          Understanding healthy brain development is critical for 
						studying developmental disorders. Inhomogeneous 
						magnetization transfer (ihMT) is able to virtually 
						eliminate signal from unmyelinated tissues, and may 
						provide a biomarker specific to myelination, an 
						important part of brain development. We used ihMT and 
						MTI to characterize the white matter (WM) of healthy 
						children aged 2-4 and 8-13 years. While qMT was 
						significantly different in most WM areas between groups, 
						qihMT was only significantly different in the cingulum 
						and genu of the corpus callosum. This indicates 
						myelination in these frontal tracts, while changes in 
						qMT may indicate other maturation changes in 
						macromolecular content.
