PET is a functional imaging method that can exploit various aspects of tumor biology to enable greater detection of prostate cancer than can be provided by morphologic imaging alone. Anti-1-amino-3-F-flurocyclobutane-1-carboxylic acid (F-fluciclovine) is a nonnaturally occurring amino acid PET radiotracer that was recently approved by the U.S. Food and Drug Administration for detection of suspected recurrent prostate cancer. The tumor-imaging features of this radiotracer mirror the upregulation of transmembrane amino acid transport that occurs in prostate cancer because of increased amino acid metabolism for energy and protein synthesis. This continuing medical education article provides an overview on F-fluciclovine PET diagnostic capabilities for primary and metastatic disease, including reviews of published comparisons to conventional imaging and other molecular imaging agents. Additionally, the imaging procedure and image interpretation are detailed, including physiologic and pathologic uptake patterns and pitfalls.
正电子发射断层扫描(PET)是一种功能成像方法,可利用肿瘤生物学的各个方面,比形态成像单独提供更能检测前列腺癌。1-氨基-3-氟环丁烷-1-羧酸(F-氟代赖氨酸)是非天然存在的氨基酸 PET 放射性示踪剂,最近被美国食品和药物管理局批准用于检测可疑的复发性前列腺癌。该放射性示踪剂的肿瘤成像特征反映了前列腺癌中转录上调的跨膜氨基酸转运,因为氨基酸代谢增加以提供能量和蛋白质合成。这篇继续医学教育文章概述了 F-氟代赖氨酸 PET 在原发性和转移性疾病中的诊断能力,包括对已发表的与常规成像和其他分子成像剂的比较的回顾。此外,详细介绍了成像程序和图像解释,包括生理和病理摄取模式和陷阱。
