Advanced MR Neurography Imaging of Radial Nerve Entrapment at the Spiral Groove: A Case Report

Abstract

High-resolution magnetic resonance neurography (MRN) is being increasingly employed for the evaluation of peripheral nerves. We describe a case of spiral groove syndrome (Saturday night palsy) and illustrate the role of advanced 3 Tesla MRN imaging techniques, including three-dimensional diffusion-weighted fat-suppressed reversed fast imaging with steady-state precession and diffusion tensor imaging.
