The aim of this study is to present a fast and
high-resolution MRI scanning technique focused on the
study of peripheral nerves. We used a 3T MRI scanner
with a readily available coil, optimized for clinical
peripheral nerve evaluation. Sequences were based on 3D
spoiled gradient echo combined with the 3-point-Dixon
technique. This protocol provides a combination of high
spatial resolution and adequate SNR with robust and
consistent fluid-fat separation in a single acquisition,
thereby microscopic nerve components can be visualized.
MR micro-neurography may complement standard MR
neurography protocols, for focused evaluation of a
selected nerve tract.
