Three-Dimensional Magnetic Resonance Imaging Reveals the Relationship Between the Control of Vertigo and Decreases in Endolymphatic Hydrops After Endolymphatic Sac Drainage With Steroids for Meniere's Disease

Frontiers in Neurology, 2019
Meniere's disease is a common disease, that presents with recurrent vertigo and cochlear symptoms. The pathology of Meniere's disease was first reported to involve endolymphatic hydrops in 1938. The endolymphatic sac is thought to have a role to keep the

Gray‐tone appearances on 4‐hour delayed gadolinium‐enhanced magnetic resonance imaging indicate severe inner ear pathology and symptoms in sudden sensorineural hearing loss

Laryngoscope Investigative Otolaryngology
Objective Hybrid of reversed image of positive endolymph signal and negative image of perilymph signal (HYDROPS) in delayed gadolinium‐enhanced magnetic resonance imaging (MRI) typically depicts normal inner ear as “white‐tone” and endolymphatic hydrops ...

Perilymphatic enhancement and endolymphatic hydrops: MRI findings and clinical associations. [PDF]

Laryngoscope Investig Otolaryngol
The relationship between the signal intensity ratio (SIR) of PE and hearing changes (A) and vertigo attacks (B) within 6 months in patients with MD is shown. SIR was significantly higher in the group experiencing changes within 6 months compared with the group that did not experience change.

Effects of Intratympanic Injection of Isosorbide on the Vestibular Function of Animal Models of Endolymphatic Hydrops [PDF]

Clinical and Experimental Otorhinolaryngology, 2021
Objectives The aims of this study were to investigate the effects of intratympanic injections of isosorbide on vestibular function in animal models of endolymphatic hydrops and to find a new treatment option for the acute onset of vertigo in Ménière ...

Semi-quantitative vs. volumetric determination of endolymphatic space in Menière's disease using endolymphatic hydrops 3T-HR-MRI after intravenous gadolinium injection. [PDF]

PLoS ONE, 2015
Magnetic resonance imaging enhances the clinical diagnosis of Menière's disease. This is accomplished by in vivo detection of endolymphatic hydrops, which are graded using different semi-quantitative grading systems.

Automated Methods for Detecting and Quantitation of Enlarged Perivascular spaces on MRI

Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 11-24, January 2023., 2023
The brain's glymphatic system is a network of intracerebral vessels that function to remove “waste products” such as degraded proteins from the brain. It comprises of the vasculature, perivascular spaces (PVS), and astrocytes. Poor glymphatic function has been implicated in numerous diseases; however, its contribution is still unknown.
