摘　　要：目的:探讨MRI扩散加权成像在髌软骨损伤中的诊断价值。方法:使用GE 3T成像装置对8例正常健康志愿者16个膝关节、25例髌软骨损伤患者25个膝关节行常规序列及DWI序列成像。测量髌软骨各个感兴趣区的表观扩散系数(ADC)值,比较各组间的差异。结果:正常健康志愿者组ADC均值为(9.1±2.9)×10-4mm2/s,软骨损伤组髌软骨ADC均值为(11.3±5.0)×10-4mm2/s,两组间差异有统计学意义(t=30.832,P=0.000)。结论:MRI DWI对软骨损伤有较高的诊断价值。Objective：To study the appearance of MR diffusion weighted imaging in patella cartilage injury and to detect its value.Methods：16 knees of 8 healthy volunteers and 25 of patella cartilage injuries were imaged with routine MR sequences and DWI.The ADC of each part of patella cartilage were measured and compared.Results：In healthy volunteers,the ADCav of patella cartilage was（9.1±2.9）×10-4 mm2/s.In patients with cartilage injuries,the ADCav was（11.3±5.0）×10-4 mm2/s.The ADCav of cartilage injury group was higher than that of healthy volunteers（t=30.832,P=0.000）.Conclusion：DWI is a useful method in detecting early cartilage injury.
