On-resonance variable delay multiple pulse (onVDMP) CEST MRI was applied to detect dynamic D-glucose enhanced signal in brain parenchyma and CSF of 6- and 16-month old APP/PS1 AD mice. A significantly slower D-glucose clearance from CSF was observed in young AD mice compared to age-matched wild type (WT) mice. Moreover, a reduced D-glucose uptake was observed both in parenchyma and CSF of old APP/PS1 mice. D-glucose kinetics detected by onVDMP can be used to assess the alterations in D-glucose uptake and clearance in AD and in the course of AD progression at 3T, a clinical relevant MRI field.
