The purpose of this article is to describe the large number of radiotracers being evaluated for prostate-specific membrane antigen (PSMA) PET, which is becoming a central tool in the staging of prostate cancer.
PSMA PET is a highly promising modality for the staging of prostate cancer because of its higher detection rate compared with that of conventional imaging. Both PET/CT and PET/MRI offer benefits with PSMA radiotracers, and PSMA PET findings frequently lead to changes in management. It is imperative that subsequent treatment changes be evaluated to show improved outcomes. PSMA PET also has potential applications, including patient selection for PSMA-based radioligand therapy and evaluation of treatment response.
本文旨在描述大量正在评估的用于前列腺特异性膜抗原(PSMA)PET 的放射性示踪剂,PSMA PET 已成为前列腺癌分期的重要工具。
与传统成像相比,PSMA PET 具有更高的检测率,因此是一种很有前途的前列腺癌分期方法。PSMA 放射性示踪剂的 PET/CT 和 PET/MRI 均具有优势,PSMA PET 的发现常常导致治疗方式的改变。必须评估后续的治疗改变,以显示出更好的结果。PSMA PET 还具有潜在的应用,包括基于 PSMA 的放射性配体治疗的患者选择和治疗反应的评估。
