摘　　要：目的分析容积再现成像技术在肋骨骨折诊断中的价值。方法选择2015年3月至2017年12月行64排螺旋CT检查的肋骨骨折患者100例,行薄层CT扫描,记录3种后处理技术曲面重建(CPR)、多层面重建(MPR)及容积再现(VR)成像技术诊断肋骨骨折数目及位置,并对比三者的敏感性及特异性。结果100例患者,CPR成像技术敏感性为91.64%,特异性为99.66%;MPR成像技术敏感性为90.24%,特异性为99.71%;VR成像技术敏感性为87.00%,特异性为99.83%。结论VR成像技术特异性在三者中最高,敏感性较低,可用于肋骨骨折筛查。Objective To evaluate the application value of volume rendering technique in diagnosis of rib fracture.Methods A total of 100 patients with rib fracture who underwent 64-slice spiral CT examination in our hospital from March2017 to December 2017 were enrolled in the study,At first,these patients were examined by thin-slice CT scan,then the number and location of rib fractures diagnosed by the three kinds of postprocessing techniques including multiplanar reconstruction(MPR),curved surface reconstruction(CPR) and volume rendering technique(VRT) was recorded,and the sensitivity and specificity of the three kinds of examination methods were observed and compared.Results The detection rate of rib fracture by CPR was significantly higher than that by VRT,which by MPR was significantly higher than that by VRT(P<0.05).Moreover the sensitivity and specificity of CPR were 91.64%,99.66%,respectively,which by MPR were90.24%,99.71%,respectively,which by VRT were 87.00%,99.83%,respectively.Conclusion The specificity of VRT is the highest among the three kinds of examination methods in diagnosis of rib fracture,however,its sensitivity is lower,which can be used in screening of rib fracture.
