A novel method based on single-voxel-spectroscopy (PRESS) for the analysis and correction of eddy-current induced artefacts in spiral phase-contrast MRI is presented. It is demonstrated, that 0th and 1st order corrections result in residual background offsets of less than 0.5cm/s, inherently correcting for geometrical misalignments between flow acquisitions as well as 2nd order spatial phase offsets. The method does not require special hardware and can be applied as a pre-scan.
