title: One-dimensional chemical shift imaging of fluorinated neuroleptics in rat brain in vivo by 19F NMR rotating frame zeugmatography.
abstract: One-dimensional chemical shift imaging reflecting local tissue contents of the fluorinated neuroleptics fluphenazine and trifluoperazine in rat brain was obtained noninvasively in vivo using one-dimensional 19-fluorine (19F) nuclear magnetic resonance (NMR) rotating frame zeugmatography. Activities of these fluorinated neuroleptics showed a differential distribution in the brain, maximal in the deep structures presumably within the basal ganglia. An additional resonance of an unidentified fluorinated metabolite was localized to the subcutaneous tissue. The present data indicate the feasibility of chemical shift imaging of fluorinated neuroleptics using a high field NMR system and the potential for future development of neurotransmitter imaging by NMR.
