Phase-contrast cine cardiovascular magnetic resonance of the coronary sinus. (A) Axial image of the coronary sinus acquired by steady state free precession (white solid line). (B) Magnitude image of coronary sinus (white arrow). (C) Phase difference image of coronary sinus. Blood flow in the coronary sinus appears as a low signal intensity area in (C), (black arrow). CMR, cardiovascular magnetic resonance.
