Coronary stenosis assessment: AI-based CT quantification, visual analysis of invasive angiography, and quantitative coronary angiography.

Subgroup analysis stratified by CACS categories On a per-patient level, the AUC of CCTA-based quantification methods, particularly the AUC of manual quantification by junior radiologists, for detecting obstructive stenosis at both 50% and 70% thresholds showed a decreasing trend with increasing CACS, whereas visual assessment of ICA maintained stable AUC values across CACS strata.
