“…Publications in elastography which regard the liver as a poro-elastic Biot medium are scarce and consequently the investigated literature spans includes from anatomy, dynamic mechanical analysis, surgery simulation, tissue engineering and numerical fluid dynamics. In Section 3.1 we confirm the results of [8] who found that the shear wave dispersion in a soft porous material is described by poro-elastic wave propagation theory. This is unambiguously shown by comparing the shear wave dispersion in a soft porous phantom saturated by a Xanthan solution with the dispersion of the same phantom saturated by water.…”

“…Note that [40] finds an equivalence of the Zener and Biot model for low frequency shear waves. However, this does not hold for deviations from Poiseuille flow and Zener's model does not explain the secondary longitudinal wave recently shown in a soft porous tissue [8].…”

“…Recently, we have shown experimentally that Biot's theory of poro-elastic wave propagation well predicts the shear wave dispersion in a melamine sponge [8]. In Biot's theory of poroelastic wave propagation shear wave dispersion is caused by the viscosity of the fluid saturating the connected pore space.…”

“…Similar to [8] we saturate a rectangular Basotect ® melamine resin foam and analyze the shear wave dispersion through the phase velocity measurement of a frequency sweep. Robust results are achieved through ultrafast shear wave imaging of plane shear waves inside the foam.…”

“…where ϕ is the phase, β is the linear slope of the phase, x is the coordinate of the spatial dimension, C is a Constant and ω is the frequency investigated. In contrast to our previous work reported in [8], we perform two experiments that differ only in the viscosity of the saturating fluid. For the high viscosity fluid we choose a 0.1% solution of Xanthan (E415) in water and measure the dispersion at 40°C, where 40°C ensures a good mixing of Xanthan with water.…”

In shear wave elastography, rotational wave speeds are converted to elasticity measures using elastodynamic theory. The method has a wide range of applications and is the gold standard for non-invasive liver fibrosis detection. However, the observed shear wave dispersion of in vivo human liver shows a mismatch with purely elastic and visco-elastic wave propagation theory. In a laboratory phantom experiment we demonstrate that porosity and fluid viscosity need to be considered to properly convert shear wave speeds to elasticity in soft porous materials. We extend this conclusion to the clinical application of liver stiffness characterization by revisiting in vivo studies of liver elastography. To that end we compare Biot’s theory of poro-visco-elastic wave propagation to Voigt’s visco-elastic model. Our results suggest that accounting for dispersion due to fluid viscosity could improve shear wave imaging in the liver and other highly vascularized organs.

Propagation of pore pressure and stress in water-saturated elastic porous media is theoretically investigated when considering the Darcy-Brinkman law. The wave mode, phase velocity, phase lag, damping factor, and characteristic frequency are found from the updated mathematic model. The Brinkman term describes the fluid viscous shear effects and importantly contributes to the dispersion relation and wave damping. The coincidence of the properties of Biot waves of the first and second kinds occurs at a characteristic frequency, which is remarkably influenced by the Brinkman term. A key finding is that, compared to the Darcy-Brinkman law, Darcy’s law overestimates the phase velocity, damping, and phase lag of the first wave, while underestimates the phase velocity, damping, and phase difference of the second wave. The introduction of the Darcy-Brinkman law yields an improved description of the damping of the compressional wave modes in saturated porous media.
