Healthy Controls Clinical Trial
Official title:
Positron Emission Tomography Study of alpha2-adrenergic Receptors With [11C]Yohimbine
The main purpose of this study is to model tissue specific kinetics of [11C]Yohimbine in healthy male participants by positron emission tomography (PET) and the appropriate arterial input function (part A) ; to determine the reproducibility of measures (classical test-retest study, part B1) and to measure the blocking of [11C]Yohimbine uptake in the brain following single oral dose administration of clonidine (part B2).
