Synopsis

To assess the cerebral microvascular alteration in the demented patients relative to a non-demented population using in vivo microvascular index maps by using Gd-based contrast agent at a 3T MRI system, we included 11 non-demented participants and 11 AD patients. Compared with the non-demented group, BVf and MvWI were significantly increased in the demented group. Both mVD and VSI were only significantly decreased in the demented group at the white matter hyperintensity (WMHI) area. BVf and MvWI were significantly positively correlated with age and VSI was significantly positively correlated with MMSE.
