Association of MRI indices of glymphatic system with amyloid deposition and cognition in mild cognitive impairment and Alzheimer disease
Background and Objectives The glymphatic system is a whole-brain perivascular network,
which promotes CSF/interstitial fluid exchange. Alterations to this system may play a pivotal …
