B0 mapping was performed with a circularly polarized pulse and with a non-selective universal parallel transmit (pTx) pulse. The pTx pulse showed improved homogeneity, which resulted in different B0 values, mainly present at tissue interfaces. Based on the two resulting B0 maps, patient specific B0 shimming was performed. Further, based on the two shimmed B0 maps, individually optimized pTx excitation and inversion pulses were designed for use in a 3D MPRAGE sequence. The pTx inversion pulse based on the B0 map, which itself used universal pTx pulse, achieved a reduction of B0 related artifacts in the frontal sinus region.
