Pulsatile renal venous waveform
(Top) Transverse split screen showing simultaneous grayscale and color Doppler ultrasound of the right renal hilum is shown. Note that
the right renal artery lies posterior to the renal vein and inferior vena cava. The renal artery normally measures 5-8 mm in caliber.
(Middle) In this spectral Doppler waveform of the right renal artery, note the low-resistance renal waveform with continuous forward
systolic and diastolic flow. Normal PSV ranges from 60-140 cm/s; not more than 180 cm/s. Normal resistivity index is < 0.7 and normal
pulsatility index is < 1.8. (Bottom) Spectral Doppler waveform of the right renal vein is shown, which mirrors the pulsatility in the
inferior vena cava. The renal vein normally measures 4-9 mm in caliber. Normal PSV ranges from 18-33 cm/s.
