Positron emission tomography has grown rapidly from a little-understood research tool into an exciting noninvasive method for the clinician to evaluate myocardial perfusion, metabolism, and cell-membrane function. There are three radionuclides that are currently being used widely in cardiac positron emission tomography. These are nitrogen-13 ammonia, rubidium-82, and fluorine-18 fluordeoxyglucose. Nitrogen-13 ammonia and rubidium-82 are used to assess the severity and location of coronary artery disease, while fluorine-18 fluordeoxyglucose can identify impaired but viable myocardium, thus aiding in the subsequent management of these patients.
正电子发射断层扫描已从一种鲜为人知的研究工具迅速发展成为一种令临床医生兴奋的非侵入性方法，用于评估心肌灌注、代谢和细胞膜功能。目前有三种放射性核素广泛应用于心脏正电子发射断层扫描。它们是氮-13氨、铷-82和氟-18氟脱氧葡萄糖。氮-13氨和铷-82用于评估冠状动脉疾病的严重程度和位置，而氟-18氟脱氧葡萄糖可以识别受损但仍存活的心肌，从而有助于对这些患者进行后续治疗。
