Rest and stress MBF maps from two representative healthy swine. Low MBF was observed in the inferior and inferoseptal segments at rest (arrows) but was elevated during vasodilation (arrow heads). Global MBF ± physiologic noise (PN) at rest and stress are (top row) 0.87 ± 0.04 and 1.38 ± 0.02 ml/g/min and (bottom row) 0.78 ± 0.16 and 1.39 ± 0.07 ml/g/min, respectively. Inferoseptal MBF ± PN at rest are (top) 0.03 ± 0.17 and (bottom) 0.13 ± 0.25 ml/g/min. These were elevated to 0.62 ± 0.09 and 1.31 ± 0.35 ml/g/min during vasodilation, respectively
