摘要
目的:研究距骨骨折螺旋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:收集距骨骨折患者术前螺旋CT资料12例,同时进行了MPR和3D重建图像。着重分析距骨骨折线的走行、与关节面的关系、关节面塌陷程度等,并评价轴扫、MPR和3D重建图像的优势。结果:在12例距骨骨折者骨踝关节受累7例。MPR和3D重建图像可直观显示骨折详细情况。结论:螺旋CT轴扫、多平面和三维重建图像相结合,可更好显示距骨骨折的情况,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 features and clinical significance of Spiral CT axis, multiplanar reformation （MPR） and three Dimension （3D） reconstruction images in talus fractures. Methods： Twelve cases with talus fractures underwent spiral CT, and the images were reformed with 3D reconstruction and MPR that focused on the following aspects： the fracture line, the situation of joint surface, the collapse of involved joint surface, and the results were compared with each other. Results： The 7 cases of ankle joint were found in 12 cases of talus fractures. MPR and 3D images showed the characteristics of fracture clearly. Conclusion： Spiral CT axial images combinated with MPR and 3D images can provide more valuable information of the clinical diagnosis and therapy for talus fracture.
