Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults diagnosed with primary aldosteronism and concurrent autonomous cortisol secretion who have adrenal nodules of 1 cm or larger.
✕Probably not a fit
Patients with conditions such as familial hyperaldosteronism, pheochromocytoma, or those who have had prior adrenal surgery may not benefit from this study.

What this trial studies
This observational study aims to assess the accuracy of 68Ga-Pentixafor PET/CT imaging in diagnosing primary aldosteronism concurrent with autonomous cortisol secretion in patients with adrenal nodules. It involves a multicenter, prospective design where 97 patients will undergo both adrenal venous sampling (AVS) and PET/CT scans. The results from these imaging techniques will be compared against AVS and postoperative remission to determine diagnostic accuracy. The study focuses on patients who are willing to undergo surgery and have specific hormonal profiles.
Why it matters
Potential benefit: If successful, this study could improve the diagnostic accuracy for patients with complex adrenal disorders, leading to better-targeted treatments.
How similar studies have gone: While the use of PET/CT in adrenal disorders is emerging, this specific application for concurrent primary aldosteronism and cortisol secretion is relatively novel and has not been extensively tested in prior studies.
