Brief Summary

This study will evaluate the feasibility of using a sub-therapeutic dose of a fluorine-18 analogue of NP-59 (\[18F\]FNP-59) to image the adrenal gland. Some participants are healthy normal subjects but have undergone interventions to manipulate hormones while other participants have known adrenal pathology.

Eligibility Criteria

Inclusion Criteria (Groups 2 \& 3): * Participants without any known adrenal pathology as normal controls for undergoing endocrine manipulation Exclusion Criteria (Groups 2 \& 3): * Pregnancy * Unable to do imaging * Body weight greater than 400 lbs (181 Kg) * Prisoners are not eligible * Subjects unable to provide own consent are not eligible * Current use of steroids, Oral contraceptives (OCP), spironolactone, estrogen, androgen, progesterone, Angiotensin-converting enzyme (ACE inhibitors)/ Angiotensin II receptor blockers (ARBs), or supplements that are hormone analogues. * Known adrenal pathology Inclusion Criteria (Group 4): * Abnormal adrenal cortical hormone secretion Exclusion Criteria (Group 4): * Pregnant
