Can IVIM help predict HCC recurrence after hepatectomy?

ConclusionTheD value derived from the IVIM model is a potential biomarker for the preoperative prediction of recurrence after hepatectomy in patients with HCC. When combined with age and AFP levels,D can improve the predictive performance for tumor recurrence.Key Points• The recurrence rate of HCC after hepatectomy was higher in patients with ADC, D, and f values that were lower than the optimal cutoff values.• The optimal cutoff values of ADC, D, D*, and f for predicting recurrence in HBV associated HCC were 0.858 × 10−3 mm2/s, 0.985  × 10−3 mm2/s, 12.5  × 10−3 mm2/s, and 23.4%, respectively.• The D value derived from IVIM diffusion-weighted imaging may be a useful biomarker for preoperative prediction of recurrence after hepatectomy in patients with HCC. When combined with age and AFP levels, D can improve the predictive performance for tumor recurrence.
