Abstract: We investigate the possibility of using longer multi-shot spiral readouts to accelerate balanced steady-state free precession (bSSFP) at ultra-high field (UHF) for functional imaging. The reconstruction is performed with the full signal model accounting for spatial B0 inhomogeneity and gradient imperfections. We present the activation maps from flickering checkerboard stimulus experiment and discuss challenges of spiral bSSFP at UHF.
