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.

Detailed description

Following the results of radiation dosimetry from this study then next steps will be taken for groups 2 & 3 using hormone manipulation.
