Synopsis

Keywords: Cancer, Diffusion/other diffusion imaging techniquesThe prognosis prediction of locally advanced rectal cancer (LARC) was important to individualized treatment, we investigated the performance of ultra-high b-value DWI (UHBV-DWI) in progression risk prediction of LARC and compare with routine DWI. It was found that ADCuh derived from UHBV-DWI performed better than ADC based on routine DWI in predicting prognosis of LARC. The model based on combination of ADCuh, TNM-stage and extramural venous invasion (EMVI) could help to indicate progression risk before treatment.
