The diagnostic value of magnetic resonance imaging in minor rib fracture
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.
