Molecular Imaging Versus Adrenal Vein Sampling for the Detection of Surgically Curable Primary Aldosteronism A Prospective Within-Patient Trial.

Background: Primary aldosteronism (PA) causes hypertension and is potentially surgically curable when it is caused by a unilateral aldosterone-producing adrenal adenoma (APA). Adrenal vein sampling (AVS) is required to guide surgery, but it is invasive, is technically difficult, and has limited availability.
