Measuring micro-architectural features involving cell body morphologies is emerging as a frontier of diffusion MRI. This work aimed to map the apparent soma size and density and neurite density via the SANDI methodology in the mouse brain in-vivo at 9.4T. Our results show consistent parameters values between N=3 animals in both gray and white matter ROIs. Moreover, we have also compared the effects of using different number of shells and maximum b-values in the SANDI analysis. Our work augurs well for future investigations in animal models of plasticity and disease.
