DTI in Psychiatry

  • Chapter
Diffusion Tensor Imaging

Abstract

Recent advances in biological psychiatry promise to improve our understanding and treatment of mental illness through the development of objective, quantitative biomarkers. Furthermore, psychiatric disorders are increasingly conceptualized in terms of aberrant connectivity, where both brain structure and function are impaired. Diffusion MRI (including diffusion tensor imaging, DTI) bridges these two concepts by providing unparalleled insight into white matter microstructure in vivo, and hence the potential to identify useful biomarkers. However, the application of DTI in psychiatry is far from trivial owing to special challenges inherent to defining psychopathology, the practical issues associated with scanning patients and the lack of sensitivity and specificity of DTI measures. This chapter reviews the present and future role of DTI in psychiatry and provides a detailed overview of the practical issues that should be considered when designing and carrying out a DTI study that includes patients with psychiatric disorders.
