The phase accumulation that spins experience during a MR sequence is closely linked to the microstructure within the voxel, and basically produces changes in T2* or T2. The present abstract demonstrates how the static bSSFP signal profile is modified by the influence of local susceptibility differences produce by the underlying local-frequency distribution and diffusion effects related to white matter and gray matter at 9.4T. We apply an analytical presentation of the diffusion-modified frequency distribution, previously only used for gradient and spin echoes, to bSSFP and we prove the applicability of this theory to bSSFP by Monte Carlo simulations and measurements.
