Microscopic Magnetic Resonance Elastography (μMRE) could be useful in estimating the shear stiffness of biological or other samples of small dimension. In this study, a silicon rubber phantom shell with liquid inside of it was measured using μMRE. A parametric simulation study of a simplified axisymmetric shell model was performed in order to interpret the wave propagation and how it is affected by the material parameter values.
