Compared with the upper limbs, sonographic tracking of peripheral nerves in the lower limbs is more challenging. The overlying muscles are larger, hindering visualization of the deeply embedded nerves by using a linear transducer. The use of a curvilinear transducer-providing an extended view with better penetration for the field of interest-may be useful for scanning the nerves in the hip and thigh. Application of the Doppler mode helps localization of the target nerve by identifying the accompanying vessels. Aiming to demonstrate the relevant tracking techniques, the present article comprises a series of ultrasound images and videos showing how to scan the nerves in the lower limb, that is, femoral, obturator, pudendal, lateral femoral cutaneous, sciatic, saphenous, sural, tibial, and peroneal nerves.
与上肢相比，下肢周围神经的超声追踪更具挑战性。下肢上方的肌肉更大，使用线性换能器会妨碍对深部神经的可视化。使用曲线换能器——能提供更广阔视野且对感兴趣区域有更好穿透性——可能有助于扫描髋部和大腿的神经。应用多普勒模式通过识别伴行血管来帮助定位目标神经。为了展示相关的追踪技术，本文包含一系列超声图像和视频，展示了如何扫描下肢的神经，即股神经、闭孔神经、阴部神经、股外侧皮神经、坐骨神经、隐神经、腓肠神经、胫神经和腓总神经。
