A spin-echo sequence with interleaved spiral readouts is implemented for Magnetic Resonance Elastography (MRE) of the brain. This novel sequence allows for high-resolution acquisitions with significantly reduced scan times in order to improve subject comfort. To our knowledge, this is the first implementation of such a sequence, and its performance is demonstrated with both phantom and in vivo brain experiments. This sequence will allow for acquisition of data sets necessary for more sophisticated MRE inversion algorithms while maintaining reasonable acquisition times.
