Demystifying MR Neurography of the Lumbosacral Plexus: From Protocols to Pathologies

Abstract EN

Magnetic resonance neurography is a high-resolution imaging technique that allows evaluating different neurological pathologies in correlation to clinical and the electrophysiological data.

The aim of this article is to present a review on the anatomy of the lumbosacral plexus nerves, along with imaging protocols, interpretation pitfalls, and most common pathologies that should be recognized by the radiologist: traumatic, iatrogenic, entrapment, tumoral, infectious, and inflammatory conditions.

An extensive series of clinical and imaging cases is presented to illustrate key-points throughout the article.
