Quantitative sonographic parameters of the peripheral nerves in healthy individuals

Cover Page

Abstract

Introduction. Ultrasonography allows non-invasive scanning of the peripheral nerves to record quantitative and qualitative parameters.

Objective. To determine the normal cross-sectional area (CSA) of the nerves in arms and legs, as well as spinal nerves in healthy volunteers.

Materials and methods. Bilateral ultrasonography of the peripheral nerves in arms and legs, as well as the spinal nerves in the brachial plexus was carried out in healthy volunteers: 40 males and 40 females with the mean age of 40.3±15.1 (range, 18–70 years). A Sonoscape S20 ultrasound scanner (China) with an 8–15 MHz linear sensor. The cross-sectional area of the peripheral nerves was assessed. Height, weight, the body mass index (BMI), age, and gender were included in analysis.

Results. The reference CSA values for the major nerves of arms, legs, and spinal nerves of the brachial plexus were obtained. No reliable correlation of the main anthropometric parameters (height, weight, and BMI) as well as age and gender with the CSA of the peripheral nerves and the brachial plexus was found.

Conclusions. The findings are in accordance with the measured parameters reported by other authors, indicating that our methodological approach to nerve ultrasonography is similar to those used in other laboratories.
