MRI在前交叉韧带损伤诊断中的价值分析

Study on value of MRI in diagnosis of anterior cruciate ligament injury

目的分析磁共振(MRI)在前交叉韧带(ACL)损伤诊断中的价值。方法随机选取2015年5月至2017年5月该院收治的ACL损伤患者80例,所有患者均接受临床检查、MRI检查及关节镜检术,将金标准设定为关节镜检查结果,对临床检查与MRI检查在ACL损伤诊断中的价值进行分析。结果临床检查在ACL损伤诊断中的敏感度、特异度、准确度、阳性预测值、阴性预测值分别为56.9%(29/51)、86.2%(25/29)、67.5%(54/80)、87.9%(29/33)、53.2%(25/47);MRI检查在ACL损伤诊断中的敏感度、特异度、准确度、阳性预测值、阴性预测值分别为92.6%(50/54)、88.5%(23/26)、91.3%(73/80)、94.3%(50/53)、85.2%(23/27)。MRI检查在ACL损伤诊断中的敏感度、准确度、阳性预测值、阴性预测值均明显高于临床检查结果,差异有统计学意义(P<0.05)。结论 MRI在ACL损伤诊断中的敏感度及准确度均高于临床检查结果。

Objective To analyze the value of MRI in the diagnosis of anterior cruciate ligament（ACL）injury.Methods Eighty patients with ACL injury in this hospital from May 2015 to May 2017 were randomly selected and received clinical examination,MRI examination and arthroscopic surgery.The arthroscopic examination results were set as the gold standard.Then the values of clinical examination and MRI examination in the diagnosis of ACL injury were analyzed.Results The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of clinical examination in the diagnosis of ACL injury were 56.9%（29/51）,86.2%（25/29）,67.5%（54/80）,87.9%（29/33）and 53.2%（25/47）,which of MRI examination in the diagnosis of ACL injury were 92.6%（50/54）,88.5%（23/26）,91.3%（73/80）,94.3%（50/53）and85.2%（23/27 respectively）.The sensitivity,specificity and accuracy,positive predictive value and negative predictive value of MRI examination in the diagnosis of ACL injury were significantly higher than those of clinical examination,the difference was statistically significant（P〈0.05）.Conclusion The sensitivity and accuracy of MRI in the diagnosis of ACL injury are higher than those of clinical examination.
