We aimed to provide data of nerve sizes and echogenicity reference values of the Lithuanian population.
High-resolution ultrasound was bilaterally performed according to the Ultrasound Pattern Sum Score and Neuropathy ultrasound protocols for healthy Lithuanian adults. Cross-sectional area (CSA) measurement and echogenicity were used as the main parameters for investigation. Echogenicity was evaluated using ImageJ, and nerves were categorized in classes according to echogenicity.
Of 125 subjects enrolled, 63 were males (mean age 47.57 years, range 25-78 years) and 62 were females (mean age 50.50 years, range 25-80 years). Reference values of nerve sizes and values of echogenicity as a fraction of black in percentage of cervical roots, upper and middle trunks of the brachial plexus and the following nerves: vagal, median, ulnar, radial, superficial radial, tibial, fibular, and sural in standard regions were established. Mild to moderate correlations were found between nerves CSA, echogenicity values and anthropometric measurements with the differences according to sex. Inter-rater (ICC 0.93; 95% CI 0.92-0.94) and intra-rater (ICC 0.94; 95% CI 0.93-0.95) reliability was excellent.
Reference values of nerve size and echogenicity of Lithuanians were presented for the first time as a novel such kind of publication from the Baltic countries.
我们旨在提供立陶宛人群神经大小和回声参考值的数据。
根据超声模式总和评分和神经病超声协议，对健康的立陶宛成年人双侧进行高分辨率超声检查。使用横截面积（CSA）测量和回声作为主要研究参数。使用ImageJ评估回声，并根据回声将神经分类。
在125名受试者中，63名男性（平均年龄47.57岁，范围25 - 78岁），62名女性（平均年龄50.50岁，范围25 - 80岁）。建立了标准区域中颈神经根、臂丛上干和中干以及以下神经（迷走神经、正中神经、尺神经、桡神经、桡浅神经、胫神经、腓总神经和腓肠神经）的神经大小参考值和作为黑色比例的回声值。发现神经CSA、回声值与人体测量值之间存在轻度至中度相关性，且存在性别差异。评分者间（ICC 0.93；95% CI 0.92 - 0.94）和评分者内（ICC 0.94；95% CI 0.93 - 0.95）可靠性极佳。
首次公布了立陶宛人的神经大小和回声参考值，这是来自波罗的海国家的此类新颖出版物。
