Simultaneous Multi slice acceleration (SMS) EPI
technique provides a new tool for measuring the DSC-MR
and BOLD signal with higher spatial and/or temporal
resolution. In this study, we applied an iterative
algorithm to extract the global pattern by averaging the
time series of each voxel after re-alignment based on
its time-shift. In addition, by using SMS EPI sequence
for rs-fMRI data acquisition, higher temporal resolution
(TR = 1000 ms) and higher spatial resolution can be
achieved to provide more accurate results.
