High resolution in-vivo measurements of the viscoelastic brain properties in the cerebrum and cerebellum of healthy volunteers were obtained via 3D steady-state Magnetic Resonance Elastography. Coronal plane elastography images were obtained after optimising mechanical excitation and MR sequencing parameters. Quantified grey and white matter results indicate storage moduli are greater in the cerebrum than in the cerebellum. The latest values are lower than previously reported measurements and possible reasons are discussed.
