WebMar 31, 2024 · The shape of the hepatic vein spectral Doppler waveform is primarily determined by pressure changes in the right atrium, or more exactly the blood flow resulting from the resultant pressure gradients. Multiple terms have been used to describe the hepatic vein waveform, including "phasic", "triphasic", "tetrainflectional", and "periodic". Webin the use of waveform terms triphasic, biphasic, and monophasic. How does this statement clarify ‘phasicity’? The term ‘biphasic’, in particular, has sowed confusion amongst ultrasound practitioners.
