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.

The TeraRecon time-volume analysis software shows myocardial perfusion in CT datasets. The color-coded myocardium shows areas of high and low contrast, similar to radiotracer PET and SPECT perfusion imaging.

High-Quality, Low-Dose CTA Imaging

This 3-D volume rendered computed tomography angiography (CTA) image was created with a Toshiba Aquilion One 320-slice system. The system can image the entire heart, 16 cm of anatomy, in a single, one-second acquisition.
