Figure 1From: Assessment of global myocardial perfusion reserve using cardiovascular magnetic resonance of coronary sinus flow at 3 TeslaRegadenoson CMR stress protocol. Stress perfusion protocol showing timing of administration of regadenoson and aminophylline. Coronary sinus flow was measured using phase-contrast imaging at three time-points (pre-stress, peak stress, and post stress). LGE = late gadolinium enhancement.Back to article page
