螺旋CT三维重建在骨盆骨折中的临床应用

目的探讨螺旋CT三维重建在骨盆骨折中的临床应用价值。方法回顾性分析1999~2004年43例骨盆骨折病例,凡手术治疗者手术前均行X射线摄片,再行螺旋CT三维重建并与手术对照。结果所有病例螺旋CT三维重建明确地显示了骨折,螺旋CT三维重建在骨折的分型和碎骨的描述上较平片优越,与手术中所见一致。结论螺旋CT三维重建能够更精确地显示骨盆骨折的情况,在骨盆骨折诊断和分型中具有重要的作用,对治疗方法的选择具有指导意义。

Spiral CT with 3 D reconstruction for pelvic fracture

Objective To investigate the clinical value of spiral CT with 3D reconstruction in the pelvic fractures. Methods 43 cases of pelvic fractures examined with spiral CT in our hospital from 1999 to 2004 were studied retrospectively. All patients treated surgically were given the pelvic X-ray photography and then spiral CT with 3D reconstruction preoperatively. The results were compared with the findings in operation. The scanning parameters of spiral CT were: collimation: 2-5 mm, table speed: 3-5 mm, and reconstruction interval: 1.5-3 mm. Results All fractures were demonstrated definitely with spiral CT in all cases. Analysis of the results showed the spiral CT with 3D reconstruction superior to plain X-ray films in the classification of the fractures, and the exact assessment of the quantity of fragments, which were coincident with the findings in operation. Conclusion Spiral CT with 3D reconstructions gives us a better and more accurate demonstration of pelvic fractures. It is an effective method in classifying and diagnosing pelvic fractures. It may therefore be helpful to establishment of a more precise therapeutic plan for these patients.
