The
sensitivity to physiological noises of the reconstructed BOLD MR images is
altered by the employed parallel imaging strategies. In this study, we mapped
and compared the physiological noise sensitivity of BOLD fMRI data acquired with
and without employing parallel imaging at two different spatial resolutions.
Using higher spatial resolution reduces the signal strength and the relative
sensitivity to physiological noise. This can be of SNR advantage particularly
for time series fMRI data acquired at higher magnetic field.
