Correlation between Dual-Energy and Perfusion CT in Patients with Hepatocellular Carcinoma.

posted by Hatem Alkadhi, M.D., M.P.H., E.B.C.R. | Feb 6, 2017
Hatem Alkadhi, M.D., M.P.H., E.B.C.R.

Purpose: To develop a dual-energy contrast media-enhanced computed tomographic (CT) protocol by using time-attenuation curves from previously acquired perfusion CT data and to evaluate prospectively the relationship between iodine enhancement metrics at dual-energy CT and perfusion CT parameters in patients with hepatocellular carcinoma (HCC).

Carlo Nicola De Cecco, M.D., PhD

This article, part 4, discusses DECT for abdominal and pelvic applications and, at the end of each, will offer our consensus opinions on the current clinical utility of the application and opportunities for further research. Read more

Noise Texture Deviation: A Measure for Quantifying Artifacts in CT Images With Iterative Reconstructions.

posted by Hatem Alkadhi, M.D., M.P.H., E.B.C.R. | Jan 22, 2017
Hatem Alkadhi, M.D., M.P.H., E.B.C.R.

Objectives: The aims of this study were to introduce the measure noise texture deviation as quantitative parameter for evaluating iterative reconstruction (IR)-specific artifacts in computed tomography (CT) images and to test whether IR-specific artifacts, quantified through this measure, are reduced in advanced modeled IR (ADMIRE) as compared with sinogram-affirmed IR … Read more
