Objectives:
Imaging studies of peripheral nerves have increased considerably in the last ten
years. In addition to the classical and still valid study by ultrasound, new neurographic
techniques developed from conventional morphological sequences (including 3D isotropic studies with fat suppression) are making it possible to assess different peripheral nerves and
plexuses, including small sensory and/or motor branches, with great precision. Diffusionweighted sequences and diffusion tensor imaging have opened a new horizon in neurographic
studies. This new approach provides morphological and functional information about the internal structure and pathophysiology of the peripheral nerves and diseases that involve them.
This update reviews the different MR neurography techniques available for the study of the
peripheral nerves, with special emphasis on new sequences based on diffusion.
