There are limited data regarding the influence of commissural malalignment of the aortic-pulmonary sinus on the arterial switch operation. Read more

Patient Size-Specific Analysis of Dose Indexes From CT Lung Cancer Screening

posted by dsct.com | Nov 23, 2017
dsct.com

The U.S. Centers for Medicare & Medicaid Services (CMS) recently approved the use of low-dose CT for lung cancer screening and described volumetric CT dose index (CTDIvol) requirements. These were based on the National Lung Screening Trial, which used only fixed-tube-current techniques. The aim of this study was to evaluate … Read more

High-pitch spiral CT: effect on image quality and radiation dose in pediatric chest CT

posted by Michael M. Lell, M.D. | Oct 26, 2017
Michael M. Lell, M.D.

Computed tomography (CT) is considered the method of choice in thoracic imaging for a variety of indications. Sedation is usually necessary to enable CT and to avoid deterioration of image quality because of patient movement in small children. We evaluated a new, subsecond high-pitch scan mode (HPM), which obviates the … Read more

Vertebral Compression Fractures: Third-Generation Dual-Energy CT for Detection of Bone Marrow Edema at Visual and Quantitative Analyses

posted by dsct.com | Sep 7, 2017

To assess the diagnostic performance of a third-generation dual-energy computed tomographic (CT) virtual noncalcium (VNCa) technique for detection of traumatic bone marrow edema in patients with vertebral compression fractures. Read more

Diagnostic value of transmural perfusion ratio derived from dynamic CT-based myocardial perfusion imaging for the detection of haemodynamically relevant coronary artery stenosis

posted by dsct.com | Aug 3, 2017
