Computed Tomography (CT)

Computed tomography (CT) systems use a series of X-ray images to create an image volume dataset with slices that can be manipulated on any plane using advanced visualization software. The section includes computed tomography scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (dual-source CT), and iterative reconstruction dose reduction software.

Sheer stresses on the walls of arteries are believed to cause the formation atherosclerotic plaques. This is an area of research that is expected to see increased use in the next few years. This study was presented at SCCT 2020 as an example of how sheer stresses can help evaluate and predict the patency of coronary artery bypass grafts (CABG).
