摘　　要：目的:分析比较磁共振成像(MRI)与数字化X射线摄影(DR)在急性膝关节损伤诊断中的效能。方法:回顾性分析2021年1月-2023年4月梅州市第二中医医院收治的80例急性膝关节损伤患者(129膝)病例资料。以关节镜检查结果作为金标准,比较MRI与DR各单项检查以及二者联合使用在急性膝关节损伤诊断中的诊断效能。结果:DR诊断急性膝关节损伤中,半月板损伤准确度为85.27%(110/129),Kappa值为0.71;韧带损伤准确度为82.95%(107/129),Kappa值为0.64;骨骼损伤准确度为87.60%(113/129),Kappa值为0.74;MRI诊断急性膝关节损伤中,半月板损伤准确度为93.80%(121/129),Kappa值为0.88;韧带损伤准确度为87.60%(113/129),Kappa值为0.73;骨骼损伤准确度为96.12%(124/129),Kappa值为0.92;MRI联合DR诊断急性膝关节损伤中,半月板损伤准确度为95.35%(123/129),Kappa值为0.91;韧带损伤准确度为95.35%(123/129),Kappa值为0.89;骨骼损伤准确度为96.12%(124/129),Kappa值为0.92。MRI检查、联合检查诊断半月板损伤、骨骼损伤准确度均明显高于DR(P<0.05),联合检查诊断韧带损伤准确度高于MRI与DR各单项检查(P<0.05)。结论:MRI与DR在急性膝关节损伤诊断中均具有较高效能,在半月板损伤及骨骼损伤诊断方面MRI优势更高,二者联合采用能有效提高膝关节韧带损伤准确度。Objective:To analyze and compare the efficacy of magnetic resonance imaging(MRI)and X-ray digital radiography(DR)in the diagnosis of acute knee joint injury.Methods:A retrospective analysis was conducted on the data of 80 patients(129 knees)with acute knee joint injury admitted to Meizhou Second Traditional Chinese Medicine Hospital from January 2021 to April 2023.Using the results of arthroscopy as the gold standard,compare the diagnostic efficacy of MRI and DR in the diagnosis of acute knee injury,as well as their combination.Results:The accuracy of DR in diagnosing acute knee joint injury was 85.27%(110/129),with a Kappa value of 0.71;the accuracy of ligament injury was 82.95%(107/129),and the Kappa value was 0.64;the accuracy of bone damage was 87.60%(113/129),with a Kappa value of 0.74;the accuracy of MRI in diagnosing acute knee joint injury with meniscus injury was 93.80%(121/129),and the Kappa value was 0.88;the accuracy of ligament injury was 87.60%(113/129),with a Kappa value of 0.73;the accuracy of bone damage was 96.12%(124/129),with a Kappa value of 0.92;the accuracy of MRI combined with DR in diagnosing acute knee joint injury with meniscus injury was95.35%(123/129),and the Kappa value was 0.91;The accuracy of ligament injury was 95.35%(123/129),and the Kappa value was 0.89;The accuracy of bone damage was 96.12%(124/129),with a Kappa value of 0.92.The accuracy of MRI examination and joint examination in diagnosing meniscus injury and bone injury was significantly higher than that of DR(P<0.05),while the accuracy of joint examination in diagnosing ligament injury was higher than that of MRI and DR individual examinations(P<0.05).Conclusion:Both MRI and DR have high efficacy in the diagnosis of acute knee joint injury,and MRI has higher advantages in the diagnosis of meniscus injury and bone injury.The combination of the two can effectively improve the accuracy of knee joint ligament injury.
