Abstract
Magnetic resonance neurography (MRN) is recognized as the imaging modality of choice in the evaluation of patients with brachial plexopathy. It adds vital information to the results of the clinical evaluation and electrodiagnostic tests and facilitates patient management. Its indications include both trauma and non-traumatic forms of plexopathy such as inflammatory, neoplastic and compressive. This article will familiarize readers with the routine MRN protocol in clinical practice and discuss the utility of the different sequences. The timing of the scan is important, especially with reference to trauma and this has been discussed. Both the advantages and limitations of MRN have been elaborated upon.
