Summary of the methods of restraining the decline of evaluation accuracy on the degree of coronary stenosis caused by coronary artery calcification at the present stage

Coronary computed tomography angiography (CCTA), as a non-invasive method to detect the degree of coronary artery stenosis, is often used as a primary screening method for asymptomatic patients, but the performance in positive predictive value often fluctuates. The main reason is the partial volume effect caused by large area coronary artery calcification plaque, which limits the clinical application of CCTA. This article summarizes the methods of suppressing evaluation errors on the degree of stenosis caused by coronary artery calcification, in order to provide some reference for clinical workers in the treatment of patients with severe calcification.
