背景资料：本研究旨在评价计算机断层扫描（CT）上冠状动脉狭窄对向心肌体积（V-sub）和心肌血流量（MBFsub）联合诊断性能，以通过有创冠状动脉造影（伊卡）和血流储备分数（FFR）评估阻塞性冠状动脉疾病（CAD）。方法：39例患者在伊卡之前接受了冠状动脉CT血管造影（CTA）和负荷动态心肌CT灌注（CTP）。阻塞性CAD被定义为严重（>= 70%）或中度（30-69%）狭窄，FFR
Background: This study aimed to evaluate the combined diagnostic performance of coronary artery stenosis-subtended myocardial volume (V-sub) and myocardial blood flow (MBFsub) on computed tomography (CT) for detecting obstructive coronary artery disease (CAD) assessed by invasive coronary angiography (ICA) and fractional flow reserve (FFR).Methods: Thirty-nine patients who underwent coronary CT angiography (CTA) and stress dynamic myocardial CT perfusion (CTP) prior to ICA were enrolled. Obstructive CAD was defined as severe (>= 70%) or moderate (30-69%) stenosis with FFR
