MRI metrics such as T1w/T2w ratio, magnetization transfer ratio (MTR), myelin water faction (MWF) and diffusion kurtosis imaging (DKI) indices have been used to detect myelin content. To assess the sensitivity of above metrics to variation of myelin content, in vivo human corpus callosum is used as a test case in the study. The results suggest that MTR varies least but MWF varies the most as myelin content changes.
