Doppler ultrasound of the hepatic veins: normal appearances
Abstract
Doppler ultrasound of the hepatic veins gives a pulsatile velocity profile which mirrors the cardiac cycle. We describe the physiological basis for the complex waveform and suggest a venous pulsatility index (VPI) which can be used to quantify it. We have studied normal volunteers under differing conditions to establish a normal range of VPI. This provides a baseline against which abnormal patterns of hepatic vein Doppler can be judged.
