(Top) Longitudinal oblique grayscale ultrasound is shown, centered at the level of the main portal and right portal vein. (Middle)
Longitudinal oblique color Doppler ultrasound, centered at the level of the main portal and right portal vein, shows that flow in the
portal vein is directed toward the liver (hepatopetal). (Bottom) Longitudinal oblique spectral Doppler ultrasound of the main portal
vein shows that the flow is hepatopetal, with gentle undulation reflecting the cardiac and respiratory cycle.
