【摘要】：目的:总结MSCT在肋骨骨折诊断不当的原因,提高MSCT检查肋骨骨折的检出率和正确率。方法:回顾性分析我院173例肋骨骨折患者的资料。首次MSCT在骨折后1周内进行,并于创伤2周后复查。以Wilcoxon配对符号秩和检验说明两次(首次及复查诊断)诊断结果存在差异。由2名放射科高年资医师在已知复查骨折数目的前提下,分析首次MSCT骨折数目不同的原因。对其原因分三类,即漏诊、误诊及假阴性。结果:173例病患者中,首次MSCT共检出肋骨骨折552处,复查MSCT共检出肋骨骨折729处。两次诊断结果差异有统计学意义(Z值=7.881,P0.01)。复查MSCT诊断比首次多了213处,其中漏诊83处,占38.96%,误诊18处,占8.45%,假阴性112处,占52.58%。结论:MSCT诊断肋骨骨折存在一定的局限性,应仔细对图像进行综合分析,并加强随访复查。
[Abstract]:Objective: to summarize the causes of improper diagnosis of rib fracture by MSCT and to improve the detection rate and correct rate of rib fracture by MSCT. Methods: the data of 173 cases of rib fracture in our hospital were analyzed retrospectively. MSCT was performed within 1 week after fracture for the first time. After 2 weeks of trauma, the results of two diagnoses (first and second diagnosis) were proved to be different by Wilcoxon pair sign rank sum test. The causes of the different number of first MSCT fractures were analyzed. The causes were divided into three categories: missed diagnosis, misdiagnosis and false negative. Results 552 rib fractures were detected by MSCT in the first time. A total of 729 rib fractures were detected by MSCT. The difference between the two diagnostic results was statistically significant. There were 213 more MSCT diagnoses than for the first time, 83 missed diagnosis (38.96%), 18 misdiagnoses (8.45%) and 112 false negative cases (P < 0.05). Conclusion MSCT has some limitations in the diagnosis of rib fracture, so we should make a comprehensive analysis of the images carefully and strengthen the follow-up and reexamination.
