MR imaging of normal and injured wrist ligaments.

MR imaging is a rapidly evolving modality for examining the ligaments of the wrist. Recent improvements in magnet design and receiver coil technology have allowed consistent visualization of the wrist ligaments. Image quality can be optimized by selection of the proper receiver coil, careful attention to patient comfort and positioning, and selection of a dedicated imaging protocol. The carpal ligaments can be classified as capsular or interosseous ligaments, with the most important interosseous ligaments being the SLL and LTL as well as the triangular fibrocartilage. It is important for radiologists to understand the anatomy of the carpal ligaments in addition to the normal range of MR appearances as basis for comparison with torn or degenerated carpal ligaments.
