Imaging studies including ultrasound (US) and magnetic resonance imaging may be required to evaluate the median nerve in patients with suspected carpal tunnel syndrome. However, the radial and ulnar nerves contribute to sensory and motor innervations to the hand as well. Compressive, traumatic, and iatrogenic events may damage the small terminal branches of these nerves. In the hand, US is able to identify injuries of the median, ulnar, radial nerve, and terminal branches. This article presents the role of imaging to evaluate the nerves of the hand with an emphasis on US. Due to its high-resolution capabilities, US is useful to determine the location, extent, and type of nerve lesion. Moreover, US is useful for a postsurgical assessment. The anterior interosseous nerve, Guyon's tunnel syndrome, and Wartenberg's syndrome are also described.
对于疑似腕管综合征的患者，可能需要进行包括超声（US）和磁共振成像在内的影像学检查，以评估正中神经。然而，桡神经和尺神经对手部的感觉和运动神经支配也有贡献。压迫性、创伤性和医源性事件可能会损伤这些神经的小终末分支。在手部，超声能够识别正中神经、尺神经、桡神经及其终末分支的损伤。本文介绍了影像学在评估手部神经方面的作用，重点是超声。由于其高分辨率能力，超声有助于确定神经病变的位置、范围和类型。此外，超声对术后评估也很有用。本文还描述了骨间前神经、Guyon管综合征和Wartenberg综合征。
