Purpose

Magnetic resonance imaging is the method of choice for the evaluation of brachial plexus pathology. In this pictorial exhibit, we will review technical aspects of brachial plexus MRI as well as MR anatomy and pathology of the brachial plexus. High-resolution imaging with well defined protocols is necessary for technical success, and basic sequence parameters will be discussed. The anatomy of the brachial plexus roots, trunks, divisions and cords is well depicted due to inherent contrast differences between nerves and the surrounding fat, a feature that will be illustrated in the exhibit through interactive labels. The following pathology, with imaging examples, will be also be addressed: neurogenic tumors of the brachial plexus and sympathetic chain, superior sulcus tumor, other tumors in the vicinity of the brachial plexus, the differentiation between radiation and metastatic plexopathy, trauma, neurogenic thoracic outlet syndrome and immune-mediated neuropathies.
