Brief Summary
Validation of \[18F\]-FES for imaging of estrogen receptors in the brain The primary objective of the study is to determine if \[18F\]-FES Positron Emission Tomography (PET) can be used to quantify the estrogen receptor expression in the human brain.

Outcome Measures
Primary Outcomes (1)
Quantification of estrogen receptors in the human brain
The primary objective of the study is to validate the use of a reference tissue model and an image derived input function for the quantification of ERs in the human brain, by \[18F\]FES PET, using pharmacokinetic modelling with arterial sampling as golden standard
1 year
Secondary Outcomes (1)
Evalution of the levels of circulating estradiol in two patient cohorts and to evaluate the imaging technique
1 year
