Purpose The vesicular acetylcholine transporter (VAChT) is a specific biomarker for imaging presynaptic cholinergic neurons. each tracer was completed in 55-60 min. Conclusions Two potent enantiopure VAChT ligands were synthesized and 11C-labeled with good radiochemical yield and specific activity. and study changes in MDL 28170 cholinergic function in response to therapy. Until recently only one… Continue reading Purpose The vesicular acetylcholine transporter (VAChT) is a specific biomarker for
