Kinematic evaluation of the wrist is important in the diagnosis and management of wrist pathology. Altered kinematics can lead to unbalanced joint loading and ultimately, osteoarthritis. Unfortunately, dynamic abnormalities of carpal motion are often missed by static imaging. Using fast imaging techniques such as HASTE, data can be rapidly acquired during normal wrist motion and quickly processed into 2D and 3D cine loops. We show that it is feasible to obtain this data at little time cost; this may prove to be an important addition to routine clinical imaging to provide important kinematic information to the clinician.
