There were no significant differences in age, gender, origin of liver disease, Child-Pugh score, AFP level, ablation method, early recurrence, median recurrence time, tumor size and tumor number between the two cohorts, so were the MR imaging features including tumor margin, arterial rim enhancement, arterial peritumoral enhancement, satellite nodule, tumor hypointensity on HBP and peritumoral hypointensity at HBP. The gene discussed is AFP; the disease is liver disorder.
