Fig. 12. A 72-year-old man, referred for post-treatment evaluation (three sessions) by chemoembolization.

In pre-contrast B-mode ultrasonography (A, B, two planes), a hypoechoic nodule is observed in segment VI/VII, with regular contours, with dense peripheral spots, measuring about 7.5×5.0 cm. The contrast-enhanced ultrasonography evaluation shows the absence of arterial contrast (C, D), more evident in the portal (E) and late phases (F), indicating the absence of a viable tumor in the treated nodule. This shows that the treatment was successful.
