Diffusion-weighted MRI is sensitive to biological tissue architecture on a micrometer scale. Determining whether it is possible to infer the specific mechanisms that underlie changes in DW-MRI could lead to new diffusion contrasts specific to particular brain white-matter degeneration processes. We have developed a renormalization group method in order to explore the effects of a large range of microparameters on apparent diffusion and have applied it to different kinds of biological tissue tessellations. Our approach takes the influence of disorder into the consideration and it allows quantitative investigation of the sensitivity of apparent diffusion to the variations of the dominant set of microparameters.
