Disentangling characteristics of subpial lesions in multiple sclerosis using multiparametric postmortem MRI
We have characterized the imaging correlates of subpial demyelination in the cerebral cortex of MS patients by exploiting multiparametric postmortem qMRI and histopathology. MTsat, qT1 and AD were the measures that best captured subpial lesions pathology. Additionally, we found that some subpial lesions exhibit a juxta-cortical rim of increased susceptibility and show lower MWF than the ones without rim.
