| 摘 要： | 目的：测量不同程度膝关节骨关节炎（osteoarthritis,OA）患者和正常对照组关节软骨的T2弛豫时间并比较其差异性,评价磁共振T2-mapping成像在早期膝关节软骨损伤中的应用价值。方法：采用GE signa 3.0T磁共振扫描系统T2-mapping成像测量OA组（n=78）和正常组（n=32）膝关节股骨内侧髁、外侧髁,胫骨内侧髁、外侧髁4处软骨的T2值,并进行统计学分析。结果：正常组、轻度OA组、重度OA组平均T2值分别为（38.36±2.45）ms（、49.28±4.24）ms、（53.12±5.36）ms,病例组与对照组关节软骨表面T2值有差异且具显著性统计学意义（P〈0.05）,轻度OA组和重度OA组之间差别无统计学意义（P〉0.05）。结论：T2-mapping成像可以发现没有形态学改变的关节软骨内组织成分的变化,对早期膝关节软骨损伤的诊断和监测具有很高的临床应用价值。
