The extramural venous invasion (EMVI) is considered as the potential prognostic factor for patients with rectal carcinoma. We tried to investigate the diagnostic ability of diffusion kurtosis imaging (DKI) - derived parameters as risk factors for EMVI’s involvement status.Our results showed that the Kmean values, lymph node involvement, and an advanced tumor stage (T3) were independent risk factors for the prediction of EMVI status, which may suggest that the DKI as a potential biomarker for evaluating the EMVI status of rectal cancer is feasible.
