Brief Summary

This exploratory, first-in-man, phase 0 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 in healthy normal subjects. The researchers believe that \[18F\]FNP-59 would greatly improve the imaging characteristics, by providing a PET imaging cholesterol analogue with significantly improved radiation dosimetry.

Eligibility Criteria

Inclusion Criteria: * Participants without any known adrenal pathology as normal controls for radiation dosimetry purposes Exclusion Criteria: * 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
