In MRE, motion encoded phase images are acquired to calculate mechanical tissue parameters based on shear wave propagation. We here propose a fast multi readout MRE imaging concept based on the displacement encoding via stimulated echo acquisition (DENSE). In this proof of concept study, phantom experiments yielded excellent clear wave images. The results indicate that the proposed technique could be used to acquire images using short echo times and accelerate the total acquisition time of MRE examinations.
