摘要

Currently available positron-emitting radiotracers for imaging of the alpha 4 beta 2 subtype of nicotinic acetylcholine receptors (nAChRs) exhibit high and moderate specific binding in the thalamus and extra-thalamic brain regions, respectively. In many neuropsychiatric disorders, alpha 4 beta 2-nAChRs are altered in the extra-thalamic brain regions, but not necessarily in the thalamus. The purpose of this study was to evaluate [F-18]XTRA, a new alpha 4 beta 2-nAChR positron emission tomography (PET) radioligand with improved specific binding in extra-thalamic brain regions, in non-human primates.
