A sliding interleaved cylinder (SLINCY) acquisition
employs a 3D concentric cylinders trajectory as the
readout instead of a 3DFT sequence. Previously, SLINCY
was incorporated into a non-contrast-enhanced
magnetization-prepared 3D SSFP sequence to improve
artery-vein contrast in the lower extremities. However,
one of remaining issues for this approach is to suppress
the long-T1 fluids, which can otherwise hamper the
depiction of arterial blood in SSFP images. In this
work, we exploited the thin-slab-scan nature of SLINCY
to efficiently add inversion-recovery (IR) to suppress
the fluids. We demonstrated that the proposed IR schemes
are feasible for SLINCY, which successfully suppressed
the fluids.
