Abstract
≥ .55). Conclusion CSF tracer enhancement in the ALPS regions of interest was sparse across groups, and the association between the ALPS index and gMRI markers of glymphatic function was limited. © The Author(s) 2026. Published by the Radiological Society of North America under a CC BY 4.0 license.
