High b-value dwi
WebObjective: To compare computed high b-value diffusion-weighted images (c-DWI) derived from low b-value DWI images and acquired high b-value DWI (a-DWI), in overall image … WebHigh b-value DWI acquired with NEX=1 and 2 were denoised using the DnCNN network. Experiment was repeated for two dierent slice thicknesses. The results were similar to the gold standard DW image of NEX=4 with 4mm slice thickness. Image entropy that reects the detail in an image was calculated for test and denoised images of 2mm prospective DWI.

WebPurpose . It has been reported that diffusion-weighted imaging (DWI) with ultrahigh b -value increases the diagnostic power of prostate cancer. DWI with higher b -values is challenging as it commonly suffers from low signal-to-noise ratio (SNR), distortion, and longer scan time. The aim of our study was to develop a technique for quantification of apparent diffusion … Webb-value images (b = 1200 s/mm2), apparent diusion coecient (ADC) maps, and computed high b-value images (contrast equivalent to b = 2000 s/mm2) to compare their …
