矢状位重建在脊柱常见病变中的应用

Use of CT multiplanar reconstruction in diagnosis of frequent spinal diseases

目的探讨矢壮位多平面重建在诊断脊柱常见病变中的应用方案与价值。方法选取脊柱常见病人60例,经CT轴位平扫后对原始数据进行矢壮位多平面重建(MPR),并与常规轴位图像(2DCT)进行比较。结果全部病例中共检出椎间盘突出42例,椎体及附件骨折16例,椎体肿瘤2例。结论矢壮位多平面重建对脊柱常见病变的CT评价可以延伸到直观、立体地观察椎体及附件、椎间盘、脊髓病变的形态学表现,以及病变部位与周围结构的情况,对制定合理的治疗方案及预后的判断有一定的指导意义。

Objective To describe the program of multiplanar reconstruction of CT images (MPR) and to discuss its usefulness in diagnosing frequent spinl diseases.Methods Sixty patients with frequent spinal deseases were collected and studied by sagittal multiplanar computed tomographic scanning(CT/MPR).Sagittal MPR of the original data was performed after axial plain scans and compared with conventional axial images (2D CT).Results The study demonstrated that there were 42 cases of intervertebral disk protrusions, 16 cases of vertebral body and its appendage fractures,and 2 cases of vertebral body tumors in all patients.Conclusion The program of sagittal MPR is especially useful in the evaluation of frequent spinal diseases. MPR can not only directly and stereoscopically reveal the morphologic appearances of vertebral body,appendage,interverteabral disc,and myelopathy but can reveal the relationship between the lesion and its peripheral structures so that it plays an important role in planning the reasonable treatment plan and predicting the prognosis.
