In oncology, the apparent diffusion coefficient (ADC) measured by diffusion-weighted MR imaging (DWI) and standardized uptake value (SUV) from <sup>18</sup>F-FDG PET have similar clinical applications. The purpose of this study was to assess correlation between ADC SUV compare their potential in diagnosis prediction prognosis breast tumors. <b>Methods:</b> Seventy-nine female patients (age range, 19–69 y; average, 49.1 y) with 83 pathologically proven tumors were recruited. diagnoses...
Gamma rays with energies greater than 7 TeV from the Crab pulsar/nebula have been observed at large zenith angles, using Imaging Atmospheric Technique Woomera, South Australia. CANGAROO data taken in 1992, 1993 and 1995 indicate that energy spectrum extends up to least 50 TeV, without a change of index power law spectrum. The differential is \noindent $(2.01\pm 0.36)\times 10^{-13}(E/{7 TeV})^{-2.53 \pm 0.18} TeV^{-1}cm^{-2}s^{-1}$ between TeV. There no apparent cut-off. for photon above...
Abstract Purpose To examine the usefulness of diffusion‐weighted MRI (DW‐MRI) for detection both primary colorectal cancer and regional lymph node metastases, compare its performance with 2‐[fluorine‐18]‐fluoro‐2‐deoxy‐D‐glucose positron emission tomography (FDG‐PET) in same patients. Materials Methods We studied 25 patients known cancer. All underwent DW‐MRI FDG‐PET studies. The images were retrospectively assessed by visual inspection imaging findings compared histopathological on surgical...
The aim of this study was to survey the 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) cancer screening program conducted in Japan.The "FDG-PET program" included both FDG-PET and positron with computed (PET/CT) or without other combined tests that were performed for asymptomatic subjects. A total 155,456 subjects who underwent during 2006-2009 analyzed.Of subjects, positive findings suggesting possible noted 16,955 (10.9 %). number cases detected 1,912 (1.23 % screened cases,...
We have previously reported that cerebral blood flow decreased and oxygen extraction fraction volume increased in pediatric patients with moyamoya disease, whereas these values did not change significantly adult patients. In this study, we measured the cerebrovascular response to hypercapnia using 15O H2O positron emission tomography (PET) each group of These data were also compared transit time (cerebral volume/cerebral flow) by PET.The subjects consisted 20 disease (7 13 patients)....

Background and Purpose The acetazolamide effect is thought to reach a maximum at 10 20 minutes after administration. However, we sometimes encountered patients who showed transient deterioration of ischemic symptoms several We therefore considered that steal phenomenon may occur before the reaches maximum. evaluated time dependency on cerebral hemodynamics in with severe stenosis or occlusion unilateral internal carotid artery. Methods subjects consisted 13 Regional blood flow was measured...
We have measured the valence-band photoemission and inverse spectra of single-walled carbon nanotubes (SWNTs) with mean radii 0.7 $0.64\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ encapsulating ${\mathrm{C}}_{60}$ fullerenes (peas), so-called ``peapods.'' The spectrum peas in SWNTs is obtained by subtracting empty from peapod. structures pea correspond well to those a face-centered-cubic solid. No structure observed at binding energies ranging Fermi level $({E}_{\mathrm{F}})$ onset highest...
