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(P<0.05)。结论 T2mapping成像可用于评价肩关节软骨构成成分变化。
Objective To investigate the feasibility of T2 mapping in evaluating the composition of shoulder cartilage,and to quantitatively analyze T2 values of articular cartilage in healthy young volunteers.Methods Oblique coronal T2 mapping imaging with 8 echo was performed in bilateral shoulder of 16 young healthy volunteers.The pseudo-color map was obtained with post-processing.The shoulder joint cartilage was equally divided into the external,central and internal zones,and T2 values were measured quantitatively.T2 values in the external,central and internal zones were analyzed and compared.T2 values of cartilage between male and female volunteers as well as between left and right sides were analyzed.Results T2 values in the external,central and internal zones of cartilage were（38.67±2.82）ms,（38.41±2.52）ms and（36.49±1.80）ms,respectively.The overall difference was statistically significant（F=7.789,P=0.001）.T2 values in the external and central zones of cartilage were larger than those in the internal zone（both P0.05）.T2 values of cartilage had no significant differences between the left and right sides in the external,central and internal zones（all P0.05）.There was significant difference of T2 value in the central zone（P0.05）,while no significant difference of T2 value in the external and internal zones between different genders was found（both P0.05）.Conclusion T2 mapping imaging can be used to evaluate the composition of shoulder cartilage changes.
