Spectral tracing of left portal vein
(Top) Transverse grayscale ultrasound of the left lobe of the liver is shown, centered at the left portal vein. (Middle) Transverse color
Doppler ultrasound of the left lobe of the liver is shown, centered at the level of the left portal vein. Flow in the left portal vein is
directed towards the transducer, indicating that the flow is hepatopetal and therefore normal. (Bottom) Spectral tracing of the left
portal vein on this transverse pulsed Doppler ultrasound shows that the flow is monophasic, directed towards the transducer, with a
mildly undulating waveform related to slight transmission of the cardiac cycle, which is a normal appearance for the portal vein.
