Abstract

To visualize endolymph as bright signal after intravenous injection of single-dose gadodiamide, we shortened the inversion time of heavily T₂-weighted 3-dimensional (3D) fluid-attenuated inversion recovery (FLAIR) to 2050 ms. In 14 patients with suspected Ménière's disease, we observed high signal of vestibular endolymph in all ears, including 6 ears without vestibular endolymphatic hydrops. We observed high signal of cochlear endolymph in 17 ears with cochlear endolymphatic hydrops but not 11 ears without cochlear endolymphatic hydrops.
