摘 要: | 目的研究磁共振成像(MRI)在前交叉韧带损伤辅助诊断中的应用。方法选取我院2011年9月至2013年9月前交叉韧带损伤患者78例,对患者先进行临床检查和MRI检查,然后进行关节镜手术检查。以关节镜检查的结果为金标准,比较临床检查和MRI检查两种方式对前交叉韧带损伤的诊断情况、准确度、敏感度和特异度。结果临床检查前交叉韧带的真阳性率为38.46%较MRI检查66.67%显著较低(P0.05);临床检查前交叉韧带的假阴性率为21.79%较MRI检查2.56%显著较高(P0.05);MRI检查的准确度为94.87%、敏感度为66.67%较临床检查70.51%、38.46%显著较高(P0.05)。结论 MRI检查是一种无创、无放射性、准确性较高的诊断方法,其检查结果能为关节镜检查和前交叉韧带重建提供重要依据,在交叉韧带损伤的诊断方面有一定的临床价值,应予以应用推广。

Abstract: | Objective To study application of magnetic resonance imaging (MRI) in auxiliary diagnosis of anterior cruciate ligament injury.Methods 78 cases of anterior cruciate ligament injury treated in our hospital from September 2011 to September 2013 were selected, all patients underwent clinical examination and MRI examination, then underwent arthroscope operations research examination. Arthroscope operations research examination results were served as the gold standard, diagnosis of anterior cruciate ligament injury, accuracy, sensitivity and specificity by clinical examination and MRI examination were compared.Results True positive rate of clinical examination anterior cruciate ligament was 38.46%, which was significantly lower than MRI examination (66.67%) (P<0.05); false negative rate of clinical examination anterior cruciate ligament was 21.79%, which was significantly higher than MRI examination (2.56%) (P<0.05); accuracy of MRI examination was 94.87%, sensitivity was 66.67%, which were significantly higher than clinical examination (70.51%, 38.46%) (P<0.05).Conclusion MRI examination is a non-invasive, non radioactive diagnostic method with a higher accuracy, its inspection result can provide an important basis for arthroscopic examination and anterior cruciate ligament reconstruction, it has some clinical value in the diagnosis of cruciate ligament injury, should be applied and popularized. |
