Comparison of quantitative stenosis characteristics at routine coronary computed tomography angiography with invasive fractional flow reserve for assessing lesion-specific ischemia

•Quantitative stenosis parameters can be assessed by routine coronary CT angiography.•CT-derived stenosis parameters can enhance detection of lesion-specific ischemia.•Lesion length/minimal lumen diameter4 may be superior to other proposed predictors of lesion-specific ischemia.
