Small tip fast recovery (STFR) imaging has been proposed
recently as a potential alternative to balanced steady
state free precession (bSSFP). STFR relies on a tailored
tip-up RF pulse to achieve comparable signal level and
image contrast as bSSFP, but with reduced banding
artifacts. Previous STFR implementations used 2D or 3D
pulses spatially tailored to the accumulated phase
calculated from a B0 field map. Here we propose to
replace the spatially tailored pulse with a spectrally
tailored pulse, which can be precomputed to a target
frequency range. We show that this spectral-STFR
sequence has reduced banding artifacts compared to bSSFP.
