CT-FFR对冠状动脉狭窄功能评价的临床价值

摘要

Fractional flow reserve derived from coronary computed tomography angiography (CT-FFR) is a noninvasive method for evaluation of coronary atherosclerotic artery disease (CAD). It integrates the advantages of coronary conputed tomography angiography (CCTA) and fractional flow reserve (FFR), and provides both anatomical and functional information of coronary artery. CT-FFR not only can assesse the degree of anatomical coronary artery stenosis, but also can determine whether presence of ischemia and the severity of ischemia. In this review we summarized the advantages and efficacy of CT-FFR and its clinical application.%CT冠状动脉血流储备分数（CT-FFR）可无创性检查冠状动脉粥样硬化性心脏病（冠心病），是一种结合了解剖与功能的检查方法。 CT-FFR是基于冠状动脉CT血管成像（CCTA）的影像数据测得的，具有CCTA和冠状动脉血流储备分数（FFR）的优势。 CT-FFR从解剖学方面评估病变的狭窄程度，同时可以从血流动力学方面测定狭窄冠状动脉是否存在缺血及缺血的严重程度。综述总结了CT-FFR的优势、诊段效能及其临床应用。
