Abstract:
Coronary computed tomography angiography (CTA) has become an important part of current cardiovascular care and is the first-choice imaging modality for noninvasive visualization of coronary artery plaque and stenosis. It has high sensitivity for the detection of coronary stenosis and excellent negative predictive value to rule out stenosis with consistently high image quality at low radiation doses. In this article, we point out the technical aspects of modern coronary CT imaging, give a comprehensive overview of coronary CTA interpretation, including standardized reporting, and point out body of evidence for current clinical use.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
