摘　　要：目的 :分析MRI三维稳态构成干扰序列(3D-CISS)对三叉神经脑池段的显示、走行及与周边血管关系的表现,探讨3D-CISS对血管压迫性三叉神经痛的诊断价值。方法 :回顾性分析29例经神经外科手术证实的血管压迫性三叉神经痛患者的MRI表现,观察三叉神经的形态、走行及其与血管关系。结果 :三叉神经在3D-CISS序列显示清晰,显示率为100%,29例均显示局部动脉接触或压迫三叉神经,且经手术证实;结合3D-TOF-MRA分析显示责任血管,27例为同侧小脑上动脉,1例为同侧椎动脉,1例为同侧基底动脉。结论:MRI 3D-CISS能清晰显示三叉神经脑池段形态、走行及其与周边血管的关系,结合3D-TOF-MRA有助于确定责任血管,对术前评估和指导治疗有重要意义。Objective：To evaluate MRI findings and diagnostic value in the vascular compression of trigeminal neuralgia. Methods：MRI manifestations and operative results of 29 patients with vascular compression of trigeminal neuralgia were retrospectively reviewed,observed the shape of trigeminal nerve and the course of it,and according to the MPR and MIP multi-angle showed the relationship between trigeminal nerve and blood vessels. Results：In 3D-CISS sequence,trigenfinal nerve was clearly shown,with a rate of 100%. 29 patients all showed that the trigeminal nerve contacted or was compressed by local artery, which were proved by nerve surgery;combined with 3D-TOF-MRA sequence analysis shows responsibility blood vessels,27 cases of ipsilateral superior cerebellar artery,1 case of ipsilateral vertebral artery,1 case of ipsilateral basal artery. Conclusion： 3D-CISS imaging sequence could clearly demonstrate the shape or the course of the intracisternal segment of the trigeminal nerve and adjacent vessels,combined with 3D-TOF-MRA sequence analysis shows responsibility blood vessels,and it plays an important role in preoperative evaluation and treatment.
