【摘要】：目的探讨磁共振T1ρ成像评价膝关节软骨早期退变的临床价值。方法对17例有右膝关节疼痛史的中国男子曲棍球队运动员(运动员组)及50名青年健康志愿者(无症状组),行膝关节T1ρ成像,生成T1ρ图,将髌软骨分为上、中、下层,每层又分为外侧、偏外侧、中间、偏内侧及内侧,共15个ROI,测量T1ρ值;并进行对比分析。结果 T1ρ成像均清晰显示两组共134个膝关节,运动员组双侧膝关节髌软骨相应ROI的T1ρ值均明显高于无症状组(P均0.05)。运动员组右侧膝关节髌软骨各ROI的T1ρ值均高于左侧膝关节(P均0.05)。无症状组左、右侧膝关节间,中层外侧(t=2.426,P=0.019)、中层内侧(t=2.549,P=0.014)、下层内侧(t=2.173,P=0.035)髌软骨T1ρ值差异有统计学意义,余12个ROI的T1ρ值差异均无统计学意义(P均0.05)。结论 T1ρ值可敏感地量化反映膝关节髌软骨形态改变之前的早期退变。
[Abstract]:Objective To evaluate the clinical value of MRI in the evaluation of early degeneration of knee cartilage. Methods A total of 17 Chinese men's hockey team athletes (group of athletes) and 50 young healthy volunteers (asymptomatic group) with right knee pain history were divided into upper, middle and lower layers, and each layer was divided into upper, middle and lower layers. In the middle, the medial and the medial side,15 ROI were measured, and the value of T1 was measured; and the comparative analysis was performed. Results There were 134 knee joints in both groups, and the T1 value of the corresponding ROI in both groups was significantly higher in both groups than in the asymptomatic group (P <0.05). The value of T1 in the right knee joint cartilage of the athlete group was higher than that of the left knee joint (P <0.05). There was no statistical difference between the left and right knee joints of the asymptomatic group, the medial side of the middle layer (t = 2.426, P = 0.019), the medial side of the middle layer (t = 2.549, P = 0.014) and the inner side of the lower layer (t = 2.173, P = 0.035). Conclusion The value of T1 may be sensitive to the early degeneration of the changes in the morphology of the cartilage of the knee joint.
