Elbow joint: normal anatomy on MR images.

The normal anatomy of the elbow joint in axial, sagittal, and coronal planes was evaluated by comparing 30 magnetic resonance (MR) images of eight healthy volunteers with microtomed cryosections prepared from six cadaver elbows. MR images provided depiction of muscles and tendons, bone marrow, articular cartilage, and neurovascular structures. Cross-referencing of MR images from one plane to another was useful in the evaluation of complicated, obliquely oriented muscle bundles and other soft tissues.
