Diffusion-weighted MR neurography for the assessment of brachial plexopathy in oncological practice.

Background: To evaluate diffusion-weighted MR neurography (DW-MRN) for visualizing the brachial plexus and for the assessment of brachial plexopathy.

Methods: 40 oncological patients with symptoms of brachial plexopathy underwent 1.5 T MRI using conventional MR sequences and unidirectional DW-MRN.
