The book "Diffusion Tensor Imaging" offers a comprehensive introduction to the practical aspects of diffusion tensor imaging (DTI). It covers the fundamentals of the technique and guides readers through the selection of appropriate protocols, optimization of data quality, and analysis of DTI data. DTI is a non-invasive magnetic resonance imaging technique that allows for the visualization and quantification of the microenvironment of tissues based on diffusion. The work highlights the theoretical foundations of DTI as well as advanced techniques based on higher-order models and multi-shell diffusion imaging. Additionally, it addresses the practical implementation of DTI, the derivation of information from DTI data, and various clinical applications, such as the planning of neurosurgical procedures and the assessment of brain tumors. The practical utility of the book is enhanced by decision diagrams and a fully annotated DTI brain atlas, including color-coded fractional anisotropy maps and 3D tractographies of the major white matter fiber bundles. With contributions from leading specialists in the field of DTI, this handbook is a valuable resource for radiologists, neuroradiologists, MRI technicians, and clinicians.
