Abstract:
Objective: To investigate the efficacy and safety of MR-guided radiofrequency ablation (RFA) for treatment of hypovascular primary liver cancer. Methods: Totally 21 patients with hypovascular primary liver cancer underwent RFA under guidance of 3.0T MR using MR compatible multipolar RF electrode. Immediate MRI evaluation of the ablated lesions and complications after RFA were performed. One month after operation, plain and dynamic enhanced MR scan of liver were performed, and then reexamination was done every 2-3 months until June 2018. The recurrence rate was observed. Results: A total of 29 lesions were completely ablated among 21 patients assessing by immediate imaging. Complications such as low heart rate, pain and minor hemorrhage etc. occurred in 15 patients (15/21, 71.43%). The follow-up period was 6-26 months (mean [10.23±4.26] months). Local recurrence of ablated lesions was observed in 2 patients (2/21, 9.52%). Conclusion: MR-guided RFA for treatment of hypovascular primary liver cancer is safe and effective with low recurrence rate, which could potentially be applied in clinical practices.
