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 کاملSignal to noise ratio of high b-value diffusion weighted images is improved using computed diffusion weighted imaging
acquired (+) and computed DWI imaging (x) where the acquisition time is kept the same for both. It is seen that noise remains constant across b-values for the conventionally acquired images whereas for cDWI it reduces with b-value as predicted by equation 1 (dotted curve). It is seen that for high b-values (>700 s mm) the SNR of cDWI is improved compared to conventional imaging. Figure 1. An ex...
متن کاملAssessment of image-based registration of diffusion-weighted images acquired at high b-value
S. Muñoz Maniega, M. E. Bastin, P. A. Armitage Medical and Radiological Sciences (Medical Physics), University of Edinburgh, Edinburgh, Scotland, United Kingdom, Clinical Neurosciences, University of Edinburgh, Edinburgh, Scotland, United Kingdom Introduction There is growing interest in the use of high b-value diffusion MRI to model complex white matter fibre structures in the brain. One disad...
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...
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...
