Advanced coronary atherosclerosis is characterized by calcium deposition. Although coronary calcium had been visualized by fluoroscopy and conventional computed tomography (CT), it was not until the introduction of electron beam computed tomography (EBCT) that high-resolution, motion-free images of the coronary arteries could be acquired. In their seminal paper from 1990, Agatston et al. 1 describe a methodology to image and quantify calcium in...
