Synopsis

Keywords: Urogenital, Diffusion/other diffusion imaging techniquesAccurately determining the histologic grade and variant status is essential. In this study, the diagnostic value of the CTRW model in characterizing histological grade or histological variants was evaluated and compared with ADC. The optimal diagnostic performance of CTRW diffusion model suggested it could provide more diagnostic value than conventional ADC not only for pathological grading but also for histological variant of bladder urothelial carcinoma.
