High resolution MR-elastography is applied to image the mechanical properties of mice brain in particular the corpus callosum at 1000Hz. A reproducibility study shows that the obtained values for the complex shear modulus are stable (Gd:7%, Gl:25%) and that also other myelinated structures are well visible like the optic tract or the superior cerebellar peduncle.
