BACKGROUND Smartphones are phone devices that may also be used for browsing, navigation and running smaller computer programs called applications. One may consider them as compact personal computers which are primarily to be used for making phone calls. Tablets or "tablet PCs" are fully functioning standalone computers the size of a thin LCD monitor that(More)
In this study, the effect of shear stress on the expression of genes of the human endothelin-1 system was examined. Primary cultures of human umbilical vein endothelial cells (HUVEC) were exposed to laminar shear stress of 1, 15 or 30 dyn cm-2 (i.e. 0.1, 1.5 or 3 N m-2) (venous and two different arterial levels of shear stress) in a cone-and-plate(More)
On the Internet, there are few pediatric radiology databases. The most important and complete Web site is, which provides many radiological links but does not have its own database. We present an Internet project called (also known as Kinderradiologie-Online). The open-source, case-oriented publication platform publishes(More)
Teaching files are an essential ingredient in residency education. The online program Radiology Teacher was developed to allow the creation of interactive and customized teaching files in real time. Online access makes it available anytime and anywhere, and it is free of charge, user tailored, and easy to use. No programming skills, additional plug-ins, or(More)
OBJECTIVE Mantle cell lymphoma (MCL) is an aggressive type of non-Hodgkin lymphoma with a propensity for extranodal involvement. The role of fluorodeoxyglucose (FDG)-positron emission tomography (PET) imaging in common types of lymphoma has been well-established. However, there is limited information in the literature about the utility of FDG-PET imaging in(More)
To investigate the metabolic behavior of different disease processes and pathology in epilepsy, fluorodeoxyglucose-positron emission tomography (FDG-PET) images of 280 patients with refractory epilepsy who had been surgically treated were retrospectively analyzed. The image findings were compared with the surgical pathology report. For all the pathology(More)
RATIONALE AND OBJECTIVES The aim of this study was to assess the ability of a semiautomated process to produce three-dimensional reconstructions of the ventricles and calculate ventricular volumes from magnetic resonance (MR) imaging data in children with structural brain abnormalities. MATERIALS AND METHODS Fourteen children referred for MR imaging of(More)
The rapid increase in the use of radiology and related exams and procedures has led to a concomitant increase in associated radiation risk. An application for the iPhone and iPod Touch called 'Radiation Passport' is described, which provides radiation dose estimates and associated cancer risks (non fatal and fatal) and serves as a method by which to track(More)
