Signal 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 کاملRole of Apparent diffusion coefficient value in Diffusion Weighted imaging of MRI to assessment of radiotherapy efficiency in the patient with glioma tumor during treatment
Introduction: Glioma is the most common primary malignancy of cerebral neoplasms in adults, which in spite of therapeutic significant efforts, has a very poor prognosis. The current standard treatment of these patients generally includes surgery and radiotherapy or concurrent chemoradiotherapy with 6 courses of adjuvant use of temozolomide tabs. During these years, the nervous...
متن کاملdiffusion weighted mri for hepatic fibrosis: impact of b-value
background hepatic fibrosis is a typical complication of chronic liver diseases resulting in cirrhosis that remains a major public health problem worldwide. liver biopsy is currently the gold standard for diagnosing and staging hepatic fibrosis. percutaneous liver biopsy; however, is an invasive procedure with risks of complications. therefore, there is need for alternative non-invasive techniq...
متن کاملHigh-b-value diffusion-weighted MR imaging of adult brain: image contrast and apparent diffusion coefficient map features.
BACKGROUND AND PURPOSE Recent improvements in MR gradient technology allow significant increases in diffusion weighting without prohibitive signal-to-noise degradation. The purpose of our investigation was to establish normative references for the signal intensity characteristics and apparent diffusion coefficient values of the adult brain at high b values. METHODS Fifty adults underwent diff...
متن کاملHigh b-value diffusion-weighted MRI of normal brain.
PURPOSE As MR scanner hardware has improved, allowing for increased gradient strengths, we are able to generate higher b values for diffusion-weighted (DW) imaging. Our purpose was to evaluate the appearance of the normal brain on DW MR images as the diffusion gradient strength ("b value") is increased from 1,000 to 3,000 s/mm2. METHOD Three sets of echo planar images were acquired at 1.5 T i...
