EXPERIMENTAL: Double dose of Gadopentetate dimeglumine
Subjects with a clinical diagnosis of unilateral Meniere Disease (MD) will undergo 3T MR imaging with a double dose of intravenous (IV) gadolinium contrast injection: 0.2 mmol/kg of Gd-DTPA (Magnevist)

Measure Description |
Time Frame |
|---|---|---|
|
Grade of endolymphatic hydrops (EH) in the cochlea and vestibule
Time Frame: 6 hours after intravenous contrast injection
|
Two Certificate of Added Qualifications (CAQ)-certified neuroradiologists will evaluate the MRI findings.
The degree of EH in the vestibule and cochlea will be classified as "none", "grade I" and "grade II," with grade I being defined as mild and grade II being defined as significant.
