Diffusion tensor imaging (DTI) in combination with tract-based spatial statistics (TBSS) analysis provides valuable anatomical information about changes in brain areas contributing to epileptogenic process. Lateral thalamic nuclei are one of the areas highlighted in TBSS showing increased FA 6 months after status epilepticus in rats. The present work is focused to characterize the interrelationship of histopathological changes and ex vivo DTI in combination with TBSS analysis using several histological stainings and polarized light microscopy.
