Comparison of (A) T2-weighted anatomical images with whole-brain maps of mechanical properties, (B) storage modulus and (C) loss modulus, from inversion of MRE displacement data captured with the 3D multislab, multishot acquisition. Variations in storage modulus seen in axial slices and sagittal and coronal reformats appear to agree well with neuroanatomy. Visible features include cortical sulci, lateral and fourth ventricles, softer cerebellum, and stiff brainstem. Note that differences in edge profiles are due to data masking required by the finite element meshing process of NLI.
