摘　　要：正电子发射断层显像/计算机断层成像(PET/CT)由于敏感度高、无创等优点,在心血管疾病的诊断中占据了重要的地位。不同正电子显像剂为提高检查的特异性和敏感度提高了保证。在心肌代谢疾病中,代谢底物的改变常发生在解剖结构之前,通过判断代谢方式的改变对预估心肌受损有重要意义,从而心肌对代谢底物的选择为正电子显像剂的设计提供了想法和思路。本文根据不同代谢途径将其分成氧代谢途径,糖代谢途径及脂肪酸代谢3类,并从不同核素及其适用的诊断方向等对其优缺点进行分类论述,以期在未来结合更多技术得到更加性能优良的代谢显像剂。Positron emission tomography/computed tomography(PET/CT),due to its sensitivity and noninvasiveness,has occupied an important role in the diagnosis of cardiovascular diseases.Different positron imaging agents are guaranteed to improve the specificity and sensitivity of the examination.In myocardial metabolic disease,the change of metabolic substrate often occurs before the anatomical structure,and it is important to estimate the myocardial damage by judging the change of metabolic way,so that the choice of metabolic substrate by myocardium provides ideas and ideas for the design of positron imaging agents.In this paper,we divided them into three categories,including oxygen metabolism pathway,glucose metabolism pathway and fatty acid metabolism according to different metabolic pathways,and its advantages and disadvantages are categorically discussed from different nuclides and their applicable diagnostic directions,with a view to combining more technologies in the future to obtain more performance metabolic imaging agents.
