(Top) Longitudinal color Doppler ultrasound of the right kidney shows renal artery branches as red and renal vein branches as blue.
(Middle) In this spectral Doppler waveform of a right segmental renal artery branch, note the low-resistance arterial Doppler waveform
with continuous diastolic flow, similar to that seen in the more proximal renal artery. The venous waveform shows minimal phasicity.
(Bottom) In this spectral Doppler waveform of a right segmental renal vein branch, note the phasic variation in the renal vein, which
can vary depending on systemic venous pressure and cardiac and fluid status.
