Using MRE to evaluate the brain requires acquisition of the full 3D wave field and application of 3D inversion processing to generate valid stiffness maps. The goal of this study was to assess the precision and cross-platform reproducibility of whole brain stiffness measurements obtained with prototype 3D SE-EPI-based MRE techniques, as implemented on GE and Siemens MRI platforms, with the goal of standardization. Our data showed excellent intraplatform repeatability and good interplatform agreement.
