Figure 1 B-mode ultrasound, contract-enhanced ultrasound and ultrasound localized microscopy (ULM) imaging. (A) B-mode ultrasound shows an oval mass (blue arrow) in segment II. (B, C) On color Doppler flow imaging, peripheral vessels (green arrow) are seen around the mass (yellow circle), with no significant internal vascularity. (D–G) Contrast-enhanced ultrasound (CEUS) images of the mass. (D–F) images correspond to the early arterial phase (11 s), late arterial phase (22 s), portal phase (50 s), and delayed phase (139 s), respectively. The lesion shows arterial phase hyperenhancement followed by hypoenhancement in the portal and delayed phases. In the arterial phase (D), tortuous microvessels within the tumor (white arrow) and surrounding annular vessels (red arrow) are visible. (H, I) ULM images demonstrate characteristic staghorn-shaped vessels within the lesion (white arrow). (H) Blood flow velocity map; (I) blood flow direction map.
