Incidental congenital coronary artery vascular fistulas in adults: Evaluation with adenosine-13N-ammonia PET-CT

Figure 11 Positron emission tomography computed tomography scanning demonstrating normal findings on the rest ¹³N-ammonia polar map (left panel) and normal perfusion on adenosine ¹³N-ammonia polar map (right panel). Myocardial perfusion was assessed at rest and during vasodilator pharmacological stress induced by adenosine, using 400 MBq of ¹³N-ammonia as the perfusion radiotracer.
