New measures of response are required that can capture the inherent heterogeneity and the heterogeneous changes observed in soft tissue tumours. Shear-wave Magnetic Resonance Elastography (MRE) measures stiffness of tissue by measuring the propagation of externally applied shear waves. In this study we explore the test-retest repeatability of Multifrequency MRE (MMRE), acquired using an echo-planar imaging readout applied to a soft gelatin phantom used to mimic the stiffness of soft-tissue tumours. Our results suggest MMRE is highly repeatable and supports further investigation in using MMRE to measure response in soft-tissue tumours.
