Arterial stiffness is an important marker for cerebrovascular health, as increased stiffness can lead to a range of cerebrovascular pathologies. A non-invasive assessment of cerebral arterial stiffness could therefore be an important imaging marker for cerebrovascular health. Here we show the feasibility of using high field MRI to non-invasively assess cerebral arterial stiffness by measuring the changes in cross-sectional area of the middle cerebral artery throughout the cardiac cycle.
