Is this trial a fit for you?

Likely a good fit

Ideal candidates include healthy individuals without known adrenal pathology and those with abnormal adrenal cortical hormone secretion.

Probably not a fit

Patients with known adrenal pathology who are not part of the study group may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the use of a fluorine-18 analogue of NP-59 ([18F]FNP-59) to improve PET imaging of the adrenal gland. Participants include healthy individuals undergoing hormone manipulation and those with known adrenal pathology. The study aims to assess the feasibility and effectiveness of this radiotracer in providing better imaging characteristics, including improved localization and sensitivity. All participants will undergo PET/CT scans after receiving the radiotracer.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of adrenal gland imaging, leading to better diagnosis and management of adrenal disorders.

How similar studies have gone: Other studies using similar imaging techniques have shown promise, but this specific approach with [18F]FNP-59 is novel.
