Three-Dimensional Volumetric Measurement of Endolymphatic Hydrops in Meniere's Disease

Objective: We used volumetric three-dimensional (3D) analysis to quantitatively evaluate the extent of endolymphatic hydrops (EH) in entire inner ear. tested for correlations between planimetric and measurements, identify their advantages disadvantages. Methods: HYDROPS2-Mi2 EH images were acquired 32 ears (16 patients): 16 ipsilateral MD patients (MD-ears) contralateral ears. Three-T MR unit with a 32-channel phased-array coil/the contrast agent fill perilymphatic space sequence. calculated EH% [(endolymph)/(endolymph+perilymph)] ratio analyzed ear terms value, but only single cochlear vestibular slices subjected evaluation. The values compared non-MD ears, diagnostic accuracy two methods. Results: was significantly higher vestibules (50.76 ± 13.78%) than (39.50 8.99%). also (61.98 20.65%) (37.22 12.95%). correlated Conclusion: Volumetric measurements facilitate diagnosis Both methods seem be reliable consistent; this study. However, overestimates by 26.26%. Also, data may not correlate cochleae normal values.
