螺旋CT重建技术在骨关节骨折中的应用价值

目的：探讨螺旋CT二维及三维重建技术在骨关节骨折中的应用价值。方法：收集2004年6月～2005年6月我院骨外伤患者，共15例，男12例，女3例，年龄：23。55岁。平均32岁。肋骨8例，肩关节3例，骨盆1例，踝关节2例，肘关节1例。采用螺旋CT后处理技术：MPR、MIP、SSD对所有患者临床可疑骨折部位进行重建，获取直观、清晰的重建图像。结果：8例X线平片肋骨可疑骨折经CT重建后，肯定了原来X线平片“可疑骨折”的有6例；否定了原来X线平片“可疑骨折”的有2例。3例扁关节经过重建后均发现了X线平片未显示的多处骨折及骨折线是否累及关节面的情况。骨盆1例较好地显示了髋臼骨折后的关节面情况。踝关节2例显示了X线平片未能显示的腓骨远端的细小骨折情况。1例肘关节显示了尺骨鹰嘴撕脱骨片的游走情况。结论：螺旋CT重建技术在骨关节骨折中具有很大的应用价值。

Clinical value of spiral CT reconstruction technique in fracture of bone and joint

Obiective:To evaluate the value of reconstruction of spiral CT in the diagnosis of fracture of bone and joint. Methods:Fifteen patients with suspectable fracture were performed by thin-slice volume scan of spiral CT. Malti-planer reconstruction (MPR),maximum intensity reconstruction(MIP),surface shaded display(SSD) were applied and the results of different methods of reconstruction were analyzed. Results:All of the 15 patients got correct diagnosis;8 cases of joint fracture were shown more tiny small fracture and detailed structure. Conclusion:Spiral CT reconstruction techniques such as MPR,MIP,SSD play an important role in showing all sorts of fracture. They are help for the clinical management planning.
