磁共振3D FIESTA-C联合3D-TOF序列对血管压迫性面肌痉挛的诊断价值

The study of diagnostic value of MR 3D FIESTA-C combined with 3D-TOF sequence in angio-compressive facial spasm

目的探讨磁共振3D FIESTA-C联合3D-TOF序列对血管压迫性面肌痉挛的诊断价值。方法分析32例面肌痉挛患者的磁共振3D FIESTA-C及3D-TOF序列图像,观察症状侧及非症状侧的面神经与周围血管的关系。结果 32例症状侧面神经与周围血管表现为接触阳性共26侧,非症状侧表现为接触阳性7侧。两组间差异有统计学意义(P<0.05)。结论 3D FIESTA-C联合3D-TOF序列可清晰显示面神经与周围血管的关系,对血管压迫性面肌痉挛具有很高的诊断价值,以指导临床治疗。

Objective To evaluate the value of 3D FIESTA-C combined with 3D-TOF sequence in diagnosis of neurovascular compression in angio-compressive facial spasm. Methods The images of 3D FIESTA-C and 3D-TOF sequence were analyzed in 32 hemifacial spasm patients. And the relationship between facial nerve and adjacent vessels were judged and compared with clini- cal symptoms. Results 26 sides showed vascular compression or contact at 3D FIESTA-C and 3D-TOF images in 32 symptomatic sides. And 7 sides had vascular compression or contact relationship in the 32 healthy sides. There was statistically significant difference between the symptomatic and heathy side （ P 〈 0.05 ）. Conclusion 3D FIESTA-C combined with 3D-TOF sequence can clearly show the relationship between the facial nerve and surrounding blood vessels, and it is of important value in diagnosing angio-compressive facial spasm to guide clinical treatment.
