Coronary Computed Tomography: A Brief History
1Hospital of University of Pennsylvania, 3400 Spruce Street, Philadelphia, PA 19104, USA.
Abstract:
Coronary computed tomography (CT) is one of the most rigorously tested imaging modalities. The history of evidence of coronary CT reflects the hierarchical model of efficacy of diagnostic imaging proposed by Fryback and Thornbury. Coronary CT has gone through technological evolution from electron beam CT to helical CT to multidetector CT. As technology improved, it also had to meet higher bars for evidence from proof of concept to diagnostic accuracy to evidence that it improves outcomes compared with its competitors.

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 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...
