Abstract
CTA based FFR, a software based application, enhances diagnostic value of coronary
computed tomography angiography (CTA) examination. However it remains unknown whether
it improves accuracy over the gold standard of invasive coronary angiography (ICA)
in predicting functionally significant coronary stenosis. The aim of our study was
to compare diagnostic accuracies of coronary CTA, CTA based FFR, and ICA, with invasive
FFR as the reference standard in patients with intermediate stenosis on CTA.
