【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。
