Abstract

Renal fibrosis threatens kidney viability and fibrosis has been associated with altered tissue structure affecting the biomechanical properties of the kidney, quantifiable as elasticity and viscosity. Importantly, early detection of renal fibrosis may guide therapy and eliminate invasive biopsy procedures. The ability to detect fibrosis early and monitor it regularly with sufficient sensitivity and specificity is an active area of research. A newly emerging method called Shearwave Dispersion Ultrasound Vibrometry (SDUV), that quantifies both elasticity and viscosity by evaluating dispersion of shear wave propagation speed versus its frequency, offers a potential tool to determine renal elasticity and viscosity in vivo. The purpose of this study was to evaluate the feasibility of SDUV for in vitro measurements of renal cortex elasticity and viscosity in the kidney.
