An Introduction to Visualization of Diffusion Tensor Imaging and its Applications

Water diffusion is anisotropic in organized tissues such as white matterand muscle. Diffusion tensor imaging (DTI), a non-invasive MR technique, measureswater self-diffusion rates and thus gives an indication of the underlying tissuemicrostructure. The diffusion rate is often expressed by a second-order tensor. InsightfulDTI visualization is challenging because of the multivariate nature and thecomplex spatial relationships in a diffusion tensor field. This chapter surveys thedifferent visualization techniques that have been developed for DTI and comparestheir main characteristics and drawbacks. We also discuss some of the many biomedicalapplications in which DTI helps extend our understanding or improve clinicalprocedures. We conclude with an overview of open problems and research directions

Multi-dimensional computed cardiac visualization

During the past decade, coronary radiology has undergone rapid development. This second edition of the only available monograph on the subject places special emphasis on the role of non-invasive techniques, which can supply information on the condition of the coronary arteries within one simple and short examination. The modalities considered in detail include CT angiography with multidetector and dual-source tomography, 2D and 3D visualization techniques, and MR coronary angiography. Invasive procedures are not neglected, however, and a separate section includes chapters on conventional catheterization, quantitative angiography, and intravascular and quantitative ultrasound. In addition, a section devoted to coronary calcification clearly explains its development and the use of modern techniques in its visualization and quantification. The informative text is supported by a large number of high-quality color images of the coronary and cardiac anatomy
