摘要
随着代谢显像的不断发展,放射性标记氨基酸引起临床更多关注。弄清氨基酸代谢基础和标记氨基酸在肿瘤中的作用更显必要。目前临床最常用的氨基酸显像剂如11C-蛋氨酸、11C-酪氨酸和123I-碘代甲基酪氨酸等,与18F-FDGPET相比很少受炎症影响,对脑部肿瘤显像准确性更好,对其他类型肿瘤也显示出更多的临床意义。
As the applications of metabolic imaging are expanding,radiolabeled amino acids has gained increased clinical interest.It is necessary to understand the basic aspects of amino acid metabolism and radiolabeled;and finally describe in the tumors.Have been most used clinically,such as,11 C-methionine,11 C-tyrosine and 123 I-iodomethyltyrosine.And the theoretic and clinical back-ground of amino acid imaging is clear and is fit for clinical applications.Contrasting with the 18 F-FDG PET suggested that is less troubled by interfering uptake in inflammatory tissues.There is a more accuracy in the brain tumors specially.In the other tumor types has been shown sufficiently.
