基于CCTA的血流储备分数临床应用进展

Progress in the Clinical Application of Fractional Flow Reserve Based on Coronary CT Angiography

摘要: 近年来基于冠状动脉CT血管成像衍生的无创血流储备分数（FFR<sub<CT</sub<）是心血管成像的一项重大进步，血流储备分数能够识别病变特异性缺血，并为血运重建的临床决策提供信息，充当有创性冠状动脉造影（ICA）的把关人。本文旨在综述FFR<sub<CT</sub<的研究进展，并简要探讨存在的局限性。

Abstract: Noninvasive coronary fractional flow reserve derived from CT angiography (FFR<sub<CT</sub<) is a major advance within cardiovascular imaging in recent years. It can identify pathology-specific ischemia and provide information for clinical decisions on revascularization, serving as a gatekeeper for invasive coronary angiography.This paper reviews the research progress of FFR<sub<CT</sub< and briefly discusses its limitations.
