Abstract

The invention disclosed herein provides an example method and system for implementing Selective Spectral Displacement Projection Magnetic Resonance Elastography ("SDP-MRE"), based on simultaneous encoding and acquisition of multiple vibration frequency components using motion encoding gradients (MEG) with different MEG frequencies. A mechanical vibration having multiple vibration frequency components can be induced in an object in a magnetic resonance imaging (MRI) system, while a magnetic resonance (MR) signal is applied to the object. By applying to the object simultaneously in each of three dimensions a MEG having a different MEG frequency component in each of the three dimensions, motion of three different vibration frequency components can be simultaneously encoded into the phase of the MR signal. Three-dimensional, multi-frequency magnetic resonance elastography (MRE) data including the MR signal phase encoded with the three different vibration frequency components can be acquired simultaneously at the multiple frequencies of vibration.
