CT Angiography (CTA)

This channel includes news and new technology innovations for CT systems use a series of X-ray images to create an image volume datasetthatcan slices 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.

Collage depicts broad applications in machine learning or deep learning (DL) that can be applied to advanced medical imaging technologies. Size of the liver and its fat fraction — 22 percent — (top middle in collage) can be quantified automatically using an algorithm developed by Dr. Albert Hsiao and his team at the University of California San Diego. This and other information that might be mined by DL algorithms from CT and MR images could help personalize patients’ treatment. Collage provided by Albert Hsiao

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.
