Fig. 1From: Increased cortical lesion load and intrathecal inflammation is associated with oligoclonal bands in multiple sclerosis patients: a combined CSF and MRI study3D double inversion recovery images of three RRMS OCB+ patients (a–c) and three RRMS OCB− patients (d–f). OCB+ patients show both white and grey matter demyelination (arrows) including insular lesions (arrows, c). OCB− patients do not show any grey matter lesion despite the severe white matter demyelination especially in the periventricular region (arrowheads, d–f)Back to article page
