Abstract
This work explains the basic principles of diffusion weighted and diffusion tensor magnetic resonance imaging (MRI) methods. Both theoretical and experimental aspects are included. Scalar measures derived from diffusion tensors including new anisotropy measures in terms of entropy are presented. Fiber-tract mapping problem is discussed. Limitations of diffusion tensor MRI are included. Directional coherence tensor formalism to smooth the diffusion tensor data is presented. A brief discussion of new approaches to diffusion imaging, such as diffusion spectrum imaging and high angular resolution diffusion imaging, are also discussed. Results from diffusion weighted and diffusion tensor imaging are presented from excised rat spinal cord and brain images acquired at 17.6T.
