A method for real time phase contrast imaging with highly undersampled FLASH and regularized nonlinear inversion reconstruction was developed. High temporal resolution of 42.5 ms per phase contrast map avoids the temporal and/or spatial averaging effect common in Cine Phase Contrast Imaging. Variations of flow parameters for through plane flow of the ascending and descending aorta with respect to individual heart cycles and respiration were analyzed.
