Abstract
Cardiac PET/CT can not only obtain high quality myocardial perfusion images, but also non-invasively quantify myocardial blood flow (MBF) to obtain absolute MBF and coronary flow reserve (CFR), which can objectively diagnose and evaluate coronary arterial circulation function in the early phase. Cardiac PET/CT can be used for early diagnosis of myocardial ischemia, risk stratification and prognosis evaluation in patients with ischemic heart disease (IHD) and special group. The principle, characteristics and application progress of MBF and CFR quantitation by PET/CT are reviewed in this article. Key words: Myocardial ischemia; Fractional flow reserve, myocardial; Myocardial perfusion imaging; Positron-emission tomography; Tomography, X-ray computed; Trend
