Superficial and deep white matter abnormalities in temporal lobe epilepsy.

ABSTRACT: Non-invasive neuroimaging is important in epilepsy to help identify cerebral abnormalities. Abnormally reduced fractional anisotropy (FA) in deep white matter (WM) from diffusion-weighted imaging (DWI) is widely reported in large multi-cohort studies across all types of epilepsies. However, abnormalities in FA for superficial WM are rarely investigated in epilepsy. To gain a greater understanding of the nature of WM abnormality at different WM depths, we investigated DWI abnormalities at a range of superficial and deep WM in two separate temporal lobe epilepsy (TLE) cohorts. The first cohort (TLE = 81, Healthy Control; HC = 67) underwent a high angular resolution multi-shell DWI, whilst the second cohort (TLE = 70, HC = 29) had a single-shell acquisition. We registered FA maps to a standar
