摘　　要：目的探讨CT检查和磁共振成像对膝关节骨折周围韧带和肌腱损伤的鉴别诊断价值。方法选取80例膝关节骨折伴随周围韧带和肌腱损伤的患者作为研究对象。将患者按照检查类型进行分组:CT检查组、MRI检查组、联合检查组,对比分析单一检查应用的特异度、敏感度、准确度。结果①入组疑似病例经“金标准”检查确诊48例,确诊率为60.0%,CT检查阳性患者35例,MRI检查阳性患者40例,联合检查阳性患者46例;②在本次研究中,CT的准确率为65%,MRI的准确率为77.5%,而联合检查的准确率95%。CT的灵敏度为72.92%,MRI的灵敏度为83.33%,联合检查的灵敏度为95.83%。CT的特异度为53.13%,MRI的特异度为68.75%,联合检查的特异度为93.75%。联合检查与CT和MRI相比,差异有统计学意义(P<0.001),其中,准确率、灵敏度、特异度分别为95.00%、95.83%、93.75%。联合检查在诊断准确性上优于单独使用CT或MRI。结论CT和MRI的联合检查用于诊断膝关节骨折周围韧带和肌腱损伤具有较高的诊断效能,准确率、灵敏度、特异度分别为95.00%、95.83%、93.75%,值得临床推广。Objective Exploring the varying diagnostic benefits of CT and magnetic resonance imaging in ligament and tendon injuries around knee joint fractures is the objective.Methods Select 80 patients with knee joint fractures accompanied by peripheral ligament and tendon injuries as the research subjects.The patients were divided into three categories based on the type of examination:CT,MRI,and joint inspection.Subsequently,the exactness,sensitivity,and precision of each single examination was compared and evaluated.Results①48 suspected cases were diagnosed by the"gold standard"examination,and the diagnosis rate was 60.0%.There were 35 patients with positive CT examination,40 patients with positive MRI examination and 46 patients with positive combined examination.②In this study,the accuracy of CT is 65%,the accuracy of MRI is 77.5%,and the accuracy of combined examination is the highest,reaching 95%.The sensitivity of CT is 72.92%,that of MRI is 83.33%,and the sensitivity of combined examination is the highest,which is 95.83%.The specificity of CT is 53.13%,the specificity of MRI is 68.75%,and the specificity of combined examination is the highest,which is 93.75%.Compared with CT and MRI,the combined examination showed significant statistical differences(P<0.001),in which the accuracy,sensitivity and specificity were 95.00%,95.83%and 93.75%respectively.Combined examination is superior to CT or MRI alone in diagnostic accuracy.Conclusion The combined examination of CT and MRI has high diagnostic efficiency in the diagnosis of ligament and tendon injuries around knee joint fractures,with accuracy,sensitivity and specificity of 95.00%,95.83%and 93.75%respectively,which is worthy of clinical promotion.
