摘要
心脏PET/CT可获得高质量的心肌灌注图像,并能定量心肌血流量,无创获取绝对心肌血流量(MBF)和冠状动脉血流储备(CFR),能客观、早期诊断和评估冠状动脉循环功能,用于缺血性心脏病(IHD)和特殊人群心肌缺血的早期诊断、危险度分层和预后评估.该文主要综述PET/CT定量测定MBF及CFR的原理、特点及其应用进展.
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.
