摘　　要：目的:探讨磁共振的三维快速梯度回波序列(three-dimensional fast gradient echo sequence,3D-GRE)对颅颈交界区韧带结构的显示价值。方法:21例健康志愿者进行3D-GRE成像检测,将成像数据导入后处理工作站,应用多平面重建技术对颅颈交界区各韧带结构进行观察、评估。结果:21例健康志愿者的图像皆清晰显示颅颈交界区各韧带结构特点,扫描时间为267~294 s,经三维重建后可有效显示寰椎横韧带、翼状韧带、齿状尖韧带、覆膜的信号特点及走行结构。结论:3D-GRE能够在短时间内获取颅颈交界区韧带结构的三维数据,通过后处理重建技术能够清晰评价各韧带的结构特点,可为进一步应用于颅颈部外伤患者奠定基础。Objective: To explore the value of three-dimensional fast gradient echo sequence(3 DGRE) in observation of the craniocervical junctional ligament.Methods: A total of 21 healthy volunteers underwent 3 D-GRE imaging. The imaging data was imported into the post-processing workstation. The structures of the ligaments in the craniocervical junctional area were observed and evaluated by multiplanar reconstruction technique.Results: The features of ligaments in the craniocervical junction were shown clearly for all the 21 cases of volunteers. The scan time was 267-294 s. After the treatment with the threedimensional reconstruction technique, the signal characteristics and the running structure of the transverse ligament, the alar ligament, the serrated ligament and the lamina could be effectively displayed.Conclusion: The 3 D-GRE can evaluate the three-dimensional data of craniocervical junctional ligament in a short period of time. Post-processing reconstruction technique can clearly evaluate the structure characteristics of each ligament, which can lay a foundation for further application in craniocerebral trauma patients.
