Diffusion tensor imaging (DTI) regional analyses and fractional anisotropy (FA) graphs quantify prevention of loss of microstructural integrity. (A) Diagram of DTI regions of interest (purple – striatum, yellow – corpus callosum, pink – external capsule white matter (ECWM), green – thalamus, and maroon – hippocampus). (B) Reduction of FA in the ECWM of vehicle-treated CAM-IVH rats is prevented in CAM-IVH rats with neonatal EPO+MLT treatment. (C) Similarly, reduction of FA in the central corpus callosum of vehicle-treated CAM-IVH rats is prevented by EPO+MLT treatment. (D) FA in the hippocampus is also decreased in vehicle-treated CAM-IVH rats compared to shams, and EPO+MLT treatment mitigates the damage. (E) Likewise, FA in the striatum is reduced in vehicle-treated CAM-IVH rats, and prevented in EPO+MLT-treated CAM-IVH rats. (F) FA in the thalamus is also lower in vehicle-treated CAM-IVH rats compared to shams, and normalizes with EPO+MLT treatment (all comparisons are two-way ANOVA with Bonferroni’s correction, p < 0.05, ∗∗p ≤ 0.01, ∗∗∗p ≤ 0.001).
