Computed Tomography (CT)

Cardiac computed tomography CT systems use a series of X-ray images to create an image volume dataset that can be sliced or manipulated on any plane using advanced visualization software. This channel includes content on CT scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (also called dual souce or dual energy CT), and interative image reconstruction software that can reduce dose and make lower-quality CT images diagnostic.

Abdominal Aortic Calcification May Signal Future Heart Attack

Image from computed tomography (CT) colonography shows segmented abdominal aortic calcification measured with semiautomated CT tool on coronal image. Within region of interest over aorta selected by user, tool automatically segments and quantifies aortic calcification (shown in blue).

CT-FFR example showing heavily calcified coronary arteries on CT that did not have hemodynamically significant impact on blood flow.

FFR-CT was by far the hottest cardiac technology topic on DAIC in July. Eight of the top 20 pieces of content were about or mention FFR-CT. This image shows an example of the image-based technology that noninvasively assesses coronary fractional flow reserve (FFR) for the entire coronary tree. The CT image on the left shows two heavily calcified coronary arteries, but the FFR-CT analysis shows there is not a significant impact on hemodynamics, so the patient does not need revascularization.
