目的：探讨磁共振三维稳态进动快速成像（three-dimensional fast imaging employing steady state acquisition ，3D-FI-ESTA）对原发性三叉神经痛的诊断价值。方法采用磁共振3D-FIESTA序列扫描52例原发性三叉神经痛患者的三叉神经出脑干段，并做多平面重建。分析患侧组及健侧组三叉神经出脑干段与邻近血管的关系。结果患侧组与健侧组神经血管接触阳性比例分别为52/53与35/51，神经受压推移比例分别为10/53与1/51，差异有统计学意义（ P＜0.05）。结论磁共振3D-FIESTA，可以清晰显示三叉神经与邻近血管的关系，为原发性三叉神经痛的诊断及治疗提供可靠的影像学依据。

Objective To evaluate the diagnostic value of MR three-dimensional fast imaging employing steady state acquisi-tion (3D-FIESTA) in patients with idiopathic trigeminal neuralgia .Methods The 3D-FIESTA and multi-plane reconstruction (MPR) were performed in 52 patients with idiopathic trigeminal neuralgia .MR images were analyzed to determine the relationship between the brain stem segment of trigeminal nerves and micro vessels of bilateral sides .Results Neurovascular contact could be found in 52/53 cases on the symptomatic sides and 35/51cases on the asymptomatic sides .Nerve compression or displacement was identified in 10 pa-tients on the symptomatic sides ,and 1 patient on asymptomatic sides .The differences between the neurovascular contact and nerve com-pression were significant (P<0.05).Conclusion MR 3D-FIESTA can clearly demonstrate the relationship between the nerve and surrounding blood vessels and provide credible imaging evidence for pathogenic diagnosis and clinical treatment planning .
