摘要

腰骶神经丛（LSP）包括一个复杂的神经网络，供应骨盆和下肢，并可能受到多种疾病的影响。腰骶神经丛病由于重叠的临床表现和对深盆腔结构进行电诊断测试的困难，诊断具有挑战性。mri -更具体地说，MR神经成像(MRN)-可以很容易地描述大多数LSP段。MRN技术，最好在3.0 T时进行，继续发展，大多数协议包括二维和可选的三维，重t2加权脂肪抑制序列。本文提供了优化LSP MRN的技术技巧，以及各种LSP相关病理条件的概述，并附有说明性示例。©RSNA， 2025本文可获得补充材料。请参阅本期Chhabra的特邀评论。

MR Neurography of the Lumbosacral Plexus: Technique and Disease Patterns.

The lumbosacral plexus (LSP) comprises a complex network of nerves supplying the pelvis and lower extremities and may be affected by a wide range of diseases. Lumbosacral plexopathy can be challenging to diagnose due to overlapping clinical presentations and difficulty performing electrodiagnostic testing of the deep pelvic structures. MRI-more specifically, MR neurography (MRN)-can readily depict most LSP segments. MRN techniques, preferably performed at 3.0 T, continue to evolve, with most protocols including two-dimensional and optionally three-dimensional, heavily T2-weighted fat-suppressed sequences. This article provides technical tips for optimizing LSP MRN, as well as an overview of various LSP-related pathologic conditions, with accompanying illustrative examples. ^©RSNA, 2025 Supplemental material is available for this article.

期刊介绍： Launched by the Radiological Society of North America (RSNA) in 1981, RadioGraphics is one of the premier education journals in diagnostic radiology. Each bimonthly issue features 15–20 practice-focused articles spanning the full spectrum of radiologic subspecialties and addressing topics such as diagnostic imaging techniques, imaging features of a disease or group of diseases, radiologic-pathologic correlation, practice policy and quality initiatives, imaging physics, informatics, and lifelong learning. A special issue, a monograph focused on a single subspecialty or on a crossover topic of interest to multiple subspecialties, is published each October. Each issue offers more than a dozen opportunities to earn continuing medical education credits that qualify for AMA PRA Category 1 CreditTM and all online activities can be applied toward the ABR MOC Self-Assessment Requirement.
