Background suppression is a recommended and frequently employed strategy to improve the perfusion-temporal-SNR (tSNR) of ASL. Since physiological signal fluctuations are known to be a major source of data corruption in functional MRI at higher magnetic field-strengths, it might also be expected that the benefits of BGS are even stronger at higher field-strengths. In this study, we evaluated and compared the importance of the introduction of BGS-pulses at 3T and 7T and show that, at higher magnetic field, BGS is even more crucial.
