From: Long segment 3D double inversion recovery (DIR) hypersignal on MRI in glaucomatous optic neuropathy
Bilateral DIR hypersignal in retrobulbar and canalicular optic nerve segments (white arrows on the transverse image reconstruction in a and on the coronal image reconstruction in c) compared to normal DIR hypointense retrobulbar and canalicular optic nerve segments (black arrows with white rim on transverse image reconstructions in b). For comparison hypersignal in the retrobulbar segment is also shown on the coronal T2w m-Dixon turbo spin echo image (white arrows in d)
