FFRCT
Pronunciation: F-F-R-C-T
Also written as: FFRCT — Fractional Flow Reserve Computed Tomography
Fractional flow reserve derived from coronary computed tomography angiography, providing non-invasive assessment of coronary stenosis hemodynamic significance.
Full Definition
Fractional Flow Reserve computed tomography (FFRCT) is an advanced computational technique that applies fluid dynamics modeling to standard coronary CTA datasets to calculate the hemodynamic significance of coronary stenoses. Unlike invasive FFR measurement during cardiac catheterization, FFRCT requires no additional radiation, contrast, or procedural risk. The technology uses computational fluid dynamics to simulate blood flow and pressure relationships across coronary lesions, generating color-coded maps that identify functionally significant stenoses. FFRCT values ≤0.80 are considered hemodynamically significant and may warrant revascularization consideration.
Usage
Usage note: Use subscript formatting for CT when possible; always include decimal values to two places.
