Why the study?
CAD accounts for over 16% of deaths worldwide, and a noninvasive modality to triage and stratify disease severity would be clinically useful.

Supports ruling in stenosis on fluoroscopy; leaves open screening utility in cross-sectional data.
Does fluoroscopically detected coronary artery calcification accurately predict significant coronary stenosis compared to coronary angiography?
Fluoroscopic detection of coronary artery calcification has high specificity and positive predictive value for significant coronary stenosis, but its low sensitivity limits its utility as a standalone screening tool.
