Hemodynamic and morphologic changes of peripheral hepatic vasculature in cirrhotic liver disease: A preliminary study using contrast-enhanced coded phase inversion harmonic ultrasonography

Figure 3 Contrast-enhanced US images in normal controls. A: In the early arterial phase, only the peripheral arteries were displayed, they were thin and regular; B and C: In the vascular phase of contrast-enhanced US, the peripheral portal vein (B) and hepatic vein (C) were portrayed as regular in caliber, course, and ramification, tapering smoothly as they run to the liver surface.
