Figure 2 A patient with right-sided acute optic neuritis. (A) A T2-weighted fat-suppressed image, displaying a swollen and hyperintense right optic nerve. (B) Marked enhancement of the optic nerve is noted on post-enhanced fat-suppressed T1-weighted image. (C) Diffusion-weighted imaging, showing a strikingly hyperintense right optic nerve.
