Nuclear Imaging for Subtype Diagnosis of Primary Aldosteronism

Primary Aldosteronism

This study is to evaluate the accuracy of a novel radiopharmaceutical tracer, para-chloro-2-\[18F\]fluoroethyl etomidate (CETO), used with positron emission tomography (PET) and computed tomography (CT), as a way to subtype unilateral vs. bilateral forms of Primary Aldosteronism, compared to AVS as a reference gold standard.
