Objective To study the image features and clinical significance of 3D and multiplanar reconstruction helical CT in cervical spinal fractures. Methods 20 cases of cervical spinal fractures underwent spiral CT scanning and were observed with axial scanning, 3D and multiplanar reconstruction (MPR) image that focused on the cervical spinal fracture and characteristics of CT manifestation. Results In the 20 cases, axial CT demonstrated 25 vertebral body fractures, 5 spinous process fractures, 5 pedicles fractures, 10 laminal fractures, 1 articular dislocations, 2 vertebral dislocation, 1 rotation, and 22 spinal canal stenosis. 3D surface reconstruction demonstrated 25 vertebral body fractures, 5 spinous process fractures, 4 pedicles fractures, 7 laminal fractures, 3 articular dislocations, 2 vertebral dislocation, 1 rotation, and 22 spinal canal stenosis. 3D and MPR demonstrated vertebral body fracture well, but for dislocation and/or rotation, 3D surface reconstruction was better. Conclusion 3D and MPR of spinal CT are useful in the diagnosis of cervical spinal fractures. The combination of axial helical CT scanning, 3D, and MPR will greatly contribute to establish a correct preoperative diagnosis and accordingly to select a right surgical approach.

目的探讨颈椎骨折螺旋CT轴扫、多平面(MPR)和三维(3D)重建图像的特点及其临床意义。方法收集颈椎骨折患者术前螺旋CT资料20例,同时进行了MPR和3D重建图像分析。着重观察颈椎骨折的部位、椎体序列、椎体高度、骨折线、椎体附件骨折和旋转/脱位等的螺旋CT表现,并评价轴扫、MPR和3D重建图像的优势。结果在20例中,轴位螺旋CT显示25个椎体骨折,5个棘突骨折,5个椎弓根骨折,10个椎板骨折,1个寰枢椎脱位,2个椎小关节脱位,1个椎体旋转,0个非寰枢椎椎体脱位,22个椎管狭窄。MPR图像显示上述结构异常分别为:25,5,4,8,3,2,1,2,22。3D图像显示上述结构异常分别为:25,5,4,7,3,2,1,2,22。3D和MPR显示椎体骨折效果好,但对附件显示欠佳;在显示椎体脱位和旋转方面,3D重建最直观。结论颈椎骨折的螺旋CT、3D和MPR重建,是轴位CT扫描有价值的补充,可更好显示骨折的情况,能为临床术前诊断和治疗提供有价值的影像信息。

Objective To study the image features and clinical significance of 3-dimensional (3-D)and multiplanar reconstruction with spiral CT(SCT) in cervical spinal fractures.MethodPlain film radiography and spiral CT scanning were taken for 26 cases of cervical spinal fractures.The type of fractures, diagnositic successful rate, parameter of scanning and late stage managing methods were investigated retrospectively to find out the effective difference between the diagnosis of plain X-ray and SCT. The imagin location of fractures,sequence of cenrum, heighth of centrum, fracture line, auxillary structure and rotation/dislocation of the fractures were emphasized to evaluate the advantages of 3-D imaging.ResultIn the 26 cases, there were 4 Jefferson fractures, (in which 1 combined with articular dislocations), 17 C2 spinous process fractures, (in which 1 had failure of plain X-ray diagnostic), 1 Hangman fracture, 2 C1~2 imbalance, (in which 1 had failure of plain X-ray diagnostic).There were 2 cases of axoid longitudinal fractures without obvious dislocation. The diagnositic successful rate were 100% in SCT group, while 65% in X-ray group in which 6 cases had diagnostic failure and 3 cases had fracture mis-diagnozing as dislocation.The anatomical structure of upper cervical spine was complicated and was significantly different from other cervical spine constructions. Spiral CT could reveal high resolution images of the upper cervical spine, morphosis of vertibral canal, dislocation information of fracture mass and its relation with neighbouring tissues. Especially in C1 burst fracture,C2 dens fracture and C1~2 dislocation, SCT could provide clear 3-D information of the size of collateral mass and the dislocation degree, furthermore, images could be rotated freely to observe the fracture in any proper section. That provides important information for the decision of operation, selection of operation types and evaluation of operation dager.ConclusionThe spiral CT scan and 3D reconstruction can reveal fracture better.The advantages of SCT are suggested that this diagnostic modality may be the standard method for the initial evaluation of the upper cervical spine injury.
