A functional PET imaging method is disclosed for differentiation between bilateral hyperplasia and unilateral adenoma comprising (1) introducing a radioactively labelled CYP11 B2 (aldosterone synthase) inhibitor which binds selectively to CYP11 B2 (aldosterone synthase) relative to CYP11 B1 (11β-hydroxylase) into a mammal with adrenal glands and (2) conducting positron emission tomography (PET) in the region of the adrenal glands to obtain a functional PET image of the adrenal glands. Also disclosed are radioactive tracer compounds suitable for use in this method, precursors for making the same, and a process for making the radioactive tracer compounds capable of being conducted as a rapid one-pot reaction.
揭示了一种用于区分双侧增生和单侧腺瘤的功能PET成像方法,包括(1)将一种放射性标记的CYP11 B2(醛固酮合成酶)抑制剂引入到具有肾上腺的哺乳动物中,该抑制剂相对于CYP11 B1(11β-羟化酶)选择性地结合到CYP11 B2(醛固酮合成酶),以及(2)在肾上腺区域进行正电子发射断层扫描(PET)以获得肾上腺的功能PET图像。还披露了适用于该方法的放射性示踪化合物、用于制备这些化合物的前体以及制备能够作为快速一锅反应进行的放射性示踪化合物的过程。
