Epilepsy is a challenging disease for imaging due to heterogeneous, widespread and non-focal changes in the brain tissue. The present study diffusion tensor imaging (DTI) and tract-based spatial statistics (TBSS) analysis provides "anatomics" of the brain pathology during experimental epileptogenesis, revealing areas involved in the epileptogenic process in a kainic acid animal model. This technique has a great potential to serve as a robust screening method to guide tedious histological analysis aimed to reveal cellular alterations of neuronal pathways.
