Computed Tomography (CT)

Computed tomography (CT) systems use a series of X-ray images to create an image volume dataset with slices that can be 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-source CT), and iterative reconstruction dose reduction software.

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.
