Methods and materials
Total of 235 patients with wrist pain (age range 13 to 90 years; mean age 49.0) were evaluated retrospectively in this study after institutional review board approval. All MRI images were obtained using an eight-channel wrist coil on a 3.0 T unit (Achiva TX, Philips Healthcare, Best, Netherlands). Axial 2D FSE PDWI (2mm thickness) and reformatted images from coronal 3D isotropic FS PDWI (0.35 mm voxel size) were reviewed for evaluation of this study. A parallel imaging technique named sensitivity encoding (SENSE) was used in both the 2D and 3D sequences. All 3D images were obtained in combination with the driven equilibrium (DRIVE) technique [13]. Acquisition time was approximately 5 minutes for 3D isotropic MRI images and approximately 2 minutes 30 seconds for 2D FSE sequence. Nine TFCC and TFCC related components (Palmer 1A, 1B, 1C, 1D, volar and dorsal radioulnar ligaments (VRUL and DRUL), ulnar capsule (UC), meniscus homologue, and ECU tendon/sheath) were analyzed. One musculoskeletal fellow and one board certified musculoskeletal radiologist reviewed the cases individually and reached consensus diagnosis of injury. Analysis of individual TFCC and TFCC-related components was done to find out any specific pattern or distribution of injuries.
