磁共振技术诊断膝关节损伤的临床价值

Clinical value of magnetic resonance imaging in diagnosis of knee injuries

目的:探讨磁共振在膝关节损伤患者临床诊断中的应用价值。方法:收治膝关节损伤患者61例,采用磁共振检查,与膝关节镜的诊断结果进行比较。结果:磁共振技术诊断膝关节损伤的准确性83.60%(51/61)、敏感性90.69%(39/43)、特异性66.67%(12/18)、假阳性率33.3%(6/18)、假阴性率9.30%(4/43)。结论:磁共振技术在膝关节损伤患者的临床诊断中,准确、灵敏,且快速、无创、经济、方便。

Objective:To explore the clinical value of magnetic resonance imaging in diagnosis of knee injuries.Methods:61patients with knee injuries were selected,and they were given magnetic resonance imaging,and the results were compared with the knee arthroscopy.Results:Accuracy of magnetic resonance imaging in diagnosis of knee injuries was 83.60%(51/61),sensitivity was 90.69%(39/43),specificity was 66.67%(12/18),false positive rate was 33.3%(6/18),false negative rate was 9.30%(4/43).Conclusion:Magnetic resonance imaging in diagnosis of knee injuries had many advantages,such as accurate,sensitive,fast,noninvasive,economical and convenient and so on.
