Short summary
Intrathecal contrast-enhanced MRI (gMRI) shows limited association with Diffusion Tensor Image Analysis Along Perivascular Spaces (DTI-ALPS) in measuring glymphatic function, suggesting DTI-ALPS may not be a reliable proxy for gMRI-assessed glymphatic function.

Key points
- Intrathecal contrast-enhanced MRI (gMRI) showed sparse contrast enhancement in ALPS regions across all groups.
- The association between the ALPS index and gMRI markers of glymphatic function was limited.
- DTI-ALPS may not be a reliable surrogate for gMRI-assessed glymphatic function.
