Part A- Trace values for the white matter ROI for all imaging time points. A significant main effect of reduced diffusion is seen for IR-30 and IR-39 animals relative to sham rats. Part B- Fractional Anisotropy (FA) values, however, did not show any significant group differences and remained essentially the same across the imaging time points. In rats, it does not appear that an fWBI dose of 30 or 39Gy causes significantly measurable white matter breakdown as seen in adult survivors of childhood cancer. Error bars indicate the standard error of the mean (SEM).
