Abstract

Renal fibrosis threatens kidney viability and fibrosis has been associated with altered tissue structure affecting the biomechanical properties of the kidney, such as elasticity and viscosity. Although there are limited studies regarding viscoelastic properties of renal tissue, an in vivo renal MRE study suggests that shear elasticity changes as a result of hemodynamic variables. A newly emerging method called Shearwave Dispersion Ultrasound Vibrometry (SDUV) offers a tool to determine renal elasticity and viscosity in vivo. SDUV quantifies both elasticity and viscosity by evaluating dispersion of shear wave propagation speed versus its frequency. The purpose of this study is to evaluate the feasibility of SDUV for in vivo measurements of elasticity and viscosity on normal swine kidney consequent to acute changes in renal hemodynamics.
