The invention relates to a class of positron imaging agents, in particular to fast-imaging necrotic myocardial imaging agents, preparation methods and applications thereof. Compared with the reported necrosis-affinity imaging agents, this type of imaging agent can clearly display necrotic myocardium as early as 15 minutes. By directly imaging the necrotic myocardium, the prognosis of myocardial infarction patients and the early diagnosis of other necrosis-related diseases can be carried out. |
