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.
