Ultrasound-guided Percutaneous Radiofrequency Ablation for Hepatocellular Carcinoma

There is still no effective methods of liver cancer.The medical engineering technology has been more applied in the treatment of liver cancer with the rapid development of physics,and the it has played an important role in liver cancer therapy.Radiofrequency ablation is a safe,effective high-temperature physical therapy,guided by the ultrasound or CT,MRI to punct the liver with unipolar or multipolar electrode.The electrode was positioned in the tumor tissue to make the coagulative necrosis and liquefaction necrosis of the tumor tissue to obtain the therapy purpose with radiofrequency.In this paper,ultrasound-guided percutaneous radiofrequency ablation for liver cancer is reviewed.
