Computed tomography of the carpal tunnel: a radioanatomical study.

Cross-sectional anatomy of the carpal tunnel was evaluated by computed tomography (CT) on eight cadavers. Prior to CT, the wrists were marked and, subsequently, anatomical cross sections of the specimens were carefully made along the markers. The anatomical section planes closely correlated with the levels of the CT images. Photographs of one of the specimens were taken for comparative studies.
