Abstract
The visualization of the morphologic substrate of Meniere’s disease -the endolymphatic hydrops – can be performed using non-contrast as well as contrast-enhanced magnetic resonance imaging techniques. The non-contrast magnetic resonance imaging technique uses a heavily T2-weighted sequence; however, the reproducibility of this technique remains to be confirmed. The contrast-enhanced techniques most frequently use a 3-dimensional fluid-attenuated inversion recovery sequence or a real 3-dimensional inversion recovery sequence either after intratympanic gadolinium administration either 4 hours after intravenous gadolinium administration. The latter is the most frequently used technique and is able to detect definite Meniere’s disease with a high sensitivity and specificity. It has been proven to be a reliable technique with a high diagnostic accuracy, enabling the visualization of endolymphatic hydrops.
Highlights
Menière’s disease (MD) is a chronic disease with a reported prevalence of 17–513 patients per 100,000 [1]
More than 150 years ago, Prosper Menière was the first to recognize the inner ear as the site of origin for this disease [3]
Hallpike pointed out the endolymphatic hydrops (EH) as the pathological counterpart for MD [4]
Summary
Menière’s disease (MD) is a chronic disease with a reported prevalence of 17–513 patients per 100,000 [1]. The cochlear duct, the saccule, the utricle or ampullae contain endolymph. MR Methods for the Visualization of Endolymphatic Hydrops Recent developments of high-resolution MR imaging of the inner ear have enabled us to visualize in vivo EH in patients with suspected MD.
