The aim of this study was to use ultrasound to measure the cervical nerve roots in normal children to determine normal reference values.
A total of 441 children of different ages at the Children's Hospital of Chongqing Medical University were examined by ultrasound. The diameter, circumference, and cross-sectional area of the nerve roots were measured.
Ultrasonographic measurements were consistent with the ranking C5 < C6 < C7. The C8 nerve root was thicker than C7 in 60% of the participants. The nerve root measurements increased with increasing age, height, weight, and body surface area.
Normal reference ranges of the cervical nerve roots in children of different ages were established, and can serve as the basis for measurement in future studies.
本研究旨在通过超声测量正常儿童的颈神经根，以确定正常参考值。
重庆医科大学儿童医院共对 441 名不同年龄的儿童进行了超声检查。测量了神经根的直径、周长和横截面积。
超声测量结果与 C5<C6<C7 的排序一致。60%的参与者 C8 神经根比 C7 粗。神经根测量值随年龄、身高、体重和体表面积的增加而增加。
建立了不同年龄儿童颈神经根的正常参考范围，可为今后的研究测量提供依据。
