Coronary artery fractional flow reserve (FFR) derived from CT angiography (FFTCT) enables functional assessment of coronary stenosis. Prior clinical trials showed 13%-33% of coronary CT angiography studies had insufficient quality for quantitative analysis with FFRCT. To determine the rejection rate of FFRCT analysis and to determine factors associated with technically unsuccessful calculation of FFRCT.
