There is increasing evidence that neurovascular dysfunction may be a very important risk factor in the development of Alzheimers Disease, an age-related condition. We utilized recently developed Gd-loaded micelles to achieve (100um)3 MR angiograms. Our approach was used to monitor 3D neurovascular changes in individual C57BL/6 wild type mice over one year of normal aging in order to establish a baseline for future research on age-dependent diseases such as Alzheimers Disease.
