MR Elastography (MRE) is an emerging imaging technique used to quantify the stiffness and viscosity of tissue. Few studies have investigated the relationship between these biomechanical properties and brain perfusion. If understood, this could provide valuable new insight in diseases that alter biomechanical properties or functionality. In our study we assess the cerebral blood flow and the tissue stiffness of gray matter in healthy volunteers. We find that in cortical gray matter, both the cerebral blood flow and the shear storage modulus G’ was higher than in deep gray matter.
