螺旋CT多平面和三维重建在肘关节骨折中的诊断价值

目的探讨螺旋CT多平面重建(MPR)和三维重建(3D)在肘关节骨折诊断中的价值。方法对24例肘关节损伤患者行多层螺旋CT扫描并进行多平面和三维重建。结果24例中检出22例42处骨折,4例关节脱位。轴位平扫CT(2D CT)发现29处骨折,MPR显示骨折39处,3D发现骨折35处。结论MPR在发现小的骨折方面及显示骨折内部情况较好,而3D能直观、立体、多角度地显示肘关节的损伤。MPR和3D在诊断肘关节骨折中有重要价值。

Clinical Value of Multiplanar Reconstruction and Three Dimensional Reconstruction with Spiral CT in the Fractures of the Elbow Joint

Objective To evaluate the clinical applied value of multiplanar reconstruction(MPR) and three dimensional reconstruction(3D) with spiral CT in the fractures of the elbow joint.Methods Multi-slice helical CT scanning was performed in 24 cases with elbow joint injure,MPR and 3D image reconstruction of elbow joints were carried out.Results 42 fractures and 4 dislocations of elbow joints in 22 cases were found on the images of MPR and 3D,29 fractures were displayed on 2D CT,39 fractures were found on MPR and 35 fractures were viewed on 3D.Conclusion MPR is better than 3D in finding the small fractures and in viewing damage inside the bone of elbow joint,however 3D is better than MPR in showing the location,range,shift of fractures.MPR and 3D with spiral CT have important values in diagnosis of elbow joint fractures.
