| 摘 要： | 目的 探讨DTI评估髌股关节软骨轻度损伤的价值。方法 回顾性分析82例常规MR诊断髌股关节软骨正常或轻度损伤患者的DTI及关节镜检查资料。根据关节镜检查结果，将其中40例Outerbridge分级Ⅰ、Ⅱ级者纳入髌股关节软骨轻度损伤组，33例无髌股关节软骨损伤者纳入对照组，排除9例Outerbridge分级为Ⅲ、Ⅳ级者。对比分析2组髌股关节软骨DTI表现，并与关节镜结果对照。结果 髌股关节软骨轻度损伤组40例关节镜检查共发现62处软骨轻度损伤；其中通过ADC及伪彩图可显示49处（49/62，79.03%），FA伪彩图可显示51处（51/62，82.25%）。髌股关节软骨轻度损伤ADC及FA伪彩图表现为软骨色阶不均匀，内见红色或粉色色阶。与对照组正常软骨比较，髌股关节软骨轻度损伤组软骨损伤区ADC值明显增高，FA值明显降低（P均＜0.05）。结论 DTI可显示及量化髌股关节软骨的轻度损伤，为早期软骨损伤的诊治提供有价值的参考信息。
