目的：评价多排螺旋CT与CR在肋骨骨折诊断中的运用价值,探讨两种检查方法各自诊断肋骨骨折的优势,寻找提高诊断准确性的检查方法。方法回顾性分析2014~2015年60例因胸部外伤后来我院行影像学检查诊断有无肋骨骨折的患者。将患者随机分为CT检查组和CR检查组,每组30例。其中CT检查组：男19例,女11例；CR检查组：男17例,女13例。由放射科两名主治医师采用双盲法进行诊断。结果第1~3肋骨：CT诊断准确率为46.3%(25/54),CR诊断准确率为74.4%(32/43)；第4~8肋骨：CT诊断准确率为88.5%(119/135),CR诊断准确率为55.1%(81/147)；第9~12肋骨：CT诊断准确率为91.7%(55/60),CR诊断准确率为53.2%(33/62)。CT出现假阳性误诊率15.1%(71/471),CR出现假阳性误诊率7.1%(33/468)。结论多排螺旋CT与CR取长补短、配合检查能有效提高肋骨骨折诊断准确率,减少漏诊、误诊率。“,”Objective Evaluation of row Multi-slice Spiral CT and CR use value in the diagnosis of rib fracture, and to discuss the advantages of two different methods in the diagnosis of rib fracture, so look for ways to improve the accuracy of diagnosis. Methods Retrospective analysis of 60 patients who check rib fracture from 2014 to 2015 in our hospital because of chest trauma. The patients were randomly divided into CT inspection group and CR inspection group, and each group of 30 cases. Among them CT inspection group: male 19, female 11; CR inspection group: male 17, female 13. Two radiologists doctor diagnosis with double-blind method. Results 1 ~ 3 ribs: The diagnostic accuracy of CT was 46.3% (25/54), and the diagnostic accuracy of CR was 74.4% (32/43);4~8 ribs:The diagnostic accuracy of CT was 88.5% (119/135), and the diagnostic accuracy of CR was 55.1% (81/147); 9~12 ribs: The diagnostic accuracy of CT was 91.7% (55/60), and the diagnostic accuracy of CR was 53.2% (33/62). False positive misdiagnosis rate of CT was 15.1% (71/471), and false positive misdiagnosis rate of CR was 7.1% (33/468). Conclusion Multi-slice spiral CT and CR each other and cooperate with the inspection can effectively improve the accuracy of diagnosis of rib fracture, meanwhile reduce missed diagnosis and misdiagnosis rate.
