MR imaging of the normal sternoclavicular joint: spectrum of findings.

Although MR imaging has become an important imaging method in the evaluation of most joints, it is rarely used to evaluate the sternoclavicular joint. The purpose of this study was to determine the spectrum of findings identified on MR images of the normal sternoclavicular joint as seen on images of cadavers, healthy volunteers, and patients with normal joints. Knowledge of these findings can prevent misdiagnosis of a normal variant as an abnormality.
