摘　　要：目的　评价MRI诊断膝关节半月板桶柄样撕裂的应用价值。方法　经关节镜证实的 2 1例的桶柄样撕裂患者及 11例非桶柄样撕裂患者。采用百胜公司的关节专用磁共振成像系统进行扫描。观察以下 4种MRI征象 ,双前角征 ,双后交叉韧带征 ,髁间碎片征及领结消失征。结果　 3 2例患者中 ,出现双前角征的有 10例 ,双后交叉韧带征 5例 ,髁间碎片征 2 0例 ,领结消失征 2 5例。结论　MRI是诊断半月板桶柄样撕裂的有效手段 ,内侧半月板桶柄样撕裂的敏感性及特异性较外侧高 。Objective To evaluate the diagnostic value of MRI for meniscal bucket-hanle tears. Methods 21patients with bucket-handle tears and 11 patients without bucket-handle tears were put under MRI examinations with the dedicated MRI system(Artoscan 0.2T ESAOTE) and confirmed by arthroscopy.Each was accessed for the presence of (1) the double-anterior sign,(2)the double posterior cruciate ligament sign,(3)the fragment within the intercondylar notch sign and (4)the absent bow tie sign.Results Of 33 cases, the double-anterior sign were seen in 10 cases, the double posterior cruciate ligament sign were seen in 5 cases,the fragment within the intercondylar notch sign were seen in 20 cases and the absent bow tie sign were seen in 25 cases. Conclusion MRI plays an important role in the diagnosis of meniscal bucket-handle tears.The sensitivity and specificity of medial meniscal bucket-handle tears are higher than that of lateral meniscus. The fragment within the intercondylar notch sign is the most valuable sign in diagnosing meniscal bucket-handle tears.
