摘要
目的分析采用多层螺旋CT的骨三维重建对肋骨及肋软骨损伤应用效果。方法收集2013年12月至2016年6月我院胸外伤患者51例为研究对象,采用多平面重建(MPR)、表面遮盖法(SSD)、曲面重建(CPR)、最大密度投影(MIP)进行三维重建,并与胸部平片进行对比,比较他们之间的特异度、灵敏度、阳性及阴性预测值,了解其诊断效果。结果51例胸部外伤患者中,肋骨骨折47例,肋软骨骨折2例,MPR灵敏度(88.5%)和特异度(93.6%)最高,阳性预测值为96.5%,阴性预测值为78.6%,要高于CPR、VR、SSD、MIP,差异具有统计学意义(P<0.05)。结论临床中应用多层螺旋CT检查肋骨及肋软骨损伤,可提供更准确、清晰的影像信息,对明确临床诊断及治疗具有良好的指导意义。
Objective Bone reconstruction of multislice spiral CT applications in the ribs and rib cartilage injury.Methods December 2013 to June 2016 in our hospital chest trauma 51 patients for the study,multi-planar reconstruction(MPR),shaded surface display(SSD),curved planar reconstruction(CPR),maximum intensity projection(MIP)three-dimensional reconstruction,and compared with chest radiography.Results 51 cases of patients with chest trauma,rib fractures in 47 cases,2 cases of costal cartilage fracture,MPR sensitivity(88.5%)and specificity(93.6%)the highest positive predictive value 96.5%,negative predictive value of 78.6%,to higher than CPR,VR,SSD,MIP,comparison was statistically significant(P<0.05).Conclusion The multilayer spiral CT ribs and cartilage damage,may provide a more accurate and clear image information of a clear clinical diagnosis and treatment has a good guide.
