High b-value diffusion tensor imaging of the neonatal brain at 3T.
BACKGROUND AND PURPOSE Diffusion-weighted MR imaging studies of the adult brain have shown that contrast between lesions and normal tissue is increased at high b-values. We designed a prospective study to test the hypothesis that diffusion tensor imaging (DTI) obtained at high b-values increases image contrast and lesion conspicuity in the neonatal brain. MATERIALS AND METHODS We studied 17 n...
متن کاملDiffusion tensor MR imaging of high-grade cerebral gliomas.
BACKGROUND AND PURPOSE Optimizing high-grade glioma treatment requires the delineation of edematous and normal brain from tumor, perhaps by using potential differences in the absolute diffusion parameters of water. Our purpose was to determine whether mean diffusivity and diffusion anisotropic MR imaging data help in this differentiation. METHODS Nine patients with high-grade cerebral gli...
متن کاملSignal Intensity of High B-value Diffusion-weighted Imaging for the Detection of Prostate Cancer
Background: Diffusion-weighted imaging (DWI) is a main component of multiparametric MRI for prostate cancer detection. Recently, high b value DWI has gained more attention because of its capability for tumor characterization. Objective: To assess based on histopathological findings of transrectal ultrasound (TRUS)-guided prostate biopsy as a reference, an...
متن کاملHigh-b-value diffusion-weighted MR imaging of hyperacute ischemic stroke at 1.5T.
BACKGROUND AND PURPOSE Diffusion-weighted (DW) imaging at b = 2000 s/mm(2) offers theoretical advantages over DW imaging at b = 1000 s/mm(2) for detection of hyperacute ischemic stroke. The purpose of this study was to determine whether b = 2000 images are better than b = 1000 images for detecting and estimating the extent of diffusion change within 6 hours after stroke onset. METHODS We comp...
متن کاملDiffusion-Weighted Magnetic Resonance Imaging for the Evaluation of Prostate Cancer: Optimal B Value at 3T
OBJECTIVE To retrospectively determine the optimal b value of diffusion-weighted imaging (DWI) for predicting the presence of localized prostate cancer, and to evaluate the utility of DWI under different b values in differentiating between cancers and benign prostatic tissues. MATERIALS AND METHODS Eighty patients with suspected prostate cancer underwent MRI including DWI at 3T, followed by r...
