We
recently introduced a novel ultrafast 3D gradient-echo-based
imaging technique using spatio-temporal encoding (SPEN) or quadratic-phase
encoding, which were dubbed RASE-I
and -II (Rapid Acquisition with Sequential Excitation). RASE has less sensitivity to field
inhomogeneities and susceptibility differences compared to conventional gradient-echo EPI (GE-EPI), sharing the
advantages of 3D imaging such as high signal-to-noise ratio and high spatial
resolution. In this study, we present promising results of RASE-II fMRI, i.e.,
better t-scores, tSNR than conventional 2D and 3D GE-EPI, on a 9.4-T animal
scanner.
