Abstract
Cardiac computed tomography (CT) is now widely accepted for evaluating coronary artery disease, owing to the rapidly developing technology since 64-detector row CT was first introduced over a decade ago. Coronary CTA enables us to detect not only coronary organic stenosis but also the plaque burden and composition of coronary atherosclerotic disease. Therefore, if coronary stenosis is present, the report should describe the plaque morphology as well as the stenosis severity. Herein, we describe the basic principles of coronary CTA interpretation according to the Society of Cardiovascular Computed Tomography reports.
