Multiscale white- and gray-matter diffusion abnormalities and their associations with serum ammonia in hepatic encephalopathy: a free-water elimination diffusion MRI study.

The findings indicate coexisting white- and GM diffusion abnormalities in HE and distinct within-HE associations between serum ammonia and selected diffusion metrics, which provide complementary estimates of free-water fraction and tissue-specific diffusion.

Imaging study of white matter microstructural damage and glymphatic system dysfunction in patients with primary insomnia: a combined analysis based on PSMD, DTI-ALPS, and EPVS

Primary insomnia was associated with greater white matter microstructural heterogeneity, whereas evidence of glymphatic dysfunction was partial and indirect, and higher PSMD was related to glymphatic-related imaging markers and poorer cognitive performance; however, the small sample and cross-sectional design warrant c...

White and gray matter diffusion-derived differences in type 2 diabetes mellitus: a free-water-corrected diffusion MRI study.

Background Type 2 diabetes mellitus (T2DM) is frequently accompanied by complex brain microstructural abnormalities and cognitive decline. Conventional diffusion tensor imaging (DTI) metrics can reflect both tissue diffusion properties and extracellular free-water effects, complicating the interpretation of T2DM-relate...

Tissue-specific diffusion abnormalities and localized free-water reductions in hypertension despite no detectable group difference in the DTI-ALPS index

In HTN, tissue-specific diffusion abnormalities and localized fluid shifts are detectable even in the absence of statistically significant group differences in the DTI-ALPS index, indicating that FWE metrics may serve as sensitive neuroimaging indicators for evaluating hypertensive brain involvement.
