Positron emission tomography (PET) uniquely permits the noninvasive study and quantification of regional rates of blood flow and metabolism in human myocardium. In myocardial ischemia, PET identifies the presence and extent of viability in dysfunctional myocardium and distinguishes it from irreversible ischemic injury and scar tissue formation. Because metabolic markers have proved more accurate and reliable for identifying viability than conventional diagnostic approaches, PET has become increasingly useful for characterizing the severity and extent of an ischemic injury and for assigning patients with acute or chronic coronary artery disease to the most efficacious treatment.
正电子发射断层扫描（PET）独特地允许对人类心肌的区域血流和代谢速率进行无创研究和量化。在心肌缺血中，PET可识别功能失调心肌中存活心肌的存在及其范围，并将其与不可逆缺血损伤和瘢痕组织形成区分开来。由于代谢标志物已被证明在识别存活心肌方面比传统诊断方法更准确、更可靠，PET在表征缺血损伤的严重程度和范围以及将急性或慢性冠状动脉疾病患者分配至最有效的治疗方案方面变得越来越有用。
