Multiple receive coils are needed for simultaneous
multislice (SMS) imaging, resulting in large raw data
storage requirements and long computation times for a
typical SMS fMRI scan. In this abstract, we compare and
evaluate the activation performance of varying levels of
coil compression on both SMS and conventional fMRI
scans. We use an efficient concentric ring trajectory
that has the susceptibility signal recovery benefit of
spiral-in imaging, and also facilitates the use of an
SMS GRAPPA reconstruction. GRAPPA and SENSE SMS
reconstruction results are compared with each other and
with those of a conventional scan.
