Diffusion Tensor Imaging (DTI) techniques have allowed the unprecedented non-invasive exploration of brain microstructure integrity in a wide variety brain disorders. In particular, their application to psychiatric disorders has highlighted white matters important role in these disorders pathophysiology. However, DTI metrics are limited by their lack of specificity to the underlying nature of white matter alterations and by relatively reduced sensitivity to gray matter changes. Advanced Diffusion Imaging methods are currently proposed to address some of these limitations. In this talk, I will introduce some of these new methods and will present their application to two psychiatric disorders, autism and schizophrenia. Our data suggest that whereas white and gray matter microstructure appears to be altered in both of these disorders, the underlying pathophysiology appears to differ. These findings and their relevance to the field will be discussed.
