Progress in the Application of Coronary Artery CT Angiography Blood Flow Reserve Fraction in Coronary Artery Disease
Coronary flow reserve(FFR)is the gold standard for evaluating the physiologic function of the coronary vasculature.Noninvasive flow reserve fraction(CT-FFR)based on coronary CT angiography is a new technique for the study of coronary artery disease,which applies computational fluid dynamics to anatomical data providing clinicians with further functional assessment to guide therapeutic decisions.The potential of CT-FFR is now recognized.In this review,the basic principles of CT-FFR,the diagnostic efficacy of CT-FFR for coronary artery disease and the factors affecting it,limitations and shortcomings,and future directions are presented.
