摘要/Abstract

摘要： 目的探讨3.0 T磁共振成像诊断半月板后根部撕裂的诊断准确性。方法收集326例经关节镜证实且有完整磁共振资料的膝关节病例,2名医师在未知关节镜结果的前提下共同评价磁共振图像,并以膝关节镜检查结果为金标准,分析半月板后根部撕裂的准确性,包括诊断的敏感性、特异性和准确率。结果在纳入的326例患者中,经膝关节镜证实为半月板后根部撕裂的患者56例,其中内侧半月板后根部撕裂41例,外侧半月板后根部撕裂15例。内侧半月板后根部撕裂的3.0 T磁共振诊断敏感性、特异性和准确率分别为97.56%、 94.39%和94.79%;外侧半月板后根部撕裂3.0 T MRI诊断敏感性、特异性和准确率分别为73.33%、88.42%和87.73%。内侧半月板后根部撕裂的诊断敏感性、特异性及准确率均高于外侧(χ²=5.228,P=0.022;χ²=6.636,P=0.010;χ²=10.170,P=0.001)。结论 3.0 T磁共振成像对半月板后根部撕裂的诊断准确性较高。

Abstract: Objective To investigate the diagnostic accuracy of 3.0 T MRI in the diagnosis of the medial and lateral meniscal posterior root tears. Methods 326 cases of knee joint confirmed by arthroscopy and with complete MRI data were collected. Under the premise of unknown arthroscopic results, the two physicians jointly evaluated the MRI images and analyzed the accuracy of posterior root tear of meniscus, including the sensitivity, specificity and accuracy of diagnosis. Results Fifty six of the 326 patients were diagnosed with meniscus posterior root tears by arthroscopy, including 41 cases of medial posterior root tears and 15 cases of lateral posterior root tears. The sensitivity, specificity and accuracy of 3.0 T MRI were 97.56%, 94.39% and 94.79%, respectively. The sensitivity, specificity and accuracy of 3.0 T MRI were 73.33%, 88.42% and 87.73%, respectively. The diagnostic sensitivity, specificity, and accuracy of posterior root tear of the medial meniscus are higher than those of the lateral meniscus(χ²=5.228,P=0.022;χ²=6.636,P=0.010;χ²=10.170,P=0.001). Conclusion 3.0 T MRI has high accuracy in the diagnosis of posterior root tears of meniscus.
