White matter geometry confounds Diffusion Tensor Imaging Along Perivascular Space (DTI-ALPS) measures

Radial diffusivity asymmetry driving DTI-ALPS indices pervades white matter, persists at high b-values, and tracks crossing fibers, axonal undulation and dispersion rather than perivascular diffusion.
