Abstract

Lots of recent technical advances in radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) have introduced. First, contrast-enhanced ultrasound can help to detect the index tumors, residual tumor, and local recurrence. After contrast-enhanced ultrasound for subtle small tumors, we can perform RFA with high confidence. The use of artificial ascites in RFA is a simple and useful technique to minimize collateral thermal injury and to improve the sonic window. Fusion imaging between US and CT or MR during RFA is useful since US can provide real-time imaging and CT or MR provides high quality images with good contrast and spatial resolution. RFA can be performed with fluoroscopy guidance to lipiodol retention tumors.
