摘　　要：目的:探讨64排螺旋CT三维重建在诊断隐匿性肋骨骨折中的应用价值。方法:选取2022年1月—2023年8月铜仁市第二人民医院收治的150例疑似隐匿性肋骨骨折患者作为研究对象,所有患者均行64排螺旋CT检查,并开展三维重建,以临床综合诊断为金标准,统计隐匿性肋骨骨折检出情况及诊断价值,并Kappa检验验证不同方法诊断隐匿性肋骨骨折与金标准的一致性。结果:150例疑似患者,经金标准确诊109例,其中64排螺旋CT三维重建确诊108例,阳性率为99.08%(108/109),常规CT平扫确诊104例,阳性率为95.41%(104/109);64排螺旋CT三维重建诊断隐匿性肋骨骨折的敏感度、特异度、准确度、阳性预测值、阴性预测值高于常规CT平扫,差异有统计学意义(P<0.05);Kappa检验显示,64排螺旋CT三维重建诊断与金标准的Kappa值为0.950,一致性高;常规CT平扫诊断与金标准的Kappa值为0.790,一致性高。结论:64排螺旋CT三维重建在隐匿性肋骨骨折中诊断价值高,可提高诊断准确性,便于早期发现隐匿性骨折,实现针对性治疗,更好地改善患者病情。Objective:To investigate the value of three-dimensional reconstruction of 64-row spiral CT in the diagnosis of occult rib fractures.Method:A total of 150 patients with suspected occulted rib fracture admitted to Tongren Second People's Hospital from January 2022 to August 2023 were selected.All patients underwent 64-slice spiral CT examination and three-dimensional reconstruction,clinical comprehensive diagnosis was used as the gold standard,the detection and diagnostic value of occulted rib fractures were counted,and Kappa test was used to verify different methods for diagnosing occulted rib fractures consistency with the gold standard.Result:In 150 suspected patients,109 cases were confirmed by the gold standard,of these,108 cases were confirmed by three-dimensional reconstruction of 64-row spiral CT,the positive rate was 99.08%(108/109),conventional CT plain confirmed 104 cases,the positive rate was 95.41%(104/109).The sensitivity,specificity,accuracy,positive predictive value,negative predictive value of three-dimensional reconstruction of 64-row spiral CT were higher than conventional CT plain,the differences were statistically significant(P<0.05).Kappa test showed that,CT three-dimensional reconstruction diagnosis and gold standard was 0.950,with high consistency.The Kappa value of conventional CT plain scan diagnosis and gold standard was 0.790,which was in high consistency.Conclusion:Three-dimensional reconstruction of 64-row spiral CT has high diagnostic value in concealed rib fracture,which can improve the accuracy of diagnosis,facilitate the early detection of concealed fracture,realize targeted treatment,and better improve the patient's condition.
