Highlight
Nongated chest CT scans for coronary artery calcium (CAC) scoring strongly correlate with standard gated scans (r=0.961), enabling accurate cardiovascular risk prediction.
Moderate and severe CAC detected on nongated scans are associated with significantly increased risk of coronary heart disease and cardiovascular events.
Prognostic performance metrics (AUC, C-statistic, Brier score) for nongated CAC measures are comparable to gated CAC, supporting clinical utility.
Incorporation of incidental CAC quantification from nongated scans aligns with upcoming 2026 ACC/AHA dyslipidemia guidelines, enhancing personalized preventive strategies.
