The Importance of the Temporal Bone 3T MR Imaging in the Diagnosis of Menière's Disease

Background: The aim of this study was to evaluate endolymphatic hydrops using the 3T temporal bone magnetic resonance imaging (MRI), performed according to the chosen protocol, and determine whether it could be applied as an objective diagnostic tool for Menière's disease. Methods: 105 participants diagnosed with probable (n = 50) and definite (n = 55) Menière's disease were included in this prospective study at Vilnius University Hospital, Santaros Clinics. Audiometry, vestibular function tests, videonystagmography, and computer posturography were performed before MRI. The 3T MRI with gadolinium contrast was performed to evaluate the endolymphatic hydrops. Imaging protocol consisted of 3D-FLAIR and 3D T2DRIVE sequences. Vestibular endolymphatic sac was interpreted as enlarged if occupied more than 50% of the vestibular area. Results: 78.1% of subjects had abnormal MRI findings other than hydrops, and it was more than 90% (50/55) of patients in the definite MD group (p
