Meniere Disease
Conditions
Brief summary
The purpose of this research study is to see if magnetic resonance imaging (MRI) with a double dose of contrast, or dye, and delayed imaging with MRI can help to diagnose Meniere Disease.
Detailed description
Meniere's disease (MD) is a medical condition causing attacks of vertigo, ringing in the ears, hearing loss and often a fullness in the ear. Currently there is no definitive test to diagnose the problem. It is believed to be caused by inner ear abnormalities, specifically of an over-collection of lymphatic fluid.The goal of this trial is to determine if an MRI with double dose of IV gadolinium can be diagnostic.
Interventions
IV administration of 0.2 mmol/kg of Gd-DTPA

Exclusion criteria
* Age \< 18 years * Diagnosis of bilateral MD * History of prior temporal bone surgery * History of cochlear implant placement * Pacemaker, cardiac implantable electronic device, shrapnel, aneurysm clips or other metal objects that are prohibited in the MR suite * GFR \< 90 mls/min/1.73m2 * Cr level \> 1.6 mg/d * Lack of IV access * Contrast allergy to gadolinium agent * Pregnancy * Claustrophobia necessitating parenteral anxiolytics * Patients who are unable to provide informed consent for themselves
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Grade of endolymphatic hydrops (EH) in the cochlea and vestibule | 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. |
