CT Angiography (CTA)

This channel includes news and new technology innovations for CT systems using a series of X-ray images to create an image volume data set that can be sliced or 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 souce CT), and interative reconstruction dose reduction software.

An example of a HeartFlow FFR-CT image showing the blood flow through what looked like a significant blockage on CT angiography alone, actually was not flow-limiting based on computational fluid dynamics. Use of the technology was supposed to reduce the number of diagnostic catheterizations in the FORECAST trial, but the costs of FFR-CT were not offset enough to show cost savings.

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).

Figure 4 for the study. Images of a 65-year-old man (patient 6). (a) Cardiac MRI perfusion shows perfusion deficit of anterior/anterolateral wall attributed to left anterior descending artery/left circumflex artery (*). (b) CT coronary angiography. (c) Coronary angiography, left anterior oblique projection with caudal angulation. (d) Three-dimensional image fusion helped refine diagnosis: perfusion deficits (*) were most likely caused by narrow first diagonal branch and its first, stented side branch.
