Studies have shown that bSSFP-based myocardial Blood-oxygen-Level-Dependent (BOLD) contrast is directly dependent on repetition time (TR). However, in the presence of field inhomogeneities, image artifacts scale with TR. Although the multiple acquisitions technique has been used to mitigate against banding artifacts, its applicability in cardiac imaging has not been investigated. In this work, we demonstrate that an optimized dual acquisition strategy combined with flow compensation may be a viable means for achieving robust image quality for myocardial cine BOLD MRI at 3T.
