MRI在显示腮腺内面神经中的应用进展

Application progress of MRI in demonstrating the facial nerve in the parotid gland

腮腺内面神经走行复杂,与周围解剖结构难以分辨,是影像成像的难题。随着磁共振神经成像(magnetic resonance neurography,MRN)序列的应用,解剖相关MRN及功能性MRN等技术对腮腺内面神经进行成像,提高了显示率,为明确神经来源病变及评估面神经与周围病变的关系提供了帮助。本文就近年来腮腺内面神经MRN成像技术及其临床应用予以综述,旨在为腮腺内面神经MRN的完善提供多角度信息。

The facial nerve in the parotid gland has a complex course and is difficult to distinguish from the surrounding anatomical structures.With the application of magnetic resonance neurography(MRN)sequences,anatomical MRN and functional MRN techniques were used to demonstrate the facial nerve in the parotid gland,which improved the demonstration rate,and helped for identifying the neural lesions and evaluating the relationship between facial nerve and peripheral lesions.This article reviews the MRN imaging technique of facial nerve in parotid gland and its clinical application in recent years,aiming to provide multi-angle information for the improvement of MRN in parotid segmental facial nerve.
