Technical advances in magnetic resonance imaging (MRI) have lead to clinical and scientific applications with higher spatial and temporal resolution. One area of interest is in neuroscience and neuropathology studies towards revealing the ambiguities of human brain function and mental brain disorders. As more challenging patient populations are imaged and more advanced experiments are designed, there is an increasing demand for more accurate localization of brain function and structure. Localization of functional information and fusion of magnetic resonance images has been addressed through image registration techniques. Accurate rigid and affine registration techniques are now part of the standard brain image processing toolkits, which aim at correcting the effect of head motion and repositioning into a sub-voxel range. However, local spatial distortions may cause typical localization errors of up to 10 millimeters in magnetic resonance images acquired by Echo-Planar Imaging (EPI). This compromises the accuracy of localization and registration in functional MRI, Diffusion Tensor Imaging and Arterial Spin Labeling. Such spatial distortions are mainly caused by field inhomogeneity and susceptibility artifacts and cannot be compensated by rigid and affine registration techniques. Therefore, the main thrust of this dissertation has been the deployment of non-rigid registration for the correction of local spatial distortions in EPI. As a main challenge, quantitative in-vivo validation criteria have been devised to support the routine use of the developed techniques as part of a toolkit named NPTK, or Neuroimage Processing ToolKit. The outcome of this research makes up the core component of NPTK for enhanced localization. The technical developments on the optimization aspects of information similarity measures carried out as part of this research is generally applicable to high-dimensional optimization problems including non-rigid registration, information theoretic learning, pattern classification, and bioinformatics.

This book provides an overview of the practical aspects of diffusion tensor imaging (DTI), from understanding the basis of the technique through selection of the right protocols, trouble-shooting data quality, and analyzing DTI data optimally. DTI is a non-invasive magnetic resonance imaging (MRI) technique for visualizing and quantifying tissue microstructure based on diffusion. The book discusses the theoretical background underlying DTI and advanced techniques based on higher-order models and multi-shell diffusion imaging. It covers the practical implementation of DTI; derivation of information from DTI data; and a range of clinical applications, including neurosurgical planning and the assessment of brain tumors. Its practical utility is enhanced by decision schemes and a fully annotated DTI brain atlas, including color fractional anisotropy maps and 3D tractography reconstructions of major white matter fiber bundles. Featuring contributions from leading specialists in the field of DTI, Diffusion Tensor Imaging: A Practical Handbook is a valuable resource for radiologists, neuroradiologists, MRI technicians and clinicians.

This richly illustrated book, now in an updated and extended third edition, systematically covers the use of diffusion-weighted (DW) MR imaging in all major areas of neuroradiology, including imaging of the head and neck and the spine as well as the brain. The authors guide the reader from the basic principles of DW imaging through to the use of cutting-edge diffusion sequences such as diffusion tensor (DTI) and kurtosis (DKI), fiber tractography, high b value, intravoxel incoherent motion (IVIM), neurite orientation dispersion and density imaging (NODDI), and oscillating gradient spin echo (OGSE). Pathology, pathophysiology, and patient management and treatment are all thoroughly discussed. Since the early descriptions by LeBihan and colleagues of the ability to image and measure the micromovement of water molecules in the brain, diffusion imaging and its derivatives have contributed ever more significantly to the evaluation of multiple disease processes. In comprehensively describing the state of the art in the field, this book will be of high value not only for those who deal routinely with neuro-MR imaging but also for readers who wish to establish a sound basis for understanding diffusion images in the hope of extending these principles into more exotic areas of neuroimaging.

The concepts behind diffusion tensor imaging (DTI) are commonly difficult to grasp, even for magnetic resonance physicists. To make matters worse, a many more complex higher-order methods have been proposed over the last few years to overcome the now well-known deficiencies of DTI. In Introduction to Diffusion Tensor Imaging: And Higher Order Models, these concepts are explained through extensive use of illustrations rather than equations to help readers gain a more intuitive understanding of the inner workings of these techniques. Emphasis is placed on the interpretation of DTI images and tractography results, the design of experiments, and the types of application studies that can be undertaken. Diffusion MRI is a very active field of research, and theories and techniques are constantly evolving. To make sense of this constantly shifting landscape, there is a need for a textbook that explains the concepts behind how these techniques work in a way that is easy and intuitive to understand—Introduction to Diffusion Tensor Imaging fills this gap. Extensive use of illustrations to explain the concepts of diffusion tensor imaging and related methods Easy to understand, even without a background in physics Includes sections on image interpretation, experimental design, and applications Up-to-date information on more recent higher-order models, which are increasingly being used for clinical applications
