Cerebral
blood flow (CBF) has been shown to decline with age and differs between men and
women. However, limited work has been conducted on cognitively unimpaired
subjects. Furthermore, most investigations focus on gray matter (GM), with few results
reported for white matter (WM), in which CBF is lower and represents a particularly
challenging measurement. We investigate associations of age and sex with CBF in
GM and WM regions in a cohort of cognitively unimpaired subjects across a wide
age range. We find significant correlations
between CBF and age, as well as sexual dimorphism of CBF, in critical brain
structures.
