Increased free water in the nucleus basalis of Meynert is associated with worse olfaction in idiopathic Parkinson’s disease [PDF]

open access: yesFrontiers in Aging Neuroscience
BackgroundThe association of cholinergic degeneration and olfactory function in Parkinson’s disease (PD) is unclear. Using free water imaging, this study aims to investigate the association between the nucleus basalis of Meynert (NBM) degeneration and ...

Association between perivascular diffusion and white matter microstructural integrity, free water, Aβ burden, and cognition: diffusion tensor vs. kurtosis tensor [PDF]

open access: yesFrontiers in Aging Neuroscience
BackgroundPerivascular diffusion holds great potential for the non-invasive assessment of the glymphatic system (GS). However, Gaussian model-based diffusion tensor imaging analysis along the perivascular space (DTI-ALPS) is limited by microstructural ...

Diffusion tensor free water MRI predicts progression of FLAIR white matter hyperintensities after ischemic stroke

open access: yesFrontiers in Neurology, 2023
BackgroundThe progression of FLAIR white matter hyperintensities (WMHs) on MRI heralds vascular-mediated cognitive decline. Even before FLAIR WMH progression, adjacent normal appearing white matter (NAWM) already demonstrates microstructural ...

Effects of Multi-Shell Free Water Correction on Glioma Characterization

open access: yesDiagnostics, 2021
Diffusion MRI is a useful tool to investigate the microstructure of brain tumors. However, the presence of fast diffusing isotropic signals originating from non-restricted edematous fluids, within and surrounding tumors, may obscure estimation of the ...
