Imaging rationale of ultra high field MRN in experimental DPN. Schematic of the lumbosacral plexus with indication of imaging regions. The upper two images show normal morphological T2-w images of both sciatic nerves (white arrows) within the multicontrast imaging region of the lumbosacral plexus and at the pelvic exit in an axial orientation (a). Lower image depicting a normal axial T2-w image plane of the sciatic nerve along the proximal thigh (b), also indicated by a white arrow. For better orientation, the spinal canal in the image center, surrounded by the hypointense lumbar vertebral column, is indicated by red asterisks.
