Abstract

Coronary computed tomography (CT) angiography plays a pivotal role in the diagnosis and treatment of patients with artery disease. However, unlike conventional CT systems,  photon-counting computed tomography (PCCT) introduces substantial technological improvements, includes improved spatial and contrast resolution, energy discrimination, and reduction of various artifacts. As a result, PCCT enables superior coronary lumen and plaque evaluation, even in complex cases with severe calcification or smaller coronary stents. Beyond the coronary arteries, PCCT offers improved visualization of cardiac anatomy and myocardial tissue characterization with the potential to reduce downstream testing, improve diagnosis and treatment, and ultimately improve clinical outcomes. This review explores the technical principles of PCCT, its advantages over conventional CT, and its current and potential future applications in cardiac imaging.
