【摘要】：目的探讨T2mapping成像评价青年健康志愿者肩关节软骨构成成分的可行性,并定量分析肩关节软骨T2值。方法对16名青年健康志愿者行双侧肩关节斜冠状位8回波T2mapping成像,并经后处理获得伪彩图,将肩关节软骨三等分为外带、中带、内带,测量其T2值。比较外带、中带、内带间T2值的差异及不同性别间、左右侧间T2值差异。结果肩关节软骨外带、中带、内带T2值分别为(38.67±2.82)ms、(38.41±2.52)ms、(36.49±1.80)ms,总体差异有统计学意义(F=7.789,P=0.001),肩关节外带、中带软骨T2值均大于内带(P均0.05)。肩关节软骨外带、中带及内带的左侧与右侧T2值、不同性别间肩关节软骨外带、内带T2值差异均无统计学意义(P均0.05)。不同性别间肩关节软骨中带T2值差异有统计学意义(P0.05)。结论 T2mapping成像可用于评价肩关节软骨构成成分变化。
[Abstract]:Objective to evaluate the feasibility of T2mapping imaging in evaluating the composition of shoulder cartilage in young healthy volunteers and to quantitatively analyze the T 2 value of shoulder cartilage. Methods Sixteen young healthy volunteers were performed 8 echo T2mapping imaging in oblique coronal position of bilateral shoulder joint. After post-processing, pseudo-color images were obtained. The cartilage of shoulder joint was divided into external band, middle band and inner band, and its T2 value was measured. The difference of T 2 value between outer zone, middle band and inner band and T 2 value between sexes and between left and right were compared. Results the T2 values of the outer band, middle band and inner band of shoulder articular cartilage were 38.67 卤2.82mnmms38.41 卤2.52mnmsrespectively. The overall difference was statistically significant (P < 0.01). The T2 value of the outer band of shoulder joint and the middle band of cartilage were all higher than that of the inner zone (P < 0.05). There was no significant difference in the left and right T2 values of the articular cartilage band, the middle band and the inner band between the two sexes. There was no significant difference in T2 value between the two sexes (P < 0.05). There was significant difference in T 2 value of middle band of shoulder articular cartilage between sexes (P 0.05). Conclusion T2mapping imaging can be used to evaluate the composition of shoulder cartilage.
