A sliding interleaved cylinder acquisition has
previously been incorporated into a steady-state free
precession sequence to achieve improved artery-vein
contrast in the lower extremities. In this work, we
extended the sequence to acquire navigator echoes
without additional scan time to allow more flexibility
in selecting an RF excitation pulse. A set of in vivo
experiments on healthy volunteers demonstrated that the
proposed scheme allowed the use of a non-linear-phase RF
excitation pulse with a shorter TR and a sharper slab
profile, which improved the robustness of the sequence.
