Abstract:
Endolymphatic hydrops can be visualized with high contrast-to-noise ratio even after intravenous injection of single-dose gadolinium-based contrast material (IV-SD-GBCM) using HYDROPS-Mi2 images. We applied 3-dimensional rendering software to process HYDROPS-Mi2 images of 15 ears with and without suspected Ménière's disease and separately visualized the volumes of endo- and perilymph in patients with Ménière's disease even after IV-SD-GBCM. Such dimensional visualization will aid understanding of the pathophysiology of Ménière's disease.
