The clear diagnosis of primary aldosteronism；
Combined with autonomous cortisol secretion, cortisol after 1mg dexamethasone suppression test (DST) ≥50 nmol/l；
Patients who are willing to undergo surgery；
PA patients who meet the by-passing AVS criteria [i.e., younger than 35 years old, spontaneous hypokalemia, adrenal CT indicated unilateral low-density adenoma (≥1cm), plasma aldosterone >300pg/ml]；
Suspicion of familial hyperaldosteronism or Liddle syndrome. [i.e., age <20 years, hypertension and hypokalemia, or with family history]；
Suspicion of pheochromocytoma or adrenal carcinoma；
Patients with actively malignant tumor；

Cohort
Prospective
68Ga-Pentixafor PET/CT
Diagnostic testThe patients had a normal diet with no special preparation before 68Ga-Pentixafor PET/CT imaging. The dosage of intravenously injected 68Ga-Pentixafor was calculated based on the patient\'s weight (1.85 MBq \[0.05mCi\]/kg). Local PET/CT scanning of the upper abdomen was performed on a hybrid PET/CT scanner at 10 minutes after the injection of the intravenous tracer, respectively.
