 Abstract: EPI, the “work horse” of fMRI, is prone to artifacts, induced by B0 inhomogeneities. Therefore, sophisticated B0 shimming techniques are required. A promising, but technically demanding approach for B0 shimming is dynamic shim updating (DSU). The application of DSU to fMRI is, however, only feasible, if an accurate pre-emphasis calibration for eddy current correction (ECC) is implemented. This work presents the first report of resting-state fMRI data, acquired with a 3rd-order dynamically updated B0 shim along with a dynamic F0 determination.
