Comparisons of quantitative perfusion rates. Note the return to baseline perfusion values when the infusion of Adenosine was stopped. The increase in perfusion is comparable after each dose, and is statistically significant compared to the baseline. On the other hand, administration of L-NAME results in significant reduction in perfusion compared to baseline. Following the second administration, there is further significant reduction in perfusion. No significance difference was observed between the two baseline, as well as Adenosine scans.
* indicates significant difference (p < 0.05) comparing to the corresponding baseline scans.
+ indicates significant difference (p < 0.05) comparing to the first L-NAME scan
