Figure 2 Indications for contrast-enhanced ultrasound (US) in radiofrequency (RF) ablation therapy. A: Local tumor progression or residual hepatic malignancies. Contrast-enhanced US shows not only the tumor but also ablated areas as a defect image in the post vascular phase. However, viable tumor is enhanced by reinjection of Sonazoid; B: Hepatic malignancies with severe cirrhotic change. The true malignant tumor was sited among many large regenerated nodules in cirrhotic liver. On contrast-enhanced US, the tumor was distinguishable by reinjection of Sonazoid.

Figure 3 A 66-years-old man with 1. 0 cm hepatocellular carcinoma (HCC) (S3) with liver cirrhosis. A: Contrast harmonic US showed HCC nodule as a defect (arrow) in the post vascular phase after administration of Sonazoid; B: Enhancement (arrow) of HCC was obtained in the defect immediately after reinjection of Sonazoid; C: The defect (arrow) was later exhibited again and the RF electrode needle (arrowheads) was inserted.
