Influence of technical parameters on epicardial fat volume quantification at cardiac CT

posted by Carlo Nicola De Cecco, M.D. | Aug 24, 2015
Carlo Nicola De Cecco, M.D.

Measured EATV can differ substantially between contrast enhanced and non-contrast CT studies, which can be reconciled by threshold modification. Heart cycle phase does not significantly influence EATV measurements. Read more

CT Evaluation of Small-Diameter Coronary Artery Stents: Effect of an Integrated Circuit Detector with Iterative Reconstruction

posted by U. Joseph Schoepf, M.D. | Aug 4, 2015
U. Joseph Schoepf, M.D.

The implementation of an integrated-circuit CT detector provides substantially sharper out-of-plane resolution of coronary artery stents at 0.5-mm section thickness, while the use of iterative image reconstruction mostly improves in-plane stent visualization. Read more

Automated tube voltage selection in thoracoabdominal CT at high pitch using a third-generation dual-source scanner: image quality and radiation dose performance

posted by Michael M. Lell, M.D. | Jul 29, 2015
Michael M. Lell, M.D.

Automated tube voltage adaptation combined with high-pitch protocols allows for a substantial radiation dose reduction while substantially increasing the image quality, even at large-volume exposure. Read more
