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

Low contrast medium-volume third-generation dual-source CT angiography for transcatheter aortic valve replacement planning.

posted by Carlo Nicola De Cecco, M.D., PhD | Mar 12, 2017
Carlo Nicola De Cecco, M.D., PhD

Purpose: To investigate feasibility, image quality and safety of low-tube-voltage, low-contrast-volume comprehensive cardiac and aortoiliac CT angiography (CTA) for planning transcatheter aortic valve replacement (TAVR). Read more

Correction Factors for CT Coronary Artery Calcium Scoring Using Advanced Modeled Iterative Reconstruction Instead of Filtered Back Projection.

posted by Carlo Nicola De Cecco, M.D., PhD | Mar 2, 2017
Carlo Nicola De Cecco, M.D., PhD

Rationale and Objectives: Iterative reconstruction (IR) computed tomography (CT) techniques allow for radiation dose reduction while maintaining image quality. However, CT coronary artery calcium (CAC) scores may be influenced by certain IR algorithms. The aim of our study is to identify suitable correction factors to ensure consistency between IR and … Read more

Diagnostic accuracy of coronary CT angiography using 3rd-generation dual-source CT and automated tube voltage selection: Clinical application in a non-obese and obese patient population.

posted by Carlo Nicola De Cecco, M.D., PhD | Feb 21, 2017
Carlo Nicola De Cecco, M.D., PhD

Purpose: To investigate diagnostic accuracy of 3rd-generation dual-source CT (DSCT) coronary angiography in obese and non-obese patients. Read more

Optimization of window settings for standard and advanced virtual monoenergetic imaging in abdominal dual-energy CT angiography.

posted by Carlo Nicola De Cecco, M.D., PhD | Feb 16, 2017
Carlo Nicola De Cecco, M.D., PhD

Objectives: To determine the optimal window setting for displaying virtual monoenergetic reconstructions of third generation dual-source, dual-energy CT (DECT) angiography of the abdomen. Read more
