First-pass myocardial perfusion imaging offers a
valuable method for characterizing the blood flow of the
myocardial tissue. Much of the work in myocardial
perfusion imaging has used saturation preparation and an
ECG trigger. An alternative approach is to use a spoiled
gradient echo (SPGR) steady-state acquisition that
acquires images rapidly enough so that ECG gating is not
needed. In 2D simultaneous multi-slice acquisition, we
utilize the CAIPI technology to achieve whole heart
coverage and combined that with interleaved slice
acquisition, which increases the effective TR. In this
study, we demonstrate that the ungated golden ratio
radial CAIPI with interleaved acquisition provides
reasonable CNR while providing whole heart coverage.
