To evaluate triangular fibrocartilage complex (TFCC) injury based on quantitative analysis of fibrocartilage by 3.0T MR 3D VIBE and T2 mapping techniques. In this study, 25 patients with TFCC (15 patients with unilateral injury and 10 patients with bilateral injury) and 30 healthy subjects were enrolled. All 55 participants underwent bilateral wrist joint routine plain scan + enhanced scan, 3D VIBE and T2 mapping sequence scan. The 2 hands were divided into the dominant group and the non-dominant hand group. Pseudo-color images of T2 mapping were obtained through the post-processing workstation. Except for the meniscus homologue, there were statistical differences in the overall mean T2 value of all other regions between the injured group and the healthy group (P < .001). The T2 value of each region in the injury group was statistically different in the pairwise comparison (all P < .02). There was no statistical difference in the overall mean T2 value between the dominant hand group and the non-dominant hand group. 3.0T MR 3D VIBE and T2 mapping techniques are helpful for the evaluation of TFCC injury and the quantitative analysis of fibrocartilage. The parameters can reflect molecular changes of fibrocartilage injury, and T2 values are not affected by dominant hand, age and gender.
基于 3.0T MR 3D VIBE 和 T2 映射技术对三角纤维软骨复合体（TFCC）损伤进行定量分析。本研究纳入 25 例 TFCC 患者（单侧损伤 15 例，双侧损伤 10 例）和 30 例健康对照者。所有 55 名参与者均接受双侧腕关节常规平扫+增强扫描、3D VIBE 和 T2 映射序列扫描。双手分为优势手组和非优势手组。通过后处理工作站获得 T2 映射的伪彩图像。除半月板同源物外，损伤组与健康组所有其他区域的整体平均 T2 值均存在统计学差异（P<0.001）。在组间两两比较中，损伤组各区域的 T2 值均存在统计学差异（均 P<0.02）。优势手组与非优势手组的整体平均 T2 值无统计学差异。3.0T MR 3D VIBE 和 T2 映射技术有助于评估 TFCC 损伤和纤维软骨的定量分析。这些参数可以反映纤维软骨损伤的分子变化，并且 T2 值不受优势手、年龄和性别影响。
