摘　　要：目的探讨三维时间飞跃法磁共振血管成像结合三维重建技术在血管压迫性三叉神经痛诊治中的价值。方法选择我院2012年1月至2014年2月收治的80例血管压迫性三叉神经痛患者作为研究对象,对其进行轴位MRI 3D-TOF检查,同时结合解剖教研室3D血管和神经重建成像系统,将血管和神经的位置关系进行重建,进一步诊治。结果根据三叉神经与周围血管压迫分型进行诊断,医师1的诊断结果为Ⅰ型29例,Ⅱ型19例,Ⅲ型32例,医师2的诊断结果为Ⅰ型48例,Ⅱ型21例,Ⅲ型11例,两位医师的诊断结果比较差异有统计学意义(P=0.00);通过与术中诊断比较,参考三维重建的诊断结果更符合术中诊断,即结合三维重建技术的诊断结果与术中诊断结果比较差异无统计学意义(P=0.98)。结论 MRI 3D-TOF结合三维重建技术在血管源性三叉神经痛的诊断中,对神经与其周围血管之间关系的显示较为理想,可以用于血管源性三叉神经痛的诊断。Objective To explore the value of 3D time-of-flight MRI（ MRI 3D-TOF） combined with 3D reconstruction technique for the diagnosis and treatment of vascular compression of trigeminal neuralgia by magnetic resonance angiography combined with three-dimensional reconstruction technique. Methods A total of 80 patients with vascular compression of the trigeminal neuralgia in our hospital from January 2012 to February 2014 were diagnosed by axial MRI 3D-TOF,combined with 3D vascular and nerve reconstruction in the anatomy Department for further diagnosis and treatment. Results The patients were diagnosed according to the trigeminal nerve and the typings of peripheral vascular compression. The diagnosis results for 29 cases of type Ⅰ,19 cases of type Ⅱ,32 cases of type Ⅲ from physician 1,the diagnosis results for 48 cases of type Ⅰ,21 cases of type Ⅱ and type Ⅲ in 11 cases from physician 2,the difference of the diagnosis bwtween two physicians was statistical significance（ P = 0. 00）. Compared with intraoperative diagnosis,the diagnosis of 3D reconstruction results was similar to the intraoperative diagnosis,and the difference was no statistical significance（ P = 0. 98）. Conclusion MRI 3D-TOF combined with three-dimensional reconstruction technique in the diagnosis of vascular trigeminal neuralgia shows clear images of the nerve and its surrounding vessels,which can be applied to the diagnosis of trigeminal neuralgia.
