摘　　要：目的 研究CT三维重建在隐匿性肋骨骨折(ORF)患者诊断中的应用。方法 选择2021年5月至2023年5月在我院治疗的75例(133处)ORF患者。所有患者均进行数字化X线摄影(DR)、多层螺旋CT(MSCT)检查。比较DR与MSCT对ORF检出率,比较MSCT中不同重建技术对ORF检出率。结果 MSCT对ORF检出率高于DR,差异有统计学意义(P <0.05);容积再现(VR)、多平面重建(MPR)、曲面重建(CPR)对ORF检出率高于最大密度投影(MIP),MPR、CRP对ORF检出率高于VR,差异有统计学意义(P <0.05);MPR、CRP对ORF检出率比较,差异无统计学意义(P> 0.05)。结论 与DR相比,MSCT对ORF检出率更高,CT三维重建中MPR、CRP能够为ORF诊断获取更多的信息,有利于提高ORF检出率。Objective To study the application of CT three-dimensional reconstruction in the diagnosis of occult rib fracture(ORF)patients.Methods 75 patients(133 locations)with ORF who were treated in our hospital from May 2021 to May 2023 were selected.All patients underwent digital radiography(DR)and multi-slice spiral CT(MSCT)examination.Compare the detection rate of ORF between DR and MSCT,and compare the detection rate of ORF using different reconstruction techniques in MSCT.Results The detection rate of ORF in MSCT was higher than that in DR,and the difference was statistically significant(P<0.05).The ORF detection rate of volume reconstruction(VR),multiplane reconstruction(MPR)and surface reconstruction(CPR)was higher than that of maximum density projection(MIP),and the ORF detection rate of MPR and CRP was higher than that of VR,the difference was statistically significant(P<0.05).There was no significant difference between MPR and CRP in the detection rate of ORF(P>0.05).Conclusions Compared with DR,MSCT has a higher detection rate for ORF,and MPR and CRP in CT three-dimensional reconstruction can obtain more information for ORF diagnosis,which is beneficial for improving the detection rate of ORF.
