Navigator Echo Collection for Sliding Interleaved Cylinder Acquisition

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.
