In a pig model of chronic myocardial infarction, infarct size can be measured by cardiac PET/CT and delayed CT enhancement. A low-dose, prospectively gated acquisition obtained as early as 10 min after contrast injection achieves measurements comparable to those of rest perfusion PET. The colored areas in these polar maps represent global defects after applying a threshold of 3.5 SDs above the mean of remote myocardium for CT.
