Predicting Treatment Response in Primary Aldosteronism Using 11 C-Metomidate Positron Emission Tomography

Appropriate treatment of primary aldosteronism (PA) depends on accurate lateralization. 11 C-metomidate (MTO) is a tracer used in PET that provides functional information about the adrenal cortex. We aimed to perform MTO PET for patients with PA who are managed according to the guideline and to verify its correlation with other lateralization modalities and usefulness in outcome prediction.
