A novel magnetic resonance elastography pulse sequence is introduced that strikes the balance between imaging speed, motion-encoding efficiency and high quality phase images. This pulse sequence was experimentally validated as capable of acquiring full 3D motion-encoding in a volume in less than a minute, and as suitable for mono- and multifrequency MR rheology experiments.
