Nonlinear and Vessel-Specific Association Between Coronary Artery Calcium Burden and Coronary Computed Tomography Angiography Underestimation of Coronary Stenosis
Background: Coronary artery calcium (CAC) introduces substantial artifacts in coronary computed tomography angiography (CCTA). Although calcification is classically associated with overestimation of stenosis severity, underestimation may be even more clinically hazardous because underestimation can lead to inappropriat...
