(A) PET perfusion images reveal a large, moderate to severe, reversible, myocardial perfusion defect in the LAD coronary artery vascular territory. (B) The calcium score was zero. (C) Myocardial blood flow analysis revealed reduced peak stress blood flow in the LAD territory but preserved global myocardial flow reserve. (D) Invasive angiographic images reveal severe stenosis in the proximal LAD that was (E) treated successfully with a drug-eluting stent. PET: positron emission tomography; LAD: left anterior descending artery.
