Robust image quality is critical for reliable detection and evaluation of myocardial oxygenation changes with bSSFP BOLD imaging. This work evaluates the utility of 2D first-order motion compensation scheme to minimize flow/motion artifacts in cardiac phase-resolved bSSFP BOLD imaging using canines. Results show that compared to non-flow compensated bSSFP BOLD method, the proposed approach permits the evaluation of BOLD changes originating from coronary stenosis throughout the cardiac cycle.
