(Top) Transverse color Doppler ultrasound of the right lobe of the liver shows that the right and middle hepatic vein are directed away
from the transducer and flowing toward the IVC. (Middle) Spectral tracing of the right hepatic vein shows a typical triphasic waveform
with A, S, and D waves representing reflection of cardiac motion in the hepatic veins. (Bottom) Spectral tracing of the middle hepatic
vein shows a typical triphasic waveform with A, S, and D waves representing reflection of cardiac motion in the hepatic veins.
