摘　　要：目的：探讨 MR 三维高分辨率成像曲面重建（CPR）联合仿真内窥镜重建（MRVE）在血管压迫性三叉神经痛（TN）中的应用。方法对65例 TN 患者采用 MR 三维双激发平衡式稳态自由进动序列（3D-FIESTA-C）扫描,运用 CPR 联合 MRVE 评价患侧血管神经解剖关系,其中60例与微血管减压（MVD）手术结果比较。结果65例3D-FIESTA-C CPR 联合 MRVE 显示责任血管阳性率为92.3%（60/65）,其中60例与手术结果比较,3D-FIESTA-C CPR 联合 MRVE 在显示责任血管以及压迫部位方面与 MVD有较好的一致性,其诊断符合率为95%（57/60）。结论MR 三维高分辨率成像 CPR 联合 MRVE 能够较为清晰、准确地显示血管神经解剖关系,有助于提高阳性率的检出,利于术前明确病因及指导手术操作。Objective To investigate the value of the three-dimensional high-resolution magnetic resonance imaging curve planar reformation（CPR）combined with virtual endoscopy reconstruction in vascular compression of trigeminal neuralgia.Methods 65 pa-tients with trigeminal neuralgia performed three-dimensional MR doubly excited balanced steady-state free precession sequence （3D-FIESTA-C）,and CPR combined with virtual endoscopy reconstruction was used to evaluate the relationship of neurovascular anato-my.And 60 cases with microvascular decompression （MVD）surgery were analyzed.Results 65 cases of 3D-FIESTA-C CPR com-bined with MRVE showed responsibility vascular with a positive rate of 92.3% （60/65）.60 cases of all patients with the results of surgery showed responsibility blood vessels and oppression parts with 3D-FIESTA-C CPR combined with MRVE,and it was found that the findings of oppression had a good consistency with MVD with the diagnose accordance rate of 95% （57/60）.Conclusion Three-dimensional high-resolution magnetic resonance imaging CPR combined with virtual endoscopy reconstruction can be a new method to clearly and accurately show the anatomical relationship between blood vessels and nerves,which helps to improve the posi-tive rate of detection and to give operative guidance.
