摘　　要：目的 :本文目的主要是介绍和评价“双后交叉韧带征”在膝关节半月板撕裂中的价值。方法 :分析 16例膝关节半月板桶柄样撕裂患者 ,其中男性 11例 ,女性 5例。病史从 2周到 3年。采用超导MR扫描机 ,场强 1.0T。成像序列主要包括 :矢状SET1 W(TR TE 6 0 0 15 ) ,梯度T2 W (6 40 18翻转角 2 0°) ;冠状SET1 W (6 0 0 15 ) ,TSET2 W (45 0 0 96 )。所有患者均经手术证实。结果 :所有患者均显示有“双后交叉韧带征”。其中桶柄样撕裂发生于内侧半月板者 12例 ,发生于外侧半月板者 4例。结论 :“双后交叉韧带征”是半月板桶柄样撕裂的一种特征性表现 。Objective:To introduce and evaluate the diagnostic value of double posterior cruciate ligament (PCL)sign in menisci bucket-handle tear of the knee.Methods:There were tatal 16 patients confirmd by operation, male 11 and female 5.The history was from 2 weeks to 3 years.MR imaging was performed on a 1.0T magnet.The imaging included SE sagittal T 1WI,T 2*WI and coronal T 1WI,T 2WI TSE images. Results:The double PCL sign was showed in all cases.The bucket-handle tear of media meniscus and the lateral meniscus was in 12 cases and 4 cases recpectively.Conclusion:The 'double PCL'sign is a characteristic appearance of bucket-handle tear of the meniscus.It is very useful to confirm the diagnosis of this disease.
