Overview
To compare the 68Ga-Pentixafor PET/CT and adrenal vein sampling on the long-term outcomes of primary aldosteronism (PA) patients with adrenal nodule (≥1cm)
Description
This is a randomized study involving patients with primary aldosteronism (PA) patients with adrenal nodule (≥1cm) who completed AVS or 68Ga-Pentixafor PET/CT.We will enroll 320 PA patients with adrenal nodule (≥1cm) .All paticipants will be randomized into 68Ga-Pentixafor PET/CT group(Intervention group) and AVS group(Control group) to compare the long-term outcomes of patients with PA.
