Magnetic resonance neurography (MRN) is being increasingly used as a problem-solving tool for diagnosis and management of peripheral neuropathies. This review is aimed at summarizing important technological advances, including MR pulse sequence and surface coil developments, which have facilitated MRN's use in clinical practice.
The most recent research in MRN focuses on its clinical applications, with concomitant development of three-dimensional, parallel imaging and vascular suppression techniques that facilitate higher spatial resolution and depiction of small nerve branches arising from the brachial and lumbosacral plexi as well as fascicular abnormalities of more distal extremity nerves. Quantitative diffusion tensor imaging (DTI) has been studied as a tool to detect microstructural abnormalities of peripheral nerves and more precisely define grades of nerve injury but will require additional investigation to determine its role in daily clinical practice. MRN continues to evolve due to technological improvements and awareness by the medical community of its capabilities. Additional technological developments related to surface coil designs and vascular suppression techniques will be needed to move the field forward.
磁共振神经成像（MRN）作为一种用于诊断和治疗周围神经病变的辅助工具，应用日益广泛。本综述旨在总结 MRN 在临床应用中的重要技术进展，包括脉冲序列和表面线圈的发展，这些进步促进了磁共振神经成像的应用。
磁共振神经成像的最新研究侧重于其临床应用，同时开发了三维、并行成像和血管抑制技术，从而提高了空间分辨率，并能更好地显示臂丛和腰骶丛发出的小神经分支以及更远端肢体神经的束状异常。定量扩散张量成像（DTI）已被研究作为一种检测周围神经微观结构异常的工具，并更准确地定义神经损伤的程度，但需要进一步研究以确定其在日常临床实践中的作用。由于技术的改进和医学界对其功能的认识，磁共振神经成像在不断发展。需要进一步开发与表面线圈设计和血管抑制技术相关的技术进步，以推动该领域的发展。
