(Top) Transverse grayscale ultrasound of the liver centered at the left hepatic lobe shows the right, middle, and left hepatic veins as
they join into the intrahepatic IVC. (Middle) Transverse color Doppler ultrasound of the liver, centered at the confluence of the hepatic
veins, shows that the flow direction is away from the transducer, directed towards the IVC. (Bottom) Spectral tracing the left hepatic
vein near the confluence with the IVC shows a characteristic triphasic waveform pattern, which represents reflection of cardiac motion.
