Background As for the patients with coronary arteriosclerosis, the presence of ischemic myocardial survival is significant for the treatment and prognosis. Gated 13N-NH3 and 18SF-FDG PET/CT imaging provides myocardial perfusion, metabolism and cardiac function which can valuate myocardial viability accurately and noninvasively. Methods Four pigs were subjected to bilateral internal mammary artery Y-bypass operation in operating room. The pigs under the anesthetized state were sent to PET center when the operation finished. Then 13N-NH3 gated-PET/CT and 18F-FDG gated-PET/CT were performed. Results The myocardial perfusion and myocardial metabolism is well-distributed of left ventricular wall. The motion of the wall was normal. The ejection function was greater than 50%. Conclusion Gated-PET/CT can be used for noninvasive evaluation of myocardial perfusion, myocardial metabolism and left ventricle function.
