FIG 1.

A, The gestational age of the infants considered when evaluating the myelination of the PLIC. In the coronal T1-weighted image, the myelination of the PLIC was considered as age-appropriate for a near-term infant (35 weeks of gestation) and was scored as normal. B, The gestational age of the infants was considered when evaluating the peak of the NAA. In ¹H-MR spectroscopy (TE = 30 ms), the peak NAA was considered as age-appropriate for a near-term infant (35 weeks of gestation) and was scored as normal. C, The lesion that had involvement of both the WM and cortex was scored individually only for the principal area. In axial DWI, the diffusion restriction in the cortex and its location were scored as focal (1 lobe) and unilateral (score of 2). The WM involvement was scored individually as focal and unilateral (score of 2). D, The extension of signal abnormality (involving 1 lobe or >1 lobe) was scored on the basis of the primary area of injury. In axial ADC mapping, the diffusion restriction in the WM was scored as focal (score of 1) because only the frontal lobe was involved and the location was scored as bilateral (score of 2).
