Atherosclerosis most often develops gradually and slowly, starting from childhood and proceeding into adulthood with varying velocity and susceptibility to complications. The first structural change that can be detected in atherosclerosis is an increase in intima‐media thickness (IMT). Based on the course of atherosclerosis, the classic types of lesion are intimal thickening, fatty streaks, fibrous cap, and complicated lesion. A cardiac computed tomography (CT) scan is a procedure that utilizes multiple X-ray beams from different angles to acquire high-quality, three-dimensional (3D) images of your heart, along with your great vessels and surrounding structures. Cardiac CT uses advanced CT technology, with or without intravenous (IV) contrast to better visualize your heart structure and associated blood vessels. Multi-slice CT allows for easy visualization of coronary abnormalities and can get high-resolution, 3D images of your moving heart and great vessels. MSCT angiography is an excellent tool for detecting and evaluating these variants. Because it adequately delineates the angulations or kinking of the vessel, it aids in the decision of whether or not to undergo surgical treatment and prevents misdiagnosis.
