N2  - Cardiac phase-resolved Blood-Oxygen-Level-Dependent (CP-BOLD) MRI is a new approach for detecting ischemia at rest. Currently disease assessment relies on segmental analysis and uses only a few images in the phase-resolved acquisition. It is expected that using all phases can permit pixel-level characterization of CP-BOLD MRI. In this study, state-of-the-art image registration techniques are evaluated on cardiac BOLD MRI data for the first time. The results show that cardiac phase-dependent variations in myocardial BOLD contrast in CP-BOLD images creates a statistically significant decrease in the accuracy compared to standard Cine MR images acquired under conditions of health and myocardial ischemia.
