Coronary artery calcium on chest CT scans: from incidental finding to mandatory reporting Nature Reviews Cardiology, Published online: 18 June 2026; doi:10.1038/s41569-026-01317-4Coronary artery calcium visible on routine, low-dose, non-contrast, chest computed tomography (CT) scans provides clinically relevant information about cardiovascular risk, without additional radiation exposure or cost.
