"Small-tip fast recovery" (STFR) is a recently-proposed steady-state imaging sequence that is a potential alternative to balanced SSFP. STFR relies on a tailored "tip-up" pulse to produce similar image contrast as bSSFP but with reduced banding artifacts. We evaluate the use of this new sequence for functional MRI using Monte Carlo Bloch simulations, and fMRI observations in visual cortex. Our results indicate that STFR can produce enhanced functional contrast compared to passband bSSFP.
