In Magnetic Resonance Elastography (MRE), mechanical tissue parameters are assessed by sampling shear wave propagation via a set of motion encoded phase offset images. We here investigate a multiple phase offset image acquisition strategy based on displacement encoding with stimulated echoes (DENSE) for multi-slice human brain MRE together with a low frequency mechanical excitation and short echo times. Clear wave images could be acquired using the proposed imaging approach and estimates of the magnitudes of the complex shear modulus could be calculated from the derived wave image data set.
