Ultrasonography can be used in the diagnosis of various neuropathies, including nerve injury. Nerves often involved in traumatic and iatrogenic injury are small cutaneous branches in the hand and wrist, which cannot be seen in detail using current ultrasound probes. This study explored the potential of high-resolution ultrasonography in seeing these nerve branches in the human. The VisualSonics Vevo 770 system with a 15-82.5 MHz probe was compared to a commonly used 5-12 MHz probe and ultrasound machine. The accuracy was validated by ultrasound guided dye injection into cadaver nerves, with subsequent anatomical dissection and verification. Results were confirmed in two healthy volunteers. The Vevo 770 system was able to accurately identify the small cutaneous nerves. It could also depict the median nerve and its fascicles in greater detail. This may be useful for clinical diagnosis, localisation and follow-up of neuropathies and nerve injuries.
超声检查可用于诊断各种神经病变，包括神经损伤。手部和腕部的小皮支神经常受累于创伤性和医源性损伤，使用目前的超声探头无法详细观察到这些神经。本研究探讨了高分辨率超声在观察人体这些神经分支方面的潜力。将配备15 - 82.5 MHz探头的VisualSonics Vevo 770系统与常用的5 - 12 MHz探头及超声仪进行了比较。通过超声引导下向尸体神经注射染料，随后进行解剖和验证来验证准确性。在两名健康志愿者身上证实了结果。Vevo 770系统能够准确识别小皮神经。它还能更详细地描绘正中神经及其束。这可能对神经病变和神经损伤的临床诊断、定位及随访有用。
