Interventional magnetic resonance (MR) neurography is a minimally invasive technique that affords targeting of small nerves in challenging areas of the human body for highly accurate nerve blocks and perineural injections. This cross-sectional technique uniquely combines high tissue contrast and high-spatial-resolution anatomic detail, which enables the precise identification and selective targeting of peripheral nerves, accurate needle guidance and navigation of the needle tip within the immediate vicinity of a nerve, as well as direct visualization of the injected drug for the assessment of appropriate drug distribution and documentation of the absence of spread to confounding nearby nerves.
介入性磁共振（MR）神经成像术是一种微创技术，可针对人体具有挑战性的区域内的小神经进行靶向定位，以实现高度精确的神经阻滞和神经周围注射。这种横断面技术独特地结合了高组织对比度和高空间分辨率的解剖细节，能够精确识别和选择性靶向周围神经，在神经附近精确引导针头并导航针尖，还能直接观察注射药物，以评估药物的适当分布情况，并记录药物未扩散至附近混淆神经的情况。
