Axial noncontrast CT scans in participants with/without coronary artery calcium.

Caption

Example axial noncontrast CT scans in (A, C, E) a participant with a coronary artery calcium (CAC) score of 0, no signs of coronary artery disease at CT, and no major adverse cardiovascular events and (B, D, F) a participant who had a CAC score of 1013 (group with a CAC score of 400 or higher) and obstructive coronary artery disease at CT and required a revascularization procedure. With the scan on the left as reference, calcified plaques (ovals) can be seen on the right scan of the left main and left anterior descending arteries (proximal and mid segment, B) and the right coronary artery (proximal vessel segment, D; middle vessel segment, F).
