摘　　要：原发性面肌痉挛是由面神经受到血管压迫引起的面肌异常运动,严重影响患者的生活质量。微血管减压术是目前治疗面肌痉挛最有效的方法。术前对面神经及其周围血管进行高分辨成像,精准定位压迫部位,可以为制订手术计划、预测手术结果提供依据。磁共振神经血管成像序列及后处理技术的发展,为术前判断面神经与血管的关系提供了精准的影像学方法。本文就面肌痉挛患者术前神经血管关系的磁共振脑池成像和血管成像技术、图像重建和融合技术、面神经不同区域受血管压迫的临床表象及神经血管关系与手术预后的相关性进行综述。Primary hemifacial spasm is the abnormal movement of facial muscles caused by the compression of facial nerve by blood vessels,which seriously affects patients’ quality of life.The operation of microvascular decompression is the most effective method to treatment hemifacial spasm.High resolution imaging of the facial nerve and its ambient blood vessels was performed before surgery to accurately locate the compression site,providing the reference for making surgical plans and predicting surgical outcomes.The development of magnetic resonance neurovascular imaging sequence and post-processing technology provides an accurate image method for preoperative judgment of the relationship between facial nerve and vessels.This article reviews magnetic resonance cisternography and angiography techniques,image reconstruction and fusion techniques,clinical manifestations of vascular compression in different areas of facial nerve,the correlation between neurovascular relationship and surgical prognosis in patients with facial spasm.
