TL;DR: Here, high b value q-space diffusion imaging is performed on the brains of healthy subjects and multiple sclerosis patients.
Abstract: holds under the long time scale limit (long diffusion time relative to the cell dimensions) and the short gradient pulse approximation (3-4). The application of this method for the human brain is difficult since the gradient system of clinical scanners has much lower amplitude than animal scanners. This implies that long gradient pulses (that violate the short gradient pulse approximation) should be used (4). Here we performed high b value q-space diffusion imaging on the brains of healthy subjects and multiple sclerosis (MS) patients.

TL;DR: 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).
