First-pass myocardial perfusion imaging is a powerful
method for characterizing ischemic heart disease.
Standard methods use saturation preparation and an ECG
trigger. A new ungated acquisition with no saturation
preparation could be used to acquire steady-state
spoiled gradient echo (SPGR) images. Here, readouts from
multiple (three) slices are interleaved in order to keep
the multiple slices at steady-state and increase the
effective TR. Simulations, phantoms, and human data are
used to compare the interleaved acquisition to a
conventional saturation recovery sequence both in radial
and Cartesian trajectories.
