Continued advancements in magnetic resonance (MR) neurography and ultrasound have made both indispensable tools for the workup of peripheral neuropathy. Ultrasound provides high spatial resolution of superficial nerves, and techniques such as "sonopalpation" and dynamic maneuvers can improve accuracy. Superior soft tissue contrast, ability to evaluate both superficial and deep nerves with similar high resolution, and reliable characterization of denervation are strengths of MR neurography. Nevertheless, familiarity with normal anatomy, anatomic variants, and common sites of nerve entrapment is essential for radiologists to use both MR neurography and ultrasound effectively.
磁共振神经成像和超声技术的不断进步，使它们成为周围神经病变检查不可或缺的工具。超声提供了浅表神经的高空间分辨率，而“超声触诊”和动态操作等技术可以提高准确性。磁共振神经成像的优势在于具有优越的软组织对比度，能够以类似的高分辨率评估浅表和深部神经，并且能够可靠地描述去神经支配。然而，放射科医生要有效地使用磁共振神经成像和超声，熟悉正常解剖结构、解剖变异和常见神经卡压部位是必不可少的。
