| 目的 探讨MR T2 mapping成像评价正常成年人腕关节三角纤维软骨复合体（TFCC）差异的可行性。方法 对81名健康志愿者行腕关节MR T2 mapping成像，其中30名行双侧腕关节扫描，分为利手组和非利手组。经后处理获得T2 mapping伪彩图，测量桡侧软骨、三角纤维软骨盘（TFC）、纤维血管、类半月板及TFC尺侧附着处T2值。比较不同性别之间、利手组与非利手组之间腕关节软骨不同区域T2值差异。结果 腕关节软骨不同区域T2值差异有统计学意义（F=32.235，P<0.01）。纤维血管组织[（34.22±6.85）ms]与TFC尺侧附着处[（32.57±7.23）ms]、桡侧软骨[（41.37±7.04）ms]与类半月板[（39.26±8.88）ms]T2值差异无统计学意义（P均>0.05），其余软骨各区域间T2值两两比较差异均有统计学意义（P均<0.05）。不同性别间、利手组与非利手组间腕关节不同区域T2值差异均无统计学意义（P均>0.05）。结论 T2 mapping成像可直观显示腕关节TFCC形态，定量分析TFCC不同区域T2值变化，不受性别及是否利手的影响。 |

| Objective To explore the feasibility of evaluation on the differences of wrist triangular fibrocartilage complex (TFCC) with T2 mapping in healthy adults. Methods Totally 81 healthy volunteers underwent T2 mapping of wrist joint. Among them 30 subjects underwent bilateral wrist scanning, and the images were divided into handedness group and non-handedness group according to the handedness questionnaire. All images were postprocessed to obtain T2 mapping pseudo-color images. T2 values of radial cartilage, triangular fibrocartilage disc proper (TFC), fibrous vascular tissue, meniscus and TFC's ulnar attachment were measured. The differences of T2 values in different areas of wrist cartilage were compared between different genders and handedness group and non-handedness group.Results There were statistically differences of T2 values in different regions of wrist cartilage (F=32.235, P<0.01). There was no statistically difference of T2 values of fibrous vascular tissue ([34.22±6.85]ms) and TFC's ulnar attachment ([32.57±7.23]ms), nor T2 values of radial cartilage ([41.37±7.04]ms) and meniscus ([39.26±8.88]ms) (all P>0.05), while there were statistically differences of T2 values of the remaining areas of carpal cartilage (all P<0.05). There was no significant difference of T2 values of wrist TFCC between different genders nor handedness group and non-handedness group (all P<0.05).Conclusion T2 mapping can visually display the morphology of wrist TFCC and quantitatively evaluate changes of T2 values in different regions of TFCC, which are not affected by gender and handedness. |
