Abstract
There is disclosed a radioligand labeled with a positron emitting radionuclide suitable for dynamic study in living humans with positron emission transaxial tomography. [.sup.18 F]-N-methylspiroperidol, exhibiting extremely high affinity for the dopamine receptors, provides enhanced uptake and retention in the brain concomitant with reduced radiation burden. These characteristics all combine to provide [.sup.18 F]-N-methylspiroperidol as a radioligand superior to known radioligands for mapping dopamine receptors in normal and disease states in the living brain. Additionally, a new synthetic procedure for this material is disclosed.
