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.
