感音神经性听力损失患者MRI特征

MRI Features of Patients with Sensorineural Hearing Loss

摘要:

感音神经性听力损失（SNHL）是耳科常见疾病，主要表现为听力损失伴或不伴耳鸣、眩晕、耳闷等症状，SNHL病因复杂多样，目前尚未有一个确切的病因。近年来磁共振影像技术的发展和运用，为SNHL病因的探索提供了新思路。内听道磁共振成像在显示软组织方面更具优势，可用来研究SNHL患者的内耳疾病，如研究小脑前下动脉来进一步阐述内耳微循环，轧造影显示梅尼埃病患者膜迷路积水，以及功能磁共振成像对脑区活动的研究。

Abstract:

Sensorineural Hearing Loss (SNHL) is a common disease in otology, which mainly manifests as hearing loss with or without tinnitus, vertigo and stuffy ears, etc. The etiology of SNHL is complex and diverse, which is no clear cause at present. In recent years, with the development and use of magnetic resonance imaging technology, new ideas have been provided for the exploration of the cause of SNHL.Magnetic resonance imaging of the internal auditory tract is more advantageous in showing soft tissue and can be used to study inner ear disease in patients with SNHL, such as studying the anterior inferior cerebellar artery to further elucidate inner ear microcirculation, ginography to show membrane vagal effusion in patients with Ménière's disease, and functional magnetic resonance imaging to study activity in brain regions.
