The purpose of this study was to evaluate the utility diffusion-weighted magnetic resonance imaging (MRI) with echo-planar (EPI) technique in depicting tumor cellularity and grading gliomas. Twenty consecutive patients (13 men 7 women, ranging age from 13 69 years) histologically proven gliomas were examined using a 1.5 T superconducting imager. Tumor cellularity, analyzed National Institutes Health Image 1.60 software on Macintosh computer, compared minimum apparent diffusion coefficient...
Our purpose was to evaluate the relationships between ratio of maximum relative cerebral blood volume (rCBV) (rCBV = rCBV[tumor]/rCBV[contralateral white matter]) and histologic angiographic vascularities gliomas using gradient-echo echoplanar MR imaging technique. We also evaluated usefulness rCBV maps for grading gliomas.We examined 30 patients with histologically verified gliomas. Gliomas were classified as glioblastoma, anaplastic glioma enhancement, without low-grade glioma. The each...
To assess the utility of both minimum apparent diffusion coefficients (ADCs) and ADC difference values for grading astrocytic tumors at magnetic resonance imaging.The hospital's institutional review board approved this retrospective study waived informed consent. Fifty patients (23 male patients, 27 female patients; median age, 53 years) with newly diagnosed were evaluated. Two observers blinded to clinical information independently measured ADCs by manually placing three five regions...
<h3>BACKGROUND AND PURPOSE:</h3> The usefulness of contrast-enhanced 3D T2-FLAIR MR imaging for the evaluation leptomeningeal diseases has not been systematically investigated. purpose this study was to assess value added by and MPRAGE sequences conventional postcontrast T1-weighted images in diseases. We also undertook vitro studies attempts understand consequences our patient study. <h3>MATERIALS METHODS:</h3> Twelve patients with confirmed underwent T1-weighted, MPRAGE, at 3T. Two...
<h3>Importance</h3> Among patients with hyperphosphatemia undergoing dialysis, it is unclear whether non–calcium-based phosphate binders are more effective than calcium-based for reducing cardiovascular events. <h3>Objective</h3> To determine lanthanum carbonate reduces events compared calcium in at risk of vascular calcification hemodialysis. <h3>Design, Setting, and Participants</h3> Open-label, randomized, parallel-group clinical trial blinded end point adjudication performed 2374 chronic...
<h3>BACKGROUND AND PURPOSE:</h3> Four-dimensional contrast-enhanced MR angiography (4D-CE-MRA) at 3T may replace digital subtraction (DSA) for certain diagnostic purposes in patients with intracranial dural arteriovenous fistula (DAVF). The aim of this study was to test the hypothesis that 4D-CE-MRA enables same characterization DAVFs as DSA. <h3>MATERIALS METHODS:</h3> population consisted 18 consecutive (11 women, 7 men; age range, 35–82 years; mean age, 64.8 years). They underwent and...
QUASAR is a particular application of the ASL method and facilitates user-independent quantification brain perfusion. The purpose this study was to assess intermodality agreement TBF measurements obtained with DSC MR imaging inter- intraobserver reproducibility glioma acquired by at 3T.Two observers independently measured in 24 patients histologically proved glioma. were performed on 3T scanners. placed 5 regions interest solid tumor rCBF maps derived from images 1 region contralateral...
To compare qualitatively and quantitatively the contrast of brain lesions detected with fluid-attenuated inversion-recovery (FLAIR) intermediate-weighted sequences at magnetic resonance (MR) imaging.In this prospective study, 47 patients suspected having a lesion underwent MR imaging FLAIR, intermediate-weighted, T2-weighted sequences. Qualitative assessment was performed conspicuity, detection, overall image artifact, additional clinical information. Contrast contrast-to-noise ratio (CNR)...
Efficiency of photocatalysis depends on the surface area and materials, we have prepared a porous ceramic substrate coated with nanosized-TiO2 for photocatalytic air cleaner. The was nano-sized TiO2 total board (30 × 30 1 cm) 7,432 m2, being 14,864 m2 as in cleaner consisting two boards intervened black lamps. Eighty percent 5 ppm acetaldehyde decomposed generated 8 carbon dioxide 3 hours efficiently continuously by passing through TiO2-coated (5 10 under light. Particulate dioxins (40...
We measured the angular dependence of central and off-axis detectors in a 2D ionization chamber array, MatriXX, applied correction factors (CFs) to improve accuracy composite dose verification IMRT VMAT. The MatriXX doses were with 10° step for gantry angles (θ) 0°-180°, 1° lateral 90°-110° phantom, 30 × 10 cm2 field 6 MV photons. also calculated under same conditions by Monte Carlo (MC) algorithm. CFs obtained as function θ from ratios MatriXX-measured MC-calculated doses, normalized at =...
Purpose: The purpose of this work was to assess the changes signal intensity on constructive interference in steady state (CISS) 3D Fourier transformation (3DFT) MRI after administration Gd-DTPA and evaluate efficacy contrast-enhanced CISS-3DFT depict seventh eight cranial nerves affected by vestibular schwannomas. Method: All scans were carried out a 1.5 T MR unit. First, an experimental study conducted sequence relation concentration contrast medium. Second, nine consecutive patients with...
Abstract Although neonates are commonly exposed to vaginal herpes simplex virus (HSV)‐2, neonatal is rare. Therefore, we analyzed paired infant and maternal HSV‐2 isolates from two cases of mother‐to‐infant transmission identify viral factors contributing vertical transmission. Sixteen with 27 genital in their third trimester were included. The significantly more temperature‐independent than the isolates. Sequence comparison revealed UL13 protein kinase (UL13‐PK) mutation both cases. In...
Immunoanalysis of blood cells on a microcapillary electrophoresis (νCE) chip has been studied using sheep erythrocytes (ShE) as an example. Two different buffer solutions, the phosphate-buffered saline (PBS) and gelatin veronal (GVB) were examined in regard to electrokinetic transport behavior ShE suspended these solutions inside rectangular channel engraved quartz chip. This clarified two advantages use GVB for on-chip cell electrophoresis: coatings prevent (i) nonspecific sticking wall,...
