FIGURE 7. Rest-stress myocardial perfusion PET/CT images in patient with severe angina demonstrate small region of moderate reversibility in middle and basal inferolateral walls. Gated study demonstrated significant decrease in LVEF during peak stress. Catheter coronary angiography demonstrated left dominant anatomy and severe left main CAD (bottom panel). Patient underwent coronary artery bypass surgery. LVEDV = left ventricular end-diastolic volume; LVESV = left ventricular end-systolic volume; LM = left main coronary artery.
