To correlate the histologic structure and echotexture of peripheral nerves and verify if ultrasound (US) findings can be used to differentiate nerve from tendon.
In an in vitro study, the echotexture of normal peripheral nerves was correlated with the histologic findings. In an in vivo study, US was used to differentiate median nerve from flexor pollicis longus tendon in healthy volunteers (12 male and eight female subjects 7-68 years of age; mean age, 35 years).
US examination of the peripheral nerve specimens showed hypoechoic areas separated by hyperechoic bands. The hypoechoic areas corresponded to neuronal fascicles at histologic examination. This fascicular pattern was clear in all median and ulnar nerves, 15 of 20 vagus nerves, and 19 of 20 sciatic nerves in the volunteers but not in recurrent laryngeal nerves.
Peripheral nerves have a typical US pattern that correlates with histologic structure and facilitates differentiation between nerves and tendons.
关联外周神经的组织学结构与回声特征，并验证超声（US）检查结果是否可用于区分神经与肌腱。
在一项体外研究中，将正常外周神经的回声特征与组织学检查结果进行关联。在一项体内研究中，利用超声在健康志愿者（12名男性和8名女性，年龄7 - 68岁；平均年龄35岁）中区分正中神经与拇长屈肌腱。
对外周神经标本的超声检查显示，低回声区域被高回声带分隔。在组织学检查中，低回声区域对应于神经束。志愿者的所有正中神经和尺神经、20条迷走神经中的15条以及20条坐骨神经中的19条均呈现出这种束状模式，但喉返神经未呈现。
外周神经具有典型的超声模式，该模式与组织学结构相关，有助于区分神经与肌腱。
