Diffusion MRI and Q-Space Diffusion MRI: From Cerebral Ischemia to Multiple Sclerosis and Beyond

Magnetic Resonance Imaging (MRI) is currently the most important imaging modality of the central nervous system (CNS) (Stark and Bradley Jr. 1999, Young 2000). The main reasons for that is the non-invasiveness of the method, the many physical parameters that can be used to obtain such MR images, the safeness of the technique and the fact that morphological information can be coupled with biochemical information using magnetic resonance spectroscopy (MRS).
