MR Elastography using a 3T scanner and shear waves of 60 Hz was performed on patients with normal pressure hydrocephalus. A post-processing technique was applied to calculate brain elasticity that included whole brain as well as lobar stiffness. Results demonstrated an increase in brain stiffness of patients with NPH compared with age and sex matched normal controls.
