WebBackground: Diffusion-weighted imaging (DWI) is considered by experts as one of the key elements in multi-parametric magnetic resonance imaging (mpMRI) employed in oncological studies outside the brain. A low-to-high b value ratio DWI has been proposed as an approach to decrease acquisition time and simplify the analysis of DWI data without the … WebObjective: To investigate the value of multi-ultrahigh-b-value diffusion-weighted imaging (UHBV-DWI) in differentiating high-grade astrocytomas (HGAs) from low-grade …
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 … Web13 de abr. de 2024 · Briefly, the mp-MRI protocol included T2WI, DWI, and DCE imaging whereas the bp-MRI protocol included minimally T2WI and DWI. When several DWIs were acquired with different high b values, the DWI score was assessed on a DWI with a b value of 800 or 1000 s/mm 2. ADC maps were acquired using b values of 0 and 800 or 1000 …
WebHeterosis values were calculated on the basis of the parents whose scores were higher (High Parent Heterosis). The results showed that the mean leaf angles of F1 lines from crosses and reciprocal P8IS vs NK212 were the same as the two parents; whereas the P8IS vs NK7328 cross is different.
Web1 de jul. de 2024 · Our study using 3 T scanner and high b-value based DWI and ADC may be an advantage, resulting in more accurate differentiation between ETs, PF-EPNs and PAs. On visual inspection of DWI, all solid components of ETs were high intense at …
