目的：探讨年龄和早期症状性退变是否改变了T2关节软骨的空间依赖性。材料和方法：在25名无症状志愿者和6名有膝关节软化症症状的志愿者中，使用多回波自旋回波磁共振成像序列获得了位于3.0T的定量的T2图，T2的空间变异被评估为功能DF参与者的年龄和症状。在46-60岁人群中，与年轻志愿者相比，差异有统计学意义(P
PURPOSE: To determine if age and early symptomatic degeneration alter the spatial dependency of cartilage T2.MATERIALS AND METHODS: In 25 asymptomatic volunteers and six volunteers with symptoms of patellar chondromalacia, quantitative T2 maps of patellar cartilage were obtained with a multiecho, spin-echo magnetic resonance imaging sequence at 3.0 T. Spatial variation in T2 was evaluated as a function df participant age and symptoms.RESULTS: All asymptomatic volunteers demonstrated a continuous increase in T2 from the radial zone to the articular surface. In the population aged 46-60 years compared with younger volunteers, there was a statistically significant (P
