To explore their potential to detect cortical grey matter pathology we acquired T2 weighted (T2w), T2*w, double inversion recovery, phase-sensitive inversion recovery, and magnetization transfer ratio using fixed post mortem MS brain. Voxels of 0.35mm isotropic gave a clear delineation of the grey matter, both non-lesional and lesional. Our results suggest T2w and T2*w MRI are currently the best techniques to detect cortical grey matter lesions in post mortem MS brain.
