Fig. 3From: The identification and cognitive correlation of perfusion patterns measured with arterial spin labeling MRI in Alzheimer’s diseaseRegional changes in relative CBF after ANCOVA normalization for the global value in patients with AD in the identification cohort. Cool color indicates regions with relative decreased CBF, and warm color indicates regions with relative increased CBF in AD patients compared to NCs. A threshold of 3.23 (P < 0.001, uncorrected) was used to overlay SPM maps onto a standard MRI brain template. MCC middle cingulate cortex, PCC posterior cingulate cortexBack to article page
