IRON DEPOSITION
The primary objective of this study was to examine whether there is a relationship between brain iron dynamics and BBB function during childhood. Considering the accumulative nature of brain iron in the deep gray-matter nuclei, we were interested in the rate of change for regional brain iron deposition over months of age (Δsusceptibility value) rather than the total amount of iron (bulk susceptibility) [To demonstrate the extent to which the choice of assumed ATT affects the For the assessment of the relationship between the rate of change for regional brain iron deposition and the water exchange rate across the BBB, scattergrams between the Δsusceptibility and
