Positron Emission Tomography (PET) Imaging of Cholesterol Trafficking: Clinical Evaluation of [18F]FNP-59 in Normal Human Subjects (Groups 2, 3 & 4)

Description

Groups 2 & 3 used hormone manipulation using information gathered from Group 1 which identified radiation dosimetry and optimal uptake time.

Group 4 (added to the study later) includes participants with known adrenal pathology. They will not have study associated hormone manipulation.

All groups will be given a radio-tracer and PET/CT scans.

The researchers believe that a fluorine-18 analogue of NP-59, [18F]FNP-59, would greatly improve the imaging characteristics, by providing a PET imaging cholesterol analogue with significantly improved radiation dosimetry, and improved localization / sensitivity / specificity without concern of thyroid exposure.
