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

Prospective Randomized Comparison of High-pitch CT at 80 kVp Under Free Breathing with Standard-pitch CT at 100 kVp Under Breath-Hold for Detection of Pulmonary Embolism.

Hatem Alkadhi, M.D., M.P.H., E.B.C.R.

Rationale and Objectives: To prospectively compare high-pitch computed tomography (HPCT) under free breathing (FB) with standard-pitch CT (SPCT) under breath-hold (BH) for detection of pulmonary embolism (PE). Read more

Effect of Localizer Radiography Projection on Organ Dose at Chest CT with Automatic Tube Current Modulation.

posted by Hatem Alkadhi, M.D., M.P.H., E.B.C.R. | Jan 12, 2017
Hatem Alkadhi, M.D., M.P.H., E.B.C.R.

Purpose: To calculate the effect of localizer radiography projections to the total radiation dose, including both the dose from localizer radiography and that from subsequent chest computed tomography (CT) with tube current modulation (TCM). Read more

Third-generation dual-source 70-kVp chest CT angiography with advanced iterative reconstruction in young children: image quality and radiation dose reduction platform.

posted by Michael M. Lell, M.D. | Oct 25, 2016
Michael M. Lell, M.D.

Objective: To evaluate image quality and radiation dose of high-pitch second- and third-generation dual-source chest CT angiography and to assess the effects of different levels of advanced modeled iterative reconstruction (ADMIRE) in newborns and children. Read more
