Prevalence of Coronary Artery Calcification in Non‐Contrast Non ECG‐Gated Chest CT Scan of Patients With Significant Stenosis in Conventional Angiography in Comparison to Patients Without Significant Stenosis: A Cross‐Sectional Study

The presence and extent of CAC on non-contrast, non-ECG-gated chest CT scans are correlated with significant coronary artery stenosis on angiography. These findings suggest that CAC assessment on routine chest CT scans can be used as a criterion for risk stratification and determining the need for angiographic evaluation to rule out significant stenosis.
