F2 and hepatocellular carcinoma: In multivariate logistic regression analysis, tumor size > 2 cm (P = 0.024, OR 3.05, 95% CI 1.19–11.13), Prothrombin induced by vitamin K absence-II > 32 mAU/ml (P = 0.001, OR 4.13, 95% CI 1.23–11.38), irregular tumor margin (P = 0.018, OR 3.10, 95% CI 1.16–8.31) and apparent diffusion coefficient value < 1007 × 10− 3mm2/s (P = 0.035, OR 2.27, 95% CI 1.14–7.71) were independent risk factors correlated to MVI in HCC.
