White light and single fluorescence channel acquisition of harvested brain and spinal cord with the in-vivo MS FX PRO Multispectral Imager System. Brightness and contrast have been uniformly adjusted for optimal visualisation. a White light enabled spinal level localisation. b Macroscopic appearance of tracer distribution. There is a sharp drop off in fluorescence intensity within 1–2 spinal levels rostral and caudal to injection site at C7/8 (arrow)
