Para-chloro-2-[18F]Fluoroethyl-etomidate ([18F]CETO) as a New PET-tracer for Subtyping in Patients With Primary Aldosteronism - a Pilot Study
The goal of this clinical trial is to investigate the uptake characteristics of \[18F\]CETO in adrenal tissue in patients with two different subtypes of primary aldosteronism. The main questions it aims to answer are: * What are the uptake characteristics of \[18F\]CETO in adrenal tissue in patients with primary aldosteronism? * What is the concordance between the adrenal vein sampling and the \[18F\]CETO PET/CT scan results? * What is the effect of adrenal perfusion on \[18F\]CETO uptake in the adrenal glands? Researchers will compare the results of the adrenal vein sampling to a \[18F\]CETO PET/CT scan to see if the PET/CT can accurately identify the subtypes of primary aldosteronism. Participants will: * Take dexamethasone three days prior to the scan * Undergo a \[18F\]CETO PET/CT * Report burden of pre-treatment and PET/CT scan
