摘　　要：目的探讨高频超声显示臂丛神经的可行性及方法学。方法用高频超声检查12例正常人臂丛神经,确认其与周围组织解剖定位关系。结果正常臂丛神经长轴显示多条线性平行回声,短轴呈圆形中等回声,内有点状弱回声,斜角肌间隙、锁骨下动脉和颈深动脉是检查中的重要标志,C5-7显示率100%(12/12例),C8、T1显示率83.3%(10/12例)。结论高频超声可为臂丛神经的形态学观察提供新的影像检查方法。Objective To explore the feasibility and methodology of brachial plexus imaging by high- frequency ultrasonography. Methods Twelve healthy volunteers were examined by high-frequency ultrasonography to depict the nerves and neighbouring structures of the brachial plexus from the extraforaminal part to the axillary part. Results The normal brachial plexus appeared as tubular echogenic structure with parallel linear echo on long axis views, and as a round echogenic structure with punctiform echoes on transverse scans. The scalene muscle, subclavian and deep cervical arteries were useful landmarks for this mapping. The feasibility of C5-7 imaging was 100% （12/12） ,and the feasibility of C8, T1 imaging was 83.3% （10/12）. Conclusions High-frequency ultrasonography provides good quality brachial plexus ultrasound images and shows great potential in noninvasive diagnosis of brachial plexus lesions.
