Estimated marginal means corrected for postconceptional age of parallel diffusion, E₁ (A); perpendicular diffusion, E₂₃ (B); ADC (C); and FA (D) of the postsurgical (postsurg) and presurgical (presurg) groups. DTI in the genu of the CC and splenium of the CC in the postsurg group reveals higher E₂₃, higher ADC, and lower FA than those in the presurg group. The E₁ is higher in the genu of the CC and lower in the splenium of the CC of the postsurg compared with the presurg group, but these differences are significant.
