Representative Examples of Cardiac quantitative susceptibility mapping (QSM) in Healthy Subjects. a Unsuccessful 2DBHQSM due to slice mis-registration (white arrows) attributable to inconsistent breath-hold positions, resulting in non-diagnostic QSM map. Corresponding 3DNAVQSM was successful, yielding physiologic differential oxygen saturation between the left ventricle (LV) and right ventricle (RV). b Successful 2DBHQSM and 3DNAVQSM, resulting in equivalent QSM maps
