In this simulation study, we aim to demonstrate the feasibility of improving non-contrast enhanced renal MRA by adding a cardiac gate with dynamically determined inversion times. The benefits of the proposal include higher contrast due to better background suppression and improved inflow enhancement, which may be clinically significant for delineating occluded vessels.
