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.

$Cardiac CTA derived left atrium emptying fraction (LAEF) improves predictive performance of established clinical risk scores and may be used to assess TAVR patient risk during pre-procedure workup and post-procedural surveillance. These images show LAVmax (A and B), LAVmin (C and D), and LAEF using cardiac CTA. LAEF was calculated as (LAVmax-LAVmin)/LAVmax x 100. Given LAVmax of 109 mL and LAVmin of 80 mL, the LAEF was calculated to be 27%. Image courtesy of AJR.$
