Brief summary: This study validates dexamethasone-suppressed [11C]metomidate positron emission tomography computed tomography (MTO) scanning as a CYP11B2-selective investigation for lateralizing PA.Primary aldosteronism (PA) is the most common single cause of hypertension, accounting for 5–14% of all cases and 20–25% of treatment-resistant hypertension (1, 2). Traditionally, patients with PA are divided equally into ...
