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).

An example of perivascular fat attenuation index (FAI) imaging inside the coronary vascular wall to show areas of inflammation. The technology was created by Oxford University and several experts in cardiac CT imaging say this might be a game changer to improving risk assessments.

Two examples of CT myocardial perfusion (CTP) imaging assessment software. Canon is on the left and GE Healthcare is on the right. Both of these technologies have been around for a few years, but there has been an increasing amount of clinical data from studies showing the accuracy of the technology compared to nuclear imaging, the current standard of care for myocardial perfusion imaging, and cardiac MRI.
