双源CT的RCA图像质量评分1/2无统计学差异，但心率较低（
This retrospective study was to compare the image quality of right coronary artery (RCA) and effective radiation dose on prospective ECG-gated method between 320 row computed tomography (CT) and 2nd generation (128-slice) dual source CT. A total of 215 candidates underwent CT coronary angiography using prospective ECG-gated method, 120 patients enrolled in 320 row CT group, and 95 patients in dual source CT group. We divided RCA image quality scores as 1/2/3/4, which means excellent/good/adequate/not assessable and heart rates were considered, as well as the radiation dose. There is no statistically significant difference of RCA image quality of Score 1/2 between 320 row CT and 2nd generation dual source CT, but lower heart rate (
