Preterm brain WM maturational changes from 33 weeks GA to term-equivalent age
pWhole-brain
In the preterm brain, from the 33rd week GA to term-equivalent age we find a statistically significant (pWM fibers with increased FD, FC and FDC from the 33rd week GA to term-equivalent age in very preterm infants’ brain. Population template axial views, from inferior to superior (left to right), of the streamline segments cropped from the template tractogram to include only streamline points that correspond to significant fixels (pWhole-brain macrostructural increases of FC were generally more pronounced (until 50% of increase) than microstructural FD increases (until 20% of increase). The WM fibers with the highest FD, FC and FDC increase from the 33rd week GA to term-equivalent age were the projection fibers (
