Advanced imaging techniques of the brachial plexus

Abstract

The brachial plexus is a complex structure that arises from nerve roots in the neck and terminates by dividing into peripheral nerves in the axilla. Imaging the brachial plexus can be difficult because of this anatomy. MRI now is the imaging modality of choice in the evaluation of brachial plexopathy. T1-weighted axial and oblique coronal images supplemented by T-2 weighted or STIR images are a standard protocol. MRI can be used to diagnose nerve root avulsion, neuromas, tumor, and radiation fibrosis.
