Carlo Nicola De Cecco, M.D., PhD

Purpose: To assess image quality and accuracy of CT angiography (CTA) for transcatheter aortic valve replacement (TAVR) planning performed with 3rd generation dual-source CT (DSCT). Read more

Computer-aided detection (CAD) of solid pulmonary nodules in chest x-ray equivalent ultralow dose chest CT – first in-vivo results at doselevels of 0.13 mSv

posted by Hatem Alkadhi, M.D., M.P.H., E.B.C.R. | Apr 10, 2017
Hatem Alkadhi, M.D., M.P.H., E.B.C.R.

Objectives: To determine the value of computer-aided detection (CAD) for solid pulmonary nodules in ultralow radiation dose single-energy computed tomography (CT) of the chest using third-generation dual-source CT at 100kV and fixed tube current at 70 mAs with tin filtration. Read more

Organ Dose and Attributable Cancer Risk in Lung Cancer Screening with Low-Dose CT.

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

Purpose: Lung cancer screening with CT has been recently recommended for decreasing lung cancer mortality. The radiation dose of CT, however, must be kept as low as reasonably achievable for reducing potential stochastic risks from ionizing radiation. The purpose of this study was to calculate individual patients’ lung doses and … Read more
