In this study, we proposed to use EPR imaging as a tool to map the concentration of melanin inside ex-vivo human pigmented and non-pigmented melanomas and to correlate this cartography with anatomo-pathology. The importance of the pigmentation for EPR measurement was unambiguously demonstrated. Moreover, EPR images accurately reflected the distribution of melanin pigments within melanoma samples.
