High-resolution 3-T MR neurography of femoral neuropathy.

Abstract

The femoral nerve is subject to a variety of diseases that may affect the nerve anywhere from the nerve roots to the distal branches. High-resolution 3-T MR neurography (MRN) is being increasingly used for peripheral nerve evaluation because it complements information gained from electrodiagnostic testing. There are scattered case reports describing femoral nerve diseases using MRI. This article comprehensively reviews different pathologic abnormalities involving the femoral nerve and illustrates their MRN features with case examples.
