【摘要】 目的 :探讨多层螺旋CT扫描检查对肋骨骨折的诊断价值。方法 :65例肋骨骨折患者行X线及多层螺旋CT扫描检查 ,观察和分析骨折的位置、数量及周边的其他病变。结果 :65例中 ,CT检查共发现肋骨骨折 12 1处 ,肋软骨骨折 5处。冠状位及矢状位重组图像清晰地显示出骨折线的数目及断端移位情况。结合 4D重组图像 ,肋骨骨折线的显示更直观、明了。X线检查共发现肋骨骨折 117处 ,肋软骨骨折 0处。结论 :多层螺旋CT轴位图像、MPR及 4D重组图像的联合应用 ,对判断肋骨骨折有很高的诊断价值 ,优于常规X线检查。更多还原

【Abstract】 Objective:To evaluate the multi-slice helical CT (MSCT) in the diagnosis of rib fracture.Methods:Sixty-five patients with rib fracture were examined with MSCT and conventional X-ray examination.The location,number and circumjacent pathological changes were observed and analyzed.Results:In all of sixty-five patients with rib fractures,there were 121 rib fractures and 5 costal cartilage fractures depicted on MSCT.Coronary and sagittal reconstruction images could show clearly the fracture line,number of fracture and displacement.Combining 4D reconstruction images,the fracture line could be shown more clearly.X-ray examination could detect 117 rib fractures but no costal cartilage fracture.Conclusion:MSCT axial images combining MPR and 4D reconstruction is a very useful examination method in the diagnosis of rib fracture,it excels the routine X-ray examination.更多还原
