摘要
目的:使用SE-EPI序列行颈髓纤维跟踪成像,探讨健康人及某些病变中颈髓纤维跟踪成像的表现。方法:研究包括22名健康志愿者,6名脊髓空洞症患者,3名颈髓肿瘤患者。使用SE-EPI序列行颈髓DTI成像,应用fibertracking软件行纤维跟踪成像。将多个图像融合,得到整个颈髓的纤维束图。结果:所有健康人均可得到与颈髓解剖结构基本一致的白质纤维束图;脊髓空洞患者的纤维跟踪图均可清晰地显示颈髓中央空洞的形态;颈髓肿瘤也可以用DTI的纤维束追踪技术直观的显示出其纤维束受累情况。结论:颈髓纤维跟踪成像技术为临床提供了显示颈髓病变更直观的信息,可以为外科手术与治疗提供参考。
Objective：To investigate the feasibility of tractography of the cervical spinal cord by SE-EPI sequence to show fibers of normal volunteers and patients with some diseases of the cervical spinal cord.Methods：22 normal volunteers,6 patients with syringomyelia and 3 patients with spinal cord tumors received DTI examination by SE-EPI sequence.Get the tractography by using fiber tracking software.Results：Tractography of the white matter of normal volunteers were obtained and were accordance to the anatomy of the cervical spinal cord.Tractography of syringomyelia patients demonstrated hollow of the cord.Tumors could also be delineated macroscopically.Conclusion：Tractography of the cervical spinal cord applies macroscopic information and is helpful to surgery and treatment of disorders.
