Computed Tomography (CT)

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. The section includes content on computed tomography scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (dual souce CT), and interative reconstruction dose reduction software.

Coronary CT angiography images of a coronary artery depicting the perivascular fat attenuation index (FAI) before and after biologic therapy at one-year follow-up. Patients had excellent response to biologic therapy, showing clear reductions in the inflammation in plaques that cause heart attacks and stokes.

An example of FFR-CT imaging from Beaumont Hospital in Royal Oak, Mich. The left image shows a 3D generated image of the coronary tree from a CT scan evaluated with computational fluid dynamics to determine the FFR numbers. It shows a severe restriction of the left main artery which requires a stent to revacularize. The image on the right is a comparison with the invasive angiogram from the cath lab prior to stenting.
