The purpose of this study was to explore the threshold of IVIM parameters,ADCtotal and ADC(0,500) ratios 24-48 hours after TACE to assess early response in patients with unresectable HCC and to compare the association between diffusion‑weighted imaging with the IVIM-DWI and mRECIST with survival. Our study show that the ADCtotal ratio and D ratio 24-48 hours after TACE were independent predictors for response to TACE for HCC, and showed stronger association with PFS than mRECIST.
