摘　　要：目的本文主要讨论平衡扰相梯度回波(B-FFE)与三维快速高级自旋回波(3D FASE)对面神经及邻近血管间的关系评价情况。方法选取2015年4月至2017年9月间于我院检查治疗的面肌痉挛患者共92人进行回顾性分析,采用随机数字表法随机分为B-FFE组及3D FASE组,每组各46人。观察组患者行磁共振B-FFE序列扫描,对照组患者行3D FASE序列进行扫描,根据扫描结果分析各组患者的面神经及其邻近血管的显示情况。结果 B-FFE组有38例患者存在神经压迫,3D-FASE组有40例患者存在神经压迫,在诊断灵敏度(χ~2=7.236,P=0.011)、诊断准确度(χ~2=6.389,P=0.021)、阴性预测值(χ~2=4.626,P=0.046)比较中,具有统计学意义;B-FFE组在神经显示评分、血管显示评分及邻近血管来源显示评分上均高于3D FASE组,差异具有统计学意义(P<0.05)。在手术确诊患者中,两种诊断方法的诊断符合率比较,具有显著性差异(χ~2=7.236,P<0.05)。结论磁共振B-FFE序列较3D FASE序列能更为清晰、准确地显示面神经或三叉神经与临近血管间的关系,且经手术证实的诊断符合率也较高,值得于临床诊断中推广使用。Objective This article aimed to discuss the balance one phase gradient echo(B-FFE)and senior 3D fast spin echo(3D FASE)across the nerve and the relationship between adjacent vascular evaluation.Methods A total of 92 patients with facial spasm during April 2015 and September 2015 in our hospital were retrospectively analyzed in this study.According to random number table method,patients were randomly divided into B-FFE group and 3D FASE group,with 46 patients in each group.The scanning result of facial nerve and its adjacent blood vessels display were compared between the two groups.Results In the B-FFE group,38 patients showed nerve compression,while in the 3D-FASE methods,there were 40 patients with nerve compression,there was statistical significance in the diagnostic sensitivity(c2=7.236,P=0.011),diagnostic accuracy(c2=6.389,P=0.021),and negative predictive value(c2=4.626,P=0.046).There was a statistically significant difference(P<0.05)in terms of nerve display scores,vascular display scores,and adjacent vascular origin scores between two methods.In the surgically diagnosed patients,there was significant differences(c2=7.236,P<0.05)in the diagnostic accuracy rates of the two diagnostic methods.Conclusion MRI-compared with 3D B-FFE sequence,the FASE sequence can more clearly and accurately show the facial nerve or the relationship between trigeminal nerve and adjacent vessel,with high diagnosis coincidence rate.So it is worth to be used widely in clinical diagnosis.
