Popis:	Coronary computed tomography angiography (CCTA) has been an established noninvasive method for detection of coronary artery disease (CAD). Although CCTA has had a high sensitivity and negative predictive value for CAD detection, specificity for obstructive CAD has been relatively low, partly due to coronary calcium, imaging artifacts, and other factors leading to an overestimation of stenosis severity. A relatively new noninvasive method of calculation of fractional flow reserve (FFR) using CCTA (FFRCT ) data has been developed. This noninvasive method yields similar results to invasive FFR measurement, improving specificity for noninvasively detecting lesion-specific ischemia thus helping guide revascularization.
