AbstractThis study aimed to employ in vivo multi-modal MR imaging to understand the radiation-induced brain damage in rats in correlation to histopathological changes at 12 months after radiation treatment. Results showed a loss in contrast in the ipsilateral corpus callosum and external capsule in T2WI, with a corresponding hyperintensity in trace map. The fractional anisotropy has also dropped in the fimbria of the hippocampus, suggestive of degeneration in this white matter structure; Significant increase in Cho:Cr and Lac:Cr ratios, and a marginally significant elevation in Glu:Cr ratio were observed at the site of radiation, whereas colocalization was found between manganese-enhanced MRI pattern and immunostaining for GFAP, MnSOD and GS, likely due to their Mn-dependent upregulation against oxidative stress and glutamate excitotoxicity.
