We describe a full field-of-view rapid gradient echo based technique suitable for magnetic resonance acoustic radiation force imaging with a 7 s temporal resolution, and the validation of the method in a gel phantom. The propagation of the displacement wave emanating from the ultrasound focus within the phantom material was clearly captured by the method described. The potential to measure the displacement wave speed in phantom experiments may pave way toward estimating phantom mechanical properties.
