One version of a new ultrafast gradient-echo-based 3D imaging technique using spatiotemporal encoding (RASE-II) is proposed which provides constant TE across all spins. RASE-II maintains most of appealing features of other spin-echo-based SPEN imaging methods such as no Nyquist ghosting and high tolerance to field inhomogeneities. RASE-II also has less sensitivity not only to SAR and B1-inhomogeneity effects because of low flip angles, but also to T2* signal modulation due to constant TE. As a promising tool for fMRI, RASE-II shows significant improvement of tSNR over GE-EPI. Its performance is demonstrated by lemon and in-vivo rat brain imaging at 9.4T.
