A Unique Analytical Solution of the White Matter Standard Model using Linear and Planar Encodings.

Valerij G. Kiselev, Bibek Dhital, Marco Reisert

Diffusion-weighted magnetic resonance imaging in brain white matter probes tissue microstructure and allows for the estimation of compartmental diffusion parameters. Recently, it became apparent that traditional single-direction diffusion encodings are not fully sufficient to resolve the white matter compartmental diffusivities. Multiple diffusion encodings have been suggested to make the problem less ambiguous, however, it still remained unclear whether such protocols would completely solve the problem. Here, we constructively prove that a combination of linear and planar diffusion encodings is enough to determine the parameters of the three compartment white matter model.
