Journal Article
Hu, J., Craig, M. S., Knight, S. P., De Looze, C., Meaney, J. F., Kenney, R. A., Chen, X., & Chappell, M. A. (2025). Regional changes in cerebral perfusion with age when accounting for changes in gray-matter volume. Magnetic Resonance in Medicine, 93(4), 1807-1820. https://doi.org/10.1002/mrm.30376

Purpose
One possible contributing factor for cerebral blood flow (CBF) decline in normal aging is the increase in partial volume effects due to brain atrophy, as cortical thinning can exacerbate the contamination of gray-matter (GM) voxels by other...
