摘要
近几年正电子发射计算机断层扫描(PET)作为分子影像学的代表,正逐渐走向临床,而PET 显像剂也相应发展,其目的就是为临床勾勒出肿瘤解剖形态之外的生物学特征。PET 显像剂种类很多,主要有代谢、乏氧、增生、凋亡、生长因子受体显像剂等。虽然各有优缺点,但相信随着进一步的研究和开发,PET 显像剂将最终会为临床提供可靠、清晰、准确的 PET 图像。
As a representative of molecular imaging,the clinical application of PET modality is in- creasing fast.At the same time,PET tracers are also developed for delineating the biological characters in clinical application,except for the anatomic form.There are many kinds of PET tracers,and the main cate- gories are as the following:metabolic,hypoxia,proliferation,apoptosis and growth factor receptor tracers.Al- though they have their own drawbacks and advantages,it is confident that,with further development and re- search,PET tracers could provide reliable,clear and precise PET images for clinical judgment in the long run.
