Angular double-pulsed-field gradient (d-PFG) MRI has been suggested as an alternative for studying microstructure in the brain. It has been shown that angular d-PFG MR experiments performed with long tms are able to distinguish between compartments with different eccentricities. Here, we study the effects of different experimental parameters on the obtained apparent eccentricity (aE) and residual phase maps of an ex-vivo rat brain obtained from angular d-PFG MRI collected with finite tms.
