Application progress in quantitative determination of myocardial blood flow and coronary flow re-serve by PET/CT / 中华核医学与分子影像杂志

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 prog-nosis evaluation in patients with ischemic heart disease ( IHD) and special group. The principle, character-istics and application progress of MBF and CFR quantitation by PET/CT are reviewed in this article.
