Comparing viscoelastic properties of soft tissues measured in vivo and ex vivo are of interests for basic science and clinical translation. Magnetic resonance elastography (MRE) and indentation are two commonly used techniques for measurement of tissue viscoelasticity. In this study, we used a gelatin phantom to compare measurements by MRE and indentation. Using 2nd-order Prony series, frequency response measured from indentation was estimated. We observed apparent frequency-dependent behaviors from MRE in the range of 50-100 Hz, but not from indentation. Results implied that MRE and indentation measures at different frequency ranges.
