Abstract

Until recently, imaging of peripheral nerves was limited from a technical point of view, as there was no established gold standard study protocol for the purpose of qualitative visualization of nerve trunks in normal and pathological conditions. With technical advances in magnetic resonance imaging and the advent of specialized high-resolution magnetic resonance neurography, it has become possible to visualize peripheral nerves of varying diameters. A literature search in the Pubmed, Medline, EMBASE, Cochrane Library, and eLibrary databases demonstrated the presence of several studies examining the capabilities of magnetic resonance imaging in visualizing the pudendal nerve in normal and pathological conditions. It must be emphasized that the results of these studies are consistent and largely complement each other. A generalization of the available data on the capabilities of magnetic resonance neurography of the pudendal nerve was the impetus for writing this literature review. Magnetic resonance neurography is a tissue-specific imaging method optimized for assessing the condition of peripheral nerves, including changes in the morphology of their bundle structure, signal, the diameter and length of nerve trunks, which can be caused by both anatomical features and pathological processes. Three-dimensional (3D) imaging is critical for studying the topography of peripheral nerves, identifying areas of compression or traumatic injury, and for preoperative planning. Magnetic resonance imaging in certain modes and sections allows to clearly visualize the pudendal nerve along almost its entire length, determine the nature of its branching and the features of its topographic and anatomical location. The anatomical characteristics of the pudendal nerve and its pathological changes obtained using magnetic resonance neurography can be used in everyday clinical practice by urologists, obstetricians-gynecologists and neurosurgeons for planning surgical interventions.
磁共振成像在正常和病理情况下阴部神经显像的可能性
直到最近,从技术角度来看,周围神经的成像是有限的,因为在正常和病理状态下,没有确定的神经干定性可视化的金标准研究方案。随着磁共振成像技术的进步和专门的高分辨率磁共振神经成像技术的出现,已经可以可视化不同直径的周围神经。在Pubmed, Medline, EMBASE, Cochrane Library和图书馆数据库中进行的文献检索显示,有几项研究检查了磁共振成像在正常和病理条件下阴部神经可视化方面的能力。必须强调的是,这些研究的结果是一致的,并且在很大程度上是相互补充的。对阴部神经磁共振神经成像能力的可用数据的概括是撰写这篇文献综述的动力。磁共振神经成像是一种组织特异性的成像方法,用于评估周围神经的状况,包括其束结构、信号、神经干直径和长度的形态学变化,这些变化可能是由解剖特征和病理过程引起的。三维(3D)成像对于研究周围神经的地形,识别压迫或创伤性损伤区域以及术前计划至关重要。磁共振成像在某些模式和切片允许清楚地看到阴部神经沿其几乎整个长度,确定其分支的性质及其地形和解剖位置的特征。核磁共振神经造影所获得的阴部神经的解剖特征及其病理变化,可用于泌尿科、妇产科和神经外科医生的日常临床实践,以规划手术干预。
