Non-rim arterial-phase hyperenhancement, non-peripheral washout, capsule appearance, tumor margin, corona enhancement, peritumoral enhancement, fat deposition, hemorrhage, and tumor hypointensity on HBP did not statistically significant differences between HCCs with high and low Ki-67 expression in the training set (all P > 0.05, Table 3).
