基于较高的靶本比(TBR),靶向成纤维细胞激活蛋白(FAP)新型显像剂在多种肿瘤中表现出较好的显像效果。近年来,随着研究的深入,FAP的抑制剂(FAPI)在肿瘤显像与治疗中显示出了巨大的应用前景,其可以作为主流代谢显像剂氟-18标记氟代脱氧葡萄糖(18F-FDG)的补充,为未来肿瘤代谢和肿瘤间质可视化的更高效结合提供了可能,有助于更准确地指导临床诊断与治疗。文章主要综述了FAP新型显像剂在多种肿瘤中的应用情况,将其与现有的放射诊断手段进行了比较,重点总结了特异性靶向FAPI的示踪剂在肿瘤及非特异性组织中的临床应用进展及未来潜力。

Based on the high target-to-background ratio(TBR),new imaging agents targeting fibroblast activation protein(FAP)have shown better imaging effects in a variety of tumors. In recent years,with in-depth research,FAP inhibitor(FAPI)has shown great application prospects in tumor imaging and treatment. It can be used as a supplement to the mainstream metabolic imaging agent 18F-labeled fluorodeoxyglucose(18F-FDG),which provides the possibility of more efficient combination of tumor metabolism and tumor stroma visualization in the future. It is helpful to guide clinical diagnosis and treatment more accurately. This article mainly reviews the application of new FAP imaging agents in various tumors,compares them with existing radiological diagnostic methods,and summarizes the clinical application progress and future potential of tracers specifically targeting FAPI in tumors and non-specific tissues.
