128层螺旋CT的MPR和VR在胫骨平台骨折中的应用

Clinical application of MPR and 3D reconstruction with MSCT in tibial plateau fractures

目的:探讨螺旋CT MPR和三维重建(3D-CT)技术在胫骨平台骨折中的临床应用。方法:回顾性分析经128层螺旋CT的MPR和3D技术证实的60例胫骨平台骨折病例。结果:所有胫骨平台骨折经3D及MPR成像后均能立体显示骨折的部位、形态、类型、关节面碎裂及塌陷程度等空间信息,较平片优越,与手术中所见一致。结论:螺旋CT的MPR及3D技术能够更精确地显示胫骨平台的骨折情况,对骨折的分型判断及治疗方法的选择具有指导意义。

Objective：To study the diagnostic and clinical application value of multiplane reconstruction technology and 3 dimensional（3D） reconstruction by 128 slice spiral CT.Methods：60 patients with tibial plateau fractures who were imaged by MPR and 3D reconstruction were performed.Results：The positions,shapes,types and articular surface＇s spatial infor-mation of every fractures were shown clearly on MPR and 3D reconstruction images.Conclusion：MPR and 3D reconstruction by 128 slice spiral CT contribute to the precise diagnosis and classification of tibial plateau fracture,and is of importance to the selection of proper therapy.
