目的 探讨多层螺旋CT重建在肋 骨骨折中的应用价值分析。方法 用西门 子Sensation 16层螺旋CT机按照胸部常规 扫描条件对56例胸部外伤患者进行扫描， 运用重建技术显示肋骨骨折的部位、数 量，并与X胸片检测结果进行对比。结果 56例患者确诊共有肋骨骨折231处，X胸片 确诊肋骨骨折147处(占63.6％)， CT重建 确诊212处(占91.7％)，CT薄层结合三维 重建确诊231处(占100.0％)。结论 多层 螺旋CT扫描结果在进行三维重建，可以在 图像上清晰显示肋软骨折及骨折线，为骨 折提供了一个新的检查方法，有较高的临 床应用价值。

Objective To discuss the application of multi-slice CT reconstruction in fractured ribs value analysis. Methods With Siemens since 16 layers spiral CT machine according to the chest routine scan conditions on 56 patients with chest trauma were scanned, using reconstruction technology display number and positions of fractured ribs, and compared with testing results of X-ray chest radiography. Results 56 patients were confirmed a total of 231 of fractured ribs, X-ray chest X-ray diagnosis of rib fracture, 147 (63.6%), CT reconstruction confirmed that 212 (91.7%), thin layer combined with 3 d reconstruction CT diagnosis of 231 (100.0%). Conclusion Multi-slice CT scan findings in 3 d reconstruction, can clear display on image soft rib fractures and fracture line, broken bones, provides a new examination method, has high clinical value.
