Myelination as one of the most reliable indicators of postnatal brain maturation and cognitive ability, supports white matter function by facilitating efficient neural signaling and pathway remodeling. The current study aimed to compare in healthy young adults several recently developed myelin mapping metrics including g-ratio, macromolecular proton fraction, and metrics from diffusion tensor/kurtosis imaging. Relationships between these individual metrics and their specific sensitivity to different aspects of white matter microstructure are discussed.
