FFRCT
Pronunciation: eff-eff-are-see-tee
Also written as: FFRCT — Fractional Flow Reserve derived from Coronary CT Angiography
Non-invasive computational technique for determining coronary lesion hemodynamic significance from CT angiography.
Full Definition
Fractional Flow Reserve derived from Coronary CT Angiography represents a revolutionary non-invasive technique that applies computational fluid dynamics to standard coronary CT angiography datasets to determine the hemodynamic significance of coronary stenoses. FFRCT eliminates the need for invasive pressure wire assessment while providing lesion-specific functional information similar to invasive FFR. The technique requires high-quality CT angiography with specific acquisition protocols and off-site computational analysis. FFRCT values ≤0.80 indicate hemodynamically significant stenosis, matching the threshold established for invasive FFR. This technology enables comprehensive anatomical and functional coronary assessment in a single non-invasive study.
Usage
Usage note: Always specify the computational method and reference normal FFR thresholds.
