螺旋CT重建技术在骨关节骨折中的应用价值

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

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例肩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。

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.
