MR neurography (MRN) has evolved to become a clinically useful imaging modality for evaluating nerve pathologies. Anatomically, nerves are often surrounded by fat and blood vessels, which appear bright on MR images impeding the conspicuity of nerve visualization. Additionally, nerves are tortuous and would be preferable to visualize in three dimensions for proper diagnosis. Various technical advancements in the field of MR imaging in general have led to volumetric acquisitions with uniform fat and blood suppression. These advancements enabled optimized imaging protocols for better visualization of the nerves. This review article discusses some of these technical advancements that enabled current MRN protocols in routine clinical imaging and certain research techniques that may facilitate nerve disorder characterization following interventions.
磁共振神经成像（MRN）已发展成为一种临床上用于评估神经病变的有用成像方式。从解剖学角度来看，神经通常被脂肪和血管包围，这些在磁共振图像上呈现明亮信号，会妨碍神经可视化的清晰度。此外，神经是弯曲的，为了进行准确诊断，最好能在三维空间中对其进行可视化。一般来说，磁共振成像领域的各种技术进步已实现了具有均匀脂肪和血液抑制的容积采集。这些进步促成了优化的成像方案，以便更好地可视化神经。这篇综述文章讨论了其中一些促成当前常规临床成像中MRN方案的技术进步，以及某些可能有助于在干预后对神经疾病进行特征描述的研究技术。
