Balanced SSFP (bSSFP) sequences with additional preparatory schemes like diffusion weighting, T2 weighting and selective flow suppression are extremely sensitive to changing eddy currents patterns. In this work, we demonstrate a mechanism to minimize eddy currents in bSSFP sequences with preparatory schemes without any change in the bSSFP image contrast. This is achieved by generating a continuous yet dynamically switching gradient pattern along the entire PE axis. This preferentially diminishes deviations in PE gradient amplitude near the centre of k-space and reduces the eddy current artifact intensity.
