Inferior frontal–occipital fasiculus (IFOF) along-tract statistics. In the controls, there were three segmental identified of the IFOF within the fractional anisotropy tract profile which corresponded to the trajectory of the fiber tract extending from the occipital/ temporal lobe (Segment 1), coursing through the external capsule (Segment 2), towards the inferior frontal lobe (Segmental 3). When comparing this FA tract profiles to the preterm PVL cases, the greatest reduction in FA occurred in Segment 1 and Segment 2, with a greater reduction noted within the occipital portion of the tract.
