To evaluate the value of 68Ga-Pentixafor PET/CT in the diagnosis of primary aldosteronism subtype


This is a prospective study. We will enroll 100 patients with definite diagnosis of PA using adrenal venous sampling(AVS) as the gold standard for subtype to evaluate the value of 68Ga-pentixaforPET/CT in the diagnosis of PA.

Condition Primary Aldosteronism
Treatment Aldosterone/renin ratio(ARR) testing
