Subtyping Primary Aldosteronism With Para-chloro-2-[18F]Fluoroethyl-etomidate

PET/CT with para-chloro-2-\[18F\]fluoroethyl-etomidate (\[18F\]CETO) has a high specificity for the steroidogenic enzymes CYP11B1 and CYP11B2, present in the adrenal cortex, and has more favourable tracer characteristics compared to \[11C\]metomidate. Results obtained with this novel tracer seem promising, but its potential value in the subtyping of PA needs to be further established.
