Comparison of a single slice of MRE data captured using (top row) an equivalent 2D acquisition for comparison with (bottom row) the 3D multislab acquisition on the same subject in the same imaging session: (A/B) magnitude image from MRE acquisitions; (C/D) corresponding captured z-displacements; (E/F) storage modulus property maps; and (G/H) loss modulus property maps. The data acquired in 2D is much noisier and has an OSS-SNR value below the minimum needed for inversion. The excessive noise of the 2D acquisition produces property maps lacking the fine-scale features of the maps calculated from 3D multislab displacement data, most noticeably the lateral ventricles. Note the contrast difference between magnitude images is due to the different TR of the acquisitions.
