Structural information of different nerve types from high b-value q-space diffusion MRS
Bar-Shir A, Cohen Y
High b-value q-space diffusion MR were claimed to provide structural information under certain experimental conditions. Here, we use this methodology to examine the mean displacement in optic and sciatic nerves as a function of the diffusion time. The mean displacements of the sciatic nerves (both components) were found to be significantly larger than in the optic nerves. The slow diffusing component of the optic nerves was found to be the most restricted one. The extracted sizes were found to be comparable with those observed by microscope images suggesting that high-b value q-space diffusion MR can be regarded as ""virtual histology"".
