目的探讨适合三叉神经-血管复合体虚拟解剖观察的MRI成像及重建方法.方法对6例三叉神经痛患者术前应用3D - FIESTA序列及3D-TOF序列进行扫描,所获得资料分别导入Dextroscope系统,对三叉神经血管复合体的各结构进行虚拟重建,比较两种序列的单独及融合重建效果.结果 6例资料均逼真重建出三叉神经及相关解剖结构.3D - FIESTA序列对神经及细小血管的重建优于3D-TOF序列,而3D-TOF序列对血流速度快的基底动脉及椎动脉的重建优于3D - FIESTA序列,两种序列融合重建效果更佳.结论应用MRI、3D-FIESTA及3D-TOF数据进行虚拟重建均可清晰显示三叉神经-血管复合体,二者融合重建可取长补短,效果更佳.

Objective To explore suitable magnetic resonance image sequence as the best method for image reconstruction of the virtual trigeminal neurovascular complex.Method 6 patients with trigeminal neuralgia were scanned preoperatively by 3D - FIESTA sequence and 3D - TOF sequences,and the image data were loaded into Dextroscope system to be extraceted,fused for reconstruction of trigeminal neurovascular complex.The virtual images were compared to what we had seen during the Micro - vascular Decompression.Results The virtual images in all 6 cases reflected the real relationship of the trigeminal nerve and its adjacent anatomical structure with high visualization.3D - FIESTA sequence played a better role in recreating small blood vessels,3D - TOF sequence was better for the basilar artery and vertebral artery reconstruction,respectively.The image had higher quality when combing the two sequences.Conclusions 3D - FIESTA MRI and 3D - TOF data both clearly show the anatomy relationship of the trigeminal neurovascular complex,but the two sequences should be combined to show more anatomical details and can make up the disadvantages of each other.
