Simulations and experiments exploring the steady state signal amplitude dependency on the spoiler gradient in unbalanced gradient echo sequences and RF-spoiled gradient echo sequences are shown. Additionally, for these sequences and also under consideration of diffusion, signal evolution over the sequence repetition cycles is simulated for hyperpolarized nuclei in gas and liquid phase.
