This study aimed to evaluate the effectiveness carcinoma; and safety of multipolar RFA with non-touch technique for hepatocellular carcinoma (HCC) Multipolar 3 cm. radiofrequency Methods: Fifteen cirrhotic patients (9 men, 6 women; age 51e83 years, mean 64.4 years, ablation; Child-Pugh score: A Z 10 and B Z 5) with 17 HCCs of 3 cm (mean: 26 mm), which were diag- Non-touch technique nosed based on typical radiologic findings were enrolled. Two or three Celon Prosurge Bipolar electrodes with 3-cm active tip were deployed with non-touch t
