Assessment of Liver Viscoelasticity by Using Shear Waves Induced by Ultrasound Radiation Force

Our preliminary results suggest that Voigt elasticity and viscosity measured between 95 Hz and 380 Hz by using shear wave dispersion ultrasound vibrometry (SDUV) are correlated and that the use of Voigt elasticity measurements from SDUV may not substantially improve performance in liver fibrosis staging compared with the time-to-peak method.
