Multimodal magnetic resonance imaging of peripheral nerves: Establishment and validation of brachial and lumbosacral plexi measurements in 163 healthy subjects⋆

Highlights: • Multimodal MR of the plexi act as a composite protocol for assessing peripheral nerve. • Multi-parameters for the plexi were provided in a large group of healthy subjects. • Providing normal variances in plexi would be used in detecting subtle abnormalities. - Abstract: Purpose: This study aims to provide normal reference values for quantitative parameters for brachial and lumbosacral plexi on multimodal MRI. In addition, the parameter variations between the left and right sides, the individual nerve groups, genders and age groups were also evaluated.
