In this novel study, magnetic resonance elastography (MRE) of the liver is simulated in a detailed 3D anthropomorphic finite element model of the human torso, to explore the influence of imaging spatial resolution and motion-based signal to noise ratio (SNR) on the accuracy of elastograms calculated by direct inversion. It was found that MRE accuracy was highly dependent on imaging voxel dimensions, motion-SNR and the ground truth material properties. These findings will guide the optimisation and development of future liver MRE methodology.
