Axon size is an important parameter which affects conduction velocity in neuronal tissues. Recently angular d-PFG MR experiments were used to obtain microstructural information in different neuronal tissues. Since in many cases the ground truth of the studied samples is not known a priori, other and we have used microcapillaries phantoms of different complexity to challenge the microstructural information that can be obtained by modeling the signal in different NMR experiments. In the present study, we tried to evaluate simultaneously the size and direction of such systems from angular d-PFG NMR experiments.
