Evaluation on the differences of wrist triangular fibrocartilage complex with T2 mapping in healthy adults / 中国医学影像技术

ABSTRACT

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, P0.05), 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.
