Combined ultrasound/computed tomography guidance in percutaneous radiofrequency ablation after transarterial chemoembolization for hepatocellular carcinoma in the hepatic dome

摘要

PurposeTo assess the value of the combined ultrasound (US)/computed tomography (CT) guidance (US guidance was firstly used for puncture with the electrode needle to the site close to the tumor, and subsequently, CT guidance was used for precise positioning of the electrode tips) in percutaneous radiofrequency ablation (RFA) after transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) in the hepatic dome.
