Figure 3 A 70-year-old man with 1. 5 cm hepatocellular carcinoma after radiofrequency ablation. A: The ablated tumor is depicted as hyper echoic lesion (circle) on B-mode ultrasound (US). However, the boundary between ablated area and unablated liver tissue could not be identified clearly; B: Contrast-enhanced US using Sonazoid shows the defect (arrows) in the Kupffer phase. The ablation margin is shown as low echoic zone surrounding the ablated tumor.
