Abstract:
OBJECTIVES:To explore the value of three-dimensional fast gradient echo sequence (3D-GRE) in observation of the craniocervical junctional ligament.
METHODS:A total of 21 healthy volunteers underwent 3D-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 three-dimensional 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.
CONCLUSIONS:The 3D-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.
