SLC6A2 and attention deficit-hyperactivity disorder: Aim: The norepinephrine transporter (NET) is a monoamine transporter, which has an important role in several neuropshyciatric disorders, such as ADHD and schizophrenia.1 Our aim is to develop a cassette-based synthesis for 18F-fluorination 3-[(6-[18F]fluoro-2-pyridyl)oxy]-8-azabicyclo[3.2.1]octane ([18F]NS12137) using the TRASIS AllInOne module.
