Effect of interstitial fluid pressure on shear wave elastography : an experimental and computational study Ghent University
Objective. An elevated Interstitial Fluid Pressure (IFP) can lead to strain-induced stiffening of poroelastic biological tissues. As Shear Wave Elastography (SWE) measures functional tissue stiffness based on the propagation speed of acoustically induced shear waves, the Shear Wave Velocity (SWV) can be used as an indirect measurement of the IFP. The underlying biomechanical principle for this stiffening behavior with pressurization is however ...
