Image Reconstruction,nt to the radiologist, as the huge amount of digital information acquired is used to reconstruct three-dimensional images of the coronary arteries, according to dedicated and complex software and protocols. The coronary arteries are tortuous, moving objects and are thus often not easily visualized.

Coronary Pathophysiology,an any other organ, cycling about 6 kg of ATP, which is 20–30 times its own weight, every day. To acquire this enormous amount of energy, the heart converts chemical energy stored in fatty acids and glucose into mechanical energy, in the form of actinomyosin myofibrillar interactions. Fatty acids, t

Identification and Characterization of the Atherosclerotic Plaque Using Coronary CT Angiography,ting arteries. Catheter coronary angiography, by contrast, only evaluates the internal, patent lumen of these vessels, without providing direct information on the vessel wall or the extent of vascular parietal involvement by atherosclerosis. While it identifies areas of stenosis or obstruction, it d

Coronary CT Angiography: Evaluation of Stenosis and Occlusion,e extent of atherosclerotic involvement, i.e., significant reduction of the lumen by stenosis or complete occlusion of the vessel. A reduction in the caliber of the vessel lumen is associated with a reduction in blood flow and may have significant hemodynamic consequences; however, an important and
