摘要

背景:儿童和青少年高分辨率超声中神经横断面积(CSA)参考值受人口统计学和人体测量学因素如年龄、身高和体重的影响。目的:在一项前瞻性横断面研究中,评估了手体积作为附加形态测量因子的影响,并分析神经回声性。方法:对30例2 ~ 17岁的健康儿童和青少年进行正中神经、尺神经、桡神经、胫神经、腓神经和腓肠神经的CSA测定。记录身高、体重、年龄、利手性和性别,用水置换法测量手的体积。计算神经内CSA变异性(INV)、左/右比值和绝对差值。通过Kruskal-Wallis测试对年龄组进行比较。采用Spearman相关和多元线性回归分析人口统计学因素的影响。测定各神经节段回声强度及黑色部分。结果:神经CSA值始终低于成人报告的值,并且所有测量的神经部位与年龄、身高、体重和手体积相关。权重的相关系数最高(R = 0.95),是预测CSA的最佳拟合模型。线性模型的相关系数高于对数模型。比率稳定,绝对差异随年龄增加而增加,年龄组间差异显著。多数神经表现为混合型或低回声型,高回声型少见。结论:儿童和青少年的神经CSA低于成人,在生长过程中呈比例增加,不同年龄组的INV和左/右比值不变。体重和年龄是预测神经大小的主要人体测量因素。手体积与神经大小相关,但不能独立预测CSA。回声可提供神经结构的附加信息。

Nerve ultrasound reference values in children and adolescents: Echogenicity and influence of anthropometric factors including hand volume.

Background: Nerve cross-sectional area (CSA) reference values in high-resolution ultrasound for children and adolescents are influenced by demographic and anthropometric factors such as age, height and weight.

Objectives: The influence of hand volume as an additional morphometric factor was evaluated and nerve echogenicity was analyzed in a prospective cross-sectional study.

Methods: CSA were measured in 30 healthy children and adolescents from 2 to 17 years in the median, ulnar, radial, tibial, peroneal and sural nerves. Height, weight, age, handedness and gender were recorded, the volume of the hands was measured using the water displacement method. The intra-nerve CSA variability (INV), left/right ratios and absolute differences were calculated. Age groups were compared by the Kruskal-Wallis test. The influence of demographic factors was analyzed using Spearman correlation and multiple linear regression. Echogenicity and fraction of black were determined for each nerve segment.

Results: Nerve CSA values were consistently lower than those reported for adults and correlated in all measured nerve sites with age, height, weight and hand volume. Weight showed the highest correlation coefficient (R = .95) with the best fitting model predicting CSA. Correlation coefficients were higher in a linear than in a logarithmic model. Ratios were stable, the absolute differences increased with age and were significantly different between age groups. Most nerves showed a mixed or hypoechogenic pattern in echogenicity analysis, hyperechogenicity is less frequently observed.

Conclusions: Nerve CSA in children and adolescents is lower than in adults and increases proportionally during growth with a constant INV and left/right ratio in different age groups. Weight and age are predominant anthropometric factors predicting nerve size. Hand volume is correlated with nerve size, but does not predict CSA independently. Echogenicity can provide additional information on nerve structure.
