目的：利用磁共振成像(MRI)显示面神经的增强X线解剖和常见的病理情况。材料和方法：对146例就诊于三级学术咨询中心的患者的面神经MRI表现进行回顾性分析。结果：MRI对面神经的放射解剖和大多数常见的面神经病理情况显示良好。结论：面神经在MRI上的增强应与临床资料相对照。正常人可以表现出鼓室或面神经垂直段的强化。神经迷路部分的强化几乎是贝尔麻痹的诊断。没有观察到肿瘤或中耳或外耳感染的特殊增强模式。为了准确评估多发性硬化症患者的面神经增强，需要进行更大规模的人群研究。(C)2011年皇家放射科医师学会。爱思唯尔有限公司出版。保留所有权利。
AIM: To demonstrate the enhanced radiological anatomy and common pathological conditions of the facial nerve by using magnetic resonance imaging (MRI).MATERIALS AND METHODS: A retrospective review of the MRI findings of the facial nerve of 146 patients who visited a tertiary academic referral center was conducted.RESULTS: The radiological anatomy of the facial nerve was well illustrated using MRI, as were most of the common pathological conditions of the facial nerve.CONCLUSIONS: Enhancement of the facial nerve in MRI should be correlated with the clinical data. Normal individuals can show enhancement of the tympanic or vertical segments of the facial nerve. Enhancement of the labyrinthine portion of the nerve is almost diagnostic of Bell's palsy. No specific enhancement patterns were observed for tumours or for infections of the middle or external ear. A larger population study is required for the accurate assessment of facial nerve enhancement in multiple sclerosis patients. (C) 2011 The Royal College of Radiologists. Published by Elsevier Ltd.
