The visible vascular fraction f was statistically different for the three directions both at rest and with adenosine infusion. The flow velocity index D* was not statistically different among the three directions. The ADC value was the highest in the circumferential direction under all three physiologic conditions. Upon adenosine infusion there was a statistically significant increase of 25% in f in all three directions, with no discernable differences among them. The value D* also increased by 15% in all three directions.
