Brain-age estimates the biological brain age from structural MRI images based on changes in brain-tissue integrity and irreversible
structural changes [1]. The brain-age offset to the chronological age — the age gap — is associated with cognitive pathology [2]. Adding
vascular or functional MRI biomarkers may add sensitivity to physiological and metabolic changes, complementing and improving structural
brain-age, and possibly improving its sensitivity to earlier disease changes. Arterial spin labeling (ASL) MRI is a potential early biomarker of
cerebrovascular health and correlates with the initial stages of cognitive pathology [3]. Here, we propose the ‘Cerebrovascular Brain-age’ as a
combination of T1w, FLAIR, and ASL image features composed of the spatial Coefficient of Variation (CoV) and vascular-territory derived
(VT) cerebral blood flow (CBF).
