This study selected 48 HCC patients admitted to our hospital from January 2018 to June 2019, and divided them into 34 HCC patients in the MVI negative group and 14 HCC patients in the MVI positive group according to the postoperative pathological results. And then the round area of ROI was used to measure the lesion on the IVIM image. Finally, the diagnostic value of D, D*, f and ADC to MVI was analyzed by statistical software. The results showed that IVIM-DWI was helpful in evaluating the MVI of HCC, and D value had the best diagnostic efficacy.
