Primary Outcome Measures
NameTimeMethod
Based on the PET data it follows the calculation of an activity quotient between tissue and plasma as a direct measure of the distribution volume of the radiotracer and therefore of the transporter availability in the separate individuals
Secondary Outcome Measures
NameTimeMethod
comparison of pulmonary SERT-availabilty between the individuals as well as subgroups
