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.
揭示了一种功能性PET成像方法,用于区分双侧增生和单侧腺瘤,包括(1)将与CYP11 B1(11β-羟化酶)相对选择性结合于CYP11 B2(
醛固酮合成酶)的放射性标记CYP11 B2(
醛固酮合成酶)
抑制剂引入具有肾上腺的哺乳动物中,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性PET图像。还揭示了适用于此方法的放射性示踪剂化合物,用于制备其前体的方法以及制备放射性示踪剂化合物的过程,可作为快速的一锅反应进行。
