摘　　要：目的 探究磁共振成像(MRI)对细微肋骨骨折的诊断价值。方法 选取64例疑似细微肋骨骨折患者,均接受常规CT、MRI检查。以手术结果作为诊断金标准,分析两种方法的诊断结果;比较两种方法的诊断效能、对骨折类型的检出情况及诊断满意度。结果 以手术结果作为金标准,结果显示,阳性60例、阴性4例;常规CT检出阳性50例,阴性14例;MRI检出阳性59例,阴性5例。MRI的诊断敏感度96.7%和准确度95.3%均高于常规CT的80.0%、78.1%,差异有统计学意义(P<0.05);两种方法的诊断特异度比较差异无统计学意义(P>0.05)。MRI对Ⅰ型、Ⅱ型骨折的检出率分别为94.7%、90.9%,均高于常规CT的76.3%、63.6%,差异有统计学意义(P<0.05)。MRI的诊断满意率93.8%高于常规CT的73.4%,差异有统计学意义(P<0.05)。结论 应用MRI可以显著提高细微肋骨骨折的诊断准确度,普遍得到患者及其家属的认可,大幅度提升临床诊断满意度,诊断效果显著。Objective To explore the diagnostic value of magnetic resonance imaging(MRI) in minor rib fracture.Methods 64 patients with suspected micro rib fracture were selected.All of them received routine CT and MRI examination.The diagnostic results of the two methods were analyzed using surgical findings as the gold standard;the diagnostic efficacy,detection of fracture types,and diagnostic satisfaction of the two methods were compared.Results Using the surgical results as the gold standard,the results showed 60 positive cases and 4 negative cases;routine CT detected 50 positive cases and 14 negative cases;MRI detected 59 positive cases and 5 negative cases.The diagnostic sensitivity of 96.7% and accuracy of 95.3% of MRI were higher than those of 80.0% and 78.1% of routine CT,and the difference was statistically significant(P<0.05).The difference in diagnostic specificity between the two methods was not statistically significant(P>0.05).The detection rates of MRI for type Ⅰ and type Ⅱ fractures were 94.7% and 90.9%,which were higher than 76.3% and 63.6% of routine CT,and the difference was statistically significant(P<0.05).The diagnostic satisfaction rate of MRI was 93.8%,which was higher than 73.4% of routine CT,and the difference was statistically significant(P<0.05).Conclusion The application of MRI can greatly improve the diagnostic accuracy of micro rib fractures,which is generally recognized by patients and their families,and greatly improve the satisfaction of clinical diagnosis with remarkable diagnostic effects.
