OBJECTIVE To describe the determinants of the severity of the head kinematics of a pedestrian when struck by common sport utility vehicles (SUV) and work utility vehicles (WUVs) to assess how effective assessment protocols are in assessing injury risk for SUVs and work utilities. METHODS Three hundred twenty-four simulations of pedestrian collisions with SUVs, work utility vehicles, and sedan...

It has been shown that the intratumor heterogeneity can be characterized with quantitative analysis of the [18]F-FDG PET image data. The existing models employ multiple parameters for feature extraction which makes it difficult to implement in clinical settings for the quantitative characterization. This article reports an easy-to-use and differential SUV based model for quantitative assessment...

One of the early promises of PET was that it would be quantitative (1), as opposed to imaging modalities such as x-ray CT, MRI, or SPECT, in which quantification is more of a challenge than in PET. By quantitative is meant that a raw PET signal can be transferred into absolute activity concentrations of the radiopharmaceutical in all tissues in units of, for example, kBq/cm3. In this sense, PET...

Drivers have been running an “arms race” on American roads by buying inc reasingly large vehicles such as SUVs and light trucks. An important reason for the popularity of large vehicles is that families view them as providing better protection to their occupants if a crash occurs. But when families drive large vehicles, they pose an increased danger to occupants of smaller vehicles and to pedes...

Acknowledgments The authors are indebted to P. Briole and G. Nunnari for their enthusiasm towards experimenting with GPS methodology on Mt. Etna since 1988 and for their work on making it a powerful tool for research and monitoring in volcanology. Sincere thanks are also due to Prof L. Villari for having started the ground deformation study on Sicilian volcanoes in the 1970s and for helping car...

PURPOSE A new image-based methodology is developed for estimating the apparent space-filling properties of an object of interest in PET imaging without need for a robust segmentation step and used to recover accurate estimates of total lesion activity (TLA). METHODS A multifractal approach and the fractal dimension are proposed to recover the apparent space-filling index of a lesion (tumor vo...

The testis shows physiologic uptake in flourine-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography (PET). The purpose of this study was to examine the degree of FDG uptake of normal testis on PET/computed tomography (CT), especially in relationship to various clinical parameters. We obtained the maximum standardized uptake value (SUVmax) and the mean standardized uptake value (SUVmea...

The aim of this study is to assess the performance of 18F-FDG whole body PET/MRI in comparison with PET/CT based on SUV. Anatomical location of lesion with Dixon MRI and additional value of advanced MRI technology such as diffusion weighted MR imaging in diagnosis of malignant disease will also be investigated. which permits unrestricted use, distribution, and reproduction in any medium, provid...

UNLABELLED The aim of this study was to determine the normal l-[methyl-(11)C]-methionine ((11)C-methionine) uptake and the extent of variation using standardized uptake value (SUV). METHODS Five healthy volunteers and 58 adult patients with normal (11)C-methionine uptake were included in the interindividual analysis and 22 patients in the intraindividual analysis. SUVs in different brain regi...
