Among them, 34 patients with 35 liver tumors underwent percutaneous RFA under combined US/CT guidance, and 31 patients with 35 liver tumors received percutaneous RFA under CT guidance alone. The efficacy of combined US/CT-guided RFA was analyzed, and the procedure time and safety between the two groups were compared.Results: In the combined US/CT-guided RFA group, the 1-, 3-, and 5-year local recurrence rates were 3%, 6%, 9%, respectively, and the 1-, 3-, and 5-year overall survival rates were 100%, 97%, 94%, respectively. The mean procedure time in the CT-guided RFA group was significantly longer than that of the combined US/CT-guided RFA group (P
