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. Find more news on cardic CT in the Society of Cariovascular Computed Tomography (SCCT) channel page.

Figure 1: A computed tomography angiography (CTA) study performed for transcatheter aortic valve replacement planning. The aortic valve is trileaflet with significant calcification (A). Annular measurements are performed to determine valve sizing (B). Coronary artery height is measured to predict the risk of coronary artery obstruction (C).

SyncVision iFR Co-registration from Philips Healthcare maps pressure readings onto angiogram. Results from an international study presented at ACC 2019 indicates pressure readings obtained using iFR (instantaneous wave-free ratio, also referred to as instant wave-free ratio or instant flow reserve) in coronary arteries may localize stenoses that remain after interventions. FFR in the cath lab.

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
