This study investigated the role of RESOLVE and TGSE DWI sequences in the evaluation of optic neuritis and compared their image qualities qualitatively and quantitatively. We found that TGSE significantly improved the image quality for the evaluation of optic neuritis by reducing the susceptibility induced image distortion compared with RESOLVE. However, it appeared lower SNR and CNR than that of RESOLVE images.
