INTRODUCTION
Reported sonographic reference values for the vagus nerves (VNs) vary greatly. We aimed to generate reference values in a large cohort and examine intrarater, interrater, and across-ultrasound systems agreement.
METHODS
The VNs of 60 healthy subjects were examined by 2 sonographers and with 2 ultrasound systems. Cross-sectional areas (CSAs) of each VN were assessed at the level of the carotid sinus [proximal measurement level (ML)] and thyroid gland (distal ML).
RESULTS
Mean VN CSA was significantly larger on the right side (proximal ML: 2.7 ± 0.6 mm vs. 2.1 ± 0.5 mm ; distal ML: 2.6 ± 0.6 mm vs. 1.9 ± 0.4 mm ). VN CSA decreased with increasing age. There were good intrarater, interrater, and across-ultrasound systems agreements.
DISCUSSION
The right VN CSA is significantly larger than the left. These side- and age-specific reference values for the VN may be useful for future studies. Muscle Nerve 57: 766-771, 2018.
简介
报道的迷走神经（VN）的超声参考值差异很大。我们旨在通过大样本量生成参考值，并检查内部、外部和跨超声系统的一致性。
方法
由 2 名超声医师和 2 种超声系统对 60 名健康受试者的 VN 进行检查。在颈动脉窦（近端测量水平（ML））和甲状腺水平（远端 ML）评估每个 VN 的横截面积（CSA）。
结果
右侧 VN CSA 明显大于左侧（近端 ML：2.7±0.6mm 比 2.1±0.5mm；远端 ML：2.6±0.6mm 比 1.9±0.4mm）。VN CSA 随年龄增加而减小。内部、外部和跨超声系统的一致性良好。
讨论
右侧 VN CSA 明显大于左侧。VN 的这些特定于侧和年龄的参考值可能对未来的研究有用。肌肉神经 57:766-771,2018.
