Significant off-resonance exists in the pulmonary veins (PV) due to their close proximity to the lungs. In this study, we report that PV blood exhibits a mean off-resonance of 58~113Hz which remains relatively constant through the cardiac cycle. We use this frequency shift to enhance the PV blood signal in SSFP imaging.
