[The MR scan of triangular fibrocartilaginous complex injuries].

This review examines whether MRI can reliably replace wrist arthroscopy in diagnosing TFCC injuries of the ulnar wrist, based on 18 articles selected through PubMed, Embase, and Cochrane Library. MRI shows improvement in diagnosing TFCC injuries, and the predictive values of MRI get significantly better by using tools like post-processing techniques, contrast, and pathological markers. However, MRI is unreliable as an independent diagnostic tool for TFCC lesions that need surgical treatment.
