Average SNR per excitation for the closed and perfused systems with a high driving exchange rate. The average SNR maximizes at higher excitation angles and longer TRs. Additionally, the SNR of the perfused system has a limited dependence on TR for higher excitation angles. Average SNR plots are similar for lower driving exchange (data not shown).
