MPR及3D成像在骨关节外伤诊断中的临床应用

目的 :探讨多平面重建及三维CT成像在骨关节外伤诊断中的价值。方法 :分析 5 0例骨关节外伤病例 ,均进行多平面重建 (MPR)和三维 ( 3D)重建 ,并与轴位成像 ( 2DCT)进行比较。结果 :MPR和 3D重建图像能很好地显示骨折线、骨折片移位及关节脱位 ,3D重建可立体显示骨折的空间关系。结论 :MPR和 3D图像是轴位图像的重要补充 ,为骨关节外伤的术前分型、治疗方法的选择及手术入路提供了客观依据 ,具有很高的临床应用价值。

Application of MPR and 3D imaging with helical CT in diagnosis of osteoarticular injury

Objective:To evaluate MPR and 3D imaging with helical CT in diagnosis of osteoarticular injury.Methods: MPR and 3D imaging in 50 cases of osteoarticular injury were compared with axial 2D imaging of CT.Results:MPR and 3D imaging could show the fracture line and displacement of fractured osseous fragments and dislocation of joint clearly.3D images can display anatomy and spatial relationship of structures.Conclusion:MPR and 3D imaging are important supplement to axial 2D images and can provide more accurate preoperative classification of fractures and appropiate planning for surgical treatment of osteoarticular injury.
