Abstract: Pain and weakness in the low back, pelvis, and lower extremities are diagnostically challenging, and imaging can be an important step in the workup and management of these patients. Technical advances in magnetic resonance neurography (MRN) have significantly improved its utility for imaging the lumbosacral plexus (LSP). In this article, the authors review LSP anatomy and selected pathology examples. In addition, the authors will discuss technical considerations for MRN with specific points for the branch nerves off the plexus.<br />Competing Interests: Disclosure Hospital for Special Surgery maintains institutional research agreements with GE Healthcare and Siemens.<br /> (Copyright © 2023 Elsevier Inc.
