Figure 4 Post procedural contrast enhanced ultrasound (20 min after microwave ablation) in a 72-year-old man with chronic hepatitis C virus-related hepatocellular carcinoma. Reactive hyperemia achieved immediately after the procedure (22 s). A: Thick and regular rim of arterial phase hyperenhancement surrounds the treatment area (arrows); B: Absence of wash-out in the late phase (4 min) confirms the reactive significance of hyperemia.
