*Premorbid intelligence was estimated by extrapolating IQ values from the Multiple-Choice Vocabulary Intelligence Test.
The specific tracer activity was M = 32.58 GBq/µmol, SD = 11.04. This value was an estimation based on standard values acquired for quality control. Within the setup, the specific activity was not measured directly.
