The aim of this study was to assess different aspects of reliability in high-resolution ultrasonography (HRUS) of the peripheral nerves and to establish reference values for the most frequently examined nerve segments.
A nerve size parameter, the cross-sectional area (CSA) of the C5, C6 and C7 cervical roots, the median, ulnar, radial, superficial radial, peroneal, tibial, and the sural nerves was measured using HRUS at a total of 14 predefined anatomical sites in two different cohorts of healthy subjects (n = 56), and the inter-rater, intra-rater and inter-equipment reliability of measurements was assessed.
The mean CSA of the 14 nerve segments ranged from 2 to 10 mm(2). The intra-rater, inter-rater and inter-equipment reliability was high with intraclass correlation coefficients of 0.93, 0.98, and 0.86, respectively. The CSA values showed no consistent correlation with age, height, and body weight, but males had significantly larger values than females for nerve segments on the arm after correcting for age, weight and height in multivariate analysis. CSA values did not differ when two independent cohorts were compared.
Peripheral nerve ultrasonography is a reliable and reproducible diagnostic method in the hands of experienced examiners. Normal values for several upper and lower extremity nerves are provided by our study.
本研究旨在评估外周神经高分辨率超声检查（HRUS）可靠性的不同方面，并为最常检查的神经节段建立参考值。
使用HRUS在两组不同的健康受试者（n = 56）的总共14个预定义解剖部位测量神经大小参数，即C5、C6和C7颈神经根、正中神经、尺神经、桡神经、桡浅神经、腓总神经、胫神经和腓肠神经的横截面积（CSA），并评估测量的评分者间、评分者内和设备间可靠性。
14个神经节段的平均CSA范围为2至10mm²。评分者内、评分者间和设备间可靠性较高，组内相关系数分别为0.93、0.98和0.86。CSA值与年龄、身高和体重无一致相关性，但在多变量分析中校正年龄、体重和身高后，男性手臂上神经节段的值明显大于女性。比较两个独立队列时，CSA值无差异。
在外周神经超声检查在经验丰富的检查者手中是一种可靠且可重复的诊断方法。我们的研究提供了几条上肢和下肢神经的正常值。
