We optimized a spiral sequence for dual-echo cardiac gating applied to cervical spine fMRI. Dual-echo obviates dependency on variable initial longitudinal magnetization that would, otherwise, require T1 correction. Spiral acquisition allows short echo time and readout duration which maximizes SNR and BOLD contrast. Our technique improves tSNR and fMRI activation when compared with ungated sequence.
