Physiologic noise in BOLD acquisitions is problematic
for fMRI and connectivity analyses, and is an increasing
problem at higher field strengths. There is one existing
software package, PESTICA, that can obtain signals at 3T
with the same periodicity as parallel monitored pulse
and respiration signals and thus can be used in
physiologic corrections. PESTICA uses spatial priors
generated at 3T and we test PESTICA at 7T, finding
promising results.
