| 中文摘要: |
| 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。 |

| Objective To evaluate the value of DTI in mild articular cartilage injury in patellofemoral joint. Methods The DTI and arthroscopy data of 82 patients wih routine MRI diagnosed as mild articular cartilage injury were analyzed retrospectively. According to the results of arthroscopy, 40 cases of mild articular cartilage injury with Outerbridge classification Ⅰ or Ⅱ were divided into experimental group, and 33 cases with normal patellofemoral articular cartilage were divided into control group. There were 8 articular cartilage injury patients with Outerbridge classification Ⅲ or Ⅳ in patello-femoral join were excluded. The DTI data were analyzed compared with arthroscopy. Results Arthroscopy detected 62 lesions of cartilage injury in experimental group. Totally 49 lesions (49/62, 79.03%) were detected by ADC pseudocolor image and 51 lesions (51/62, 82.25%) were detected by FA pseudocolor image. The DTI pseudocolor images of articular cartilage injury showed uneven levels. The red or pink levels can been observed. Compared with the control group, ADC value increased and FA value decreased significantly in experimental group (both P＜0.05). Conclusion DTI can clearly display and detect mild articular cartilage injury in patellofemoral joint, which provide valuable information for early cartilaginous injury. |
