HCC is one of most common causes of cancer-related death in the world due to lately diagnosis by typical hallmarks which rely on completed arterialization. So it is important to earlier diagnose and treat hypovascular early HCC(eHCC). The aim of this study is to evaluate the efficacy and safety of microwave ablation for early HCC, also to explore the feasibility of EOB-MRI (Gd-EOB-DTPA enhanced MRI) guided ablation.

Inclusion Criteria:

1. Age ≥ 18 years;
2. Patients with chronic liver disease who are at high/extremely high-risk of hepatocellular carcinoma;
3. EOB-MRI suggestive of confirmed or suspected eHCC (single lesion ≤ 2 cm or number of lesions ≤ 3 and maximum diameter ≤ 2 cm)
4. No previous history of hepatocellular carcinoma;
5. Not receiving any anti-cancer treatment;
6. Liver function Child-push A or B.

Exclusion Criteria:

1. Presence of lymph nodes or distant metastases;
2. Presence of liver metastases;
3. Prior malignancy;
4. Severe cardiopulmonary or renal dysfunction;
5. Suffering from uncorrectable coagulation dysfunction (prothrombin time > 25 seconds, prothrombin activity < 40%, platelet count ≤ 50x10^9/L);
6. Severe infectious lesions in the area of the puncture needle tract.

Patients with chronic liver disease at high-risk or extremely high-risk of hepatocellular carcinoma and EOB-MRI shows a confirmed or suspected eHCC.
