- Abstract
Introduction: Ultrasonography allows high-resolution visualisation of the peripheral nerves for quantitative and qualitative analyses. We report cross-sectional area values (quantitative measure) and echo intensity values (qualitative measure) for 46 peripheral nerve sites in upper and lower extremities in cadaveric specimens. Objective: To determine cross-sectional area values and echo intensity values of peripheral nerves of upper and lower extremities at 46 nerve sites. Methods: Nerve measurements were obtained using electronic callipers and ultrasonography for linear dimension and cross-sectional area measurements, respectively, in six cadaveric specimens for 46 peripheral nerve sites. Ultrasound images were further analysed to estimate echo intensity percentage values for 46 nerves. Results: We present normal cross-sectional area values of various nerves of upper and lower extremities with their respective echo intensity values. Calculated cross-sectional area values from linear dimensions did not match the measured cross-sectional area values via trace method. Conclusion: Cross-sectional area values (quantitative measure) and echo intensity values (qualitative measure) for 46 peripheral nerve sites in upper and lower extremities in cadaveric specimens are presented. The estimation of cross-sectional area via linear measurement is not a good approximation of the cross-sectional area (cross-sectional area measured by trace method on ultrasound image).
