What the study is about

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.

Being studied: Dexamethasone (Group 2); Cosyntropin (Group 3); PET/CT Scan with FNP-59

Conditions: Radiotracer; Hypertension; Cholesterol
