Diffusion‐weighted imaging using readout‐segmented echo‐planar imaging, parallel imaging, and two‐dimensional navigator‐based reacquisition in detecting acute optic neuritis

Abstract

Given that its sensitivity and specificity are similar to those of dedicated CET1WI for acute ON, DWI can play an important complementary role in detecting acute ON, especially in atypical ON cases, and can provide a quantitative modality that can be used to evaluate axonal damage in the optic nerves.
