Contrast-Enhanced Ultrasound in Residual Tumor of Hepatocellular Carcinoma following Transarterial Chemoembolization: Is It Helpful for Tumor Response?

<div>36-year-old man with 4.0 cm×2.8 cm lesion. CEUS images in this large tumor showed peripheral enhancement in the arterial phase (a) and washout in the portal venous phase (b) (cross mark). Percutaneous needle-biopsy results (c) showed the necrotic area (black arrows) and residual tumor (red arrows) which was positive at CD34 staining (d).</div>
