Slice selection and location of ROI for flow measurements in the coronary sinus. a-c Slice selection for acquisition of phase-contrast cine images of the coronary sinus. d, e Location of region of interest (ROI) for blood flow measurements and phase-offset correction. f Representative blood flow in the coronary sinus. Coronary sinus blood flow (CSBF)Â typically peaks twice during the systolic and diastolic phases. ROI, region of interest; ATP, adenosine triphosphate
