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.
