Diagnostic Accuracy of Fractional Flow Reserve From Anatomic CT Angiography.

The article presents a study to assess the diagnostic performance of fractional flow reserve (FFR) and computed tomography (CT) for diagnosis of coronary stenosis. It informs that the coronary computed tomographic (CT) angiography is a noninvasive anatomic test for diagnosis of coronary artery disease (CAD) or stenosis irrespective of ischemia. It further adds that the fractional flow reserve (FFR) is a physiologic measure of coronary stenosis reflecting the amount of coronary flow stenosis and an invasive procedure. It is concluded that the use of noninvasive FFR and CT among stable patients of CAD are associated with improved diagnostic accuracy.
