CT Fractional Flow Reserve: A Practical Guide to Application, Interpretation, and Problem Solving.

Radiographics, 2022
CT fractional flow reserve (FFRCT) is a physiologic simulation technique that models coronary flow from routine coronary CT angiography (CTA). To evaluate lesion-specific ischemia, FFRCT is measured 2 cm distal to a stenotic lesion.

Fractional Flow Reserve

MD Conference Express, 2012
Fractional flow reserve has become an essential tool in the modern catheterization laboratories. FFR has shown to be more accurate for the detection of ischemia than available non-invasive methods. Unlike these modalities, FFR is able to pinpoint the lesions causing ischemia, thereby achieving unequaled spatial resolution. Its use has been validated in
