Diffusion Tensor Imaging Versus Conventional MRI in Temporal Lobe Epilepsy: A Comparative Study of Diagnostic Performance

Abstract

Background: Conventional magnetic resonance imaging (MRI) may appear normal in a proportion of patients with temporal lobe epilepsy (TLE). Diffusion tensor imaging (DTI) provides quantitative measures of white matter microstructure and may reveal subtle changes not visible on routine MRI. This study compared DTI-derived diffusion metrics with standard MRI epilepsy protocols in patients with unilateral TLE to assess the extent and pattern of white matter alterations.
