Synopsis
GRE- or SE-based line-scanning fMRI methods can characterize dynamic fMRI signals with high spatial and temporal resolution. Here, we present a combination of both using a 1D GRASE sequence with perpendicular excitation and refocusing slices. We applied the sequence in-vivo at 3T and analyzed slice pofiles and tSNR.
