Fig. 3. A representative example of a MicroFlow Imaging examination in a 66-year-old man with hypervascular hepatocellular carcinoma.

This patient had a 7.1-cm tumor in the left lateral segment of the liver. A, B. On color Doppler imaging (A) and power Doppler imaging (B), vascularity is demonstrated only along the periphery. Both radiologists assessed this tumoral vascularity as a basket pattern. C, D. MicroFlow Imaging examination reveals a mixed pattern of vascularity, combining the basket and vessels-in-tumor patterns (C), which is confirmed on a contrast-enhanced ultrasound examination (D).
