摘　　要：目的探讨磁共振三维稳态构成干扰序列(3D-CISS)对于血管压迫性三叉神经痛的诊断价值。资料与方法回顾性分析31例经临床诊断为血管压迫性三叉神经痛患者的MR 3D-CISS图像,并与手术结果对照。结果 31例中,术前MR 3D-CISS序列诊断三叉神经脑池段血管接触及受压29例,阳性率为93.5%,手术探查结果30例发现责任血管,3D-CISS序列显示与手术探查符合率达96.67%。结论 3D-CISS序列能较清楚显示血管压迫性三叉神经痛的责任血管及三叉神经受压情况,对于明确病因诊断及决定治疗方法具有重要意义,是目前三叉神经痛术前了解责任血管理想的检查方法。Objective To explore the value of MRI three-dimensional CISS sequence in diagnosis of trigeminal neuralgia caused by vascular compression.Materials and Methods Thirty one patients with trigeminal neuralgia were analyzed retrospectively.The 3D-CISS MR images were compared with the surgical results.Results Preoperative MR 3D-CISS images showed 29 cases（29/31） of trigeminal nerve compression with the positive rate of 93.5%.3D-CISS images had high coincidence with surgical findings.Conclusion 3D-CISS images can clearly show the trigeminal nerve and the vessel compression,which is important for diagnosis and treatment.MR 3D-CISS sequence is an ideal preoperative examination for trigeminal neuralgia caused by vascular compression.
