目的 确定 320 排多排冠状动脉计算机断层扫描血管造影 (M320-CCTA) 以血流储备分数 (FFR) 作为参考标准检测功能性狭窄并预测稳定型冠状动脉疾病血运重建的准确性。 方法 对 115 名患者（230 条血管）进行 M320-CCTA 和 FFR 评估，并随访 18 个月。侵入性血管造影 (ICA) 和 M320-CCTA 的直径狭窄由两名观察者一致评估，显着狭窄定义为 >= 50%。 FFR
Objectives To determine the accuracy of 320-row multidetector coronary computed tomography angiography (M320-CCTA) to detect functional stenoses using fractional flow reserve (FFR) as the reference standard and to predict revascularisation in stable coronary artery disease.Methods One hundred and fifteen patients (230 vessels) underwent M320-CCTA and FFR assessment and were followed for 18 months. Diameter stenosis on invasive angiography (ICA) and M320-CCTA were assessed by consensus by two observers and significant stenosis was defined as >= 50 %. FFR
