| 摘 要： | 目的：研究正常的和损伤的膝关节交叉韧带的ＭＲＩ表现。材料和方法：对１１０例正常膝关节交叉韧带的ＭＲＩ进行回顾性分析，测量矢状位上前后交叉韧带的宽径；对５４例临床可疑交叉韧带损伤的患者的ＭＲＩ和关节镜检查进行了对比研究。结果：正常膝关节矢状位ＭＲＩ上，前交叉韧带（ＡＣＬ）宽径平均为３．８ｍｍ，后交叉韧带（ＰＣＬ）宽径平均为４．８ｍｍ；交叉韧带损伤的ＭＲＩ表现为韧带连续性中断，局灶性或弥漫性肿胀，信号强度增强及断端移位；以关节镜检查结果为标准，ＭＲＩ诊断交叉韧带损伤的敏感性为９１．７％，特异性为９５．０％，准确性为９２．９％。结论：梯度回波小角度翻转（ｓｍａｌｔｉｐａｎｇｌｅｇｒａｄｉｅｎｔｅｃｈｏ，ＳＴＡＧＥ）序列结合Ｔ１ＷＩ的ＭＲＩ是一种准确诊断交叉韧带损伤的方法。
