Accuracy of 68Ga-Pentixafor PET/CT for Subtypting Diagnosis in Patients With Primary Aldosteronism Concurrent With Autonomous Cortisol Secretion

Обзор

To evaluate the accuracy of 68Ga-Pentixafor PET-CT in the classification diagnosis of primary aldosteronism concurrent with autonomous cortisol secretion patient, using AVS and/or postoperative remission as the reference standard for classification diagnosis.

Подробное описание

This study is a multicenter, prospective, diagnostic trial involving patients with primary aldosteronism (PA) concurrent with autonomous cortisol secretion (ACS) patients with adrenal nodule (≥1cm) who completed both AVS and 68Ga-Pentixafor PET/CT. We will enroll 97 PA concurrent with ACS patients with adrenal nodule (≥1cm) .The treatment plan was determined according to the AVS results. AVS and/or postoperative remission were used as the reference standard for classification diagnosis to evaluate the accuracy of 68Ga-Pentixafor PET-CT in the classification diagnosis of PA concurrent with ACS patients.

Вмешательства

• Диагностический тест 68Ga-Pentixafor PET/CT
  The 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.
