Cerebral blood flow in ROIs on day 4 of life (n = 17) and day 11 of life (n = 20). Box-and-whisker plots show the lower to upper quartiles (box edges), medians (line in boxes) and minimum/maximum values (lines at ends of whiskers). The mark represents the mean. The dot-and-line diagrams (in blue) show infants with both early and late MRI (n = 11). The asterisk represents significant difference [p < .05] [Wilcoxon test for paired samples]. Differences between cortical GM and BGT were significant on both early and late MRI. Difference between frontal and temporal lobes was significant on early MRI. BGT = Basal Ganglia and Thalami; CBF = Cerebral Blood Flow; DOL4 = day 4 of life; DOL11 = day 11 of life; Cortical GM = Grey matter in lobes; ROI = Region Of Interest.
