Evolution of Apparent Diffusion Coefficient and Fractional Anisotropy in the Cerebrum of Asphyxiated Newborns Treated with Hypothermia over the First Month of Life
Table 3
Comparison of fractional anisotropy (FA) values in each region of interest between healthy newborns and asphyxiated newborns treated with hypothermia developing or not developing brain injury, on day 1 of life, on days 2-3 of life, around day 10 of life, and around day 30 of life.
