High-resolution MR imaging of the inner ear: findings in Menière's disease.

摘要: Symptoms in Meniere's disease are characterized by hydrops of the endolymphatic system with recurrent rupture membranous labyrinth. The primary cause increased volume appears to be an imbalance between secretion and resorption endolymph which may due obstruction duct sac, located vestibular aqueduct. sac not expected visualized using conventional tomography high-resolution computed (HR-CT), whereas, these identified high resolution MRI (HR-MRI). By HR-MRI, we proposed demonstrate morphological alternation 12 patients disease, this group was compared a 20 healthy subjects. degree visualization on HR-MRI running through aqueduct bony canal assessed. There distinct decrease group. results confirm value technique identify anatomical abnormality, is directly correlated lesion cases unilateral disease.
