C-spine imaging is demanding due to artifacts from CSF flow, patient’s swallowing etc., especially in FSE sequence with inversion recovery. By increasing the excitation thickness in FSE sequence, two concomitant saturation bands are realized at both sides of each image slice, which suppress the moving CSF. Furthermore, a snapshot k-space ordering is proposed to further improve the stability of c-spine imaging against irregular flow of CSF and patient’s bulk motion.
