title: MR Imaging of Wrist Ligaments.
abstract: This article discusses the normal anatomy and pathologic appearances of the intrinsic and extrinsic wrist ligaments using MR Imaging. Technological advances in surface coil design and higher magnetic field strengths have improved radiologists' ability to consistently visualize these small ligaments in their entirety. Wrist ligament anatomy, in the context of proper physiologic function, is emphasized, including common normal variants, and their appearances on MR imaging. The spectrum of disorders, incorporating overlapping appearances of senescent degenerative changes, and destabilizing ligament tears, is outlined. The diagnostic performance of MR imaging to date for various ligament abnormalities is discussed, along with significant limitations.
