摘要
目的：应用MR 3D-FIESTA序列对动眼神经海绵窦段进行解剖显示与研究，为临床提供进一步MR影像解剖信息。方法：38例正常志愿者与8例动眼神经麻痹患者均行常规SE序列及3D-FIESTA序列扫描，利用多平面重组（MPR）和曲面重建（CR）技术从不同角度显示动眼神经海绵窦段的走行情况。结果：38例正常志愿者中40.8%（15例）可以清晰显示动眼神经海绵窦段，57.8%（22例）海绵窦段显示欠清晰，可显示部分动眼神经，1.3%（1例）海绵窦段未见显示。8例动眼神经麻痹患者，12.5%可清晰显示动眼神经海绵窦段，62.5%动眼神经部分显示，25%动眼神经未见显示。结论：MR 3D-FIESTA序列结合MR后处理技术能够在一定程度上提供动眼神经海绵窦段的解剖信息，对于病变累及海绵窦区显示情况较差，但是可提供间接解剖形态信息，为诊断及进一步的手术提供帮助。
Abstract
Objective: To asses the value of 3D-FIESTA sequence in displaying the cavernous sinus segment of oculomotor nerve in order to obtain more detailed MR anatomical data of this nerve for clinical application. Methods: Thirty-eight normal volunteers and 8 patients with oculomotor nerve palsy underwent conventional sequence and 3D-FIESTA sequence associated with multi-planar reformation(MPR) and curved planar reconstruction(CR) from different angle to show the pathway of the cavernous sinus segment of oculomotor nerve. Results: In the 38 normal volunteers, the cavernous segment of oculomotor nerve can be showed clearly in 40.8%(15 cases), can not be showed clearly in 57.8%(22 cases), only a part of the segment was showed, and the nerve can not be showed in 1.3%(1 case). In the 8 patients with oculomotor nerve palsy, the cavernous segment of the nerve can be showed clearly in 12.5%, only a part of the nerve can be showed in 62.5%, in 25% of cases the nerve was not showed. Conclusion: To some extent, MR 3D-FIESTA sequence with post-processing techniques can be used to show the anatomical detail of the canvernous sinus segment of the oculomotor nerve, but involvement of the cavernous sinus can not be showed clearly only provide indirect information for diagnosis and further surgery planning.
