PURPOSE This study was conducted to develop a new positron emission tomography (PET) method to visualize neurokinin-1 (NK(1)) receptor systems in the human brain in vivo in order to examine their neuroanatomical distribution and facilitate investigations of the role of substance P, NK(1) receptors, and NK(1) receptor antagonists in central nervous system(More)
PURPOSE The aim of the study was to compare (68)Ga-chloride with 2-[(18)F]fluoro-2-deoxy-D: -glucose (FDG) for the imaging of pancreatic xenografts. PROCEDURES Rats with subcutaneous human pancreatic adenocarcinoma xenografts were evaluated in vivo by dynamic positron emission tomography (PET) and ex vivo by measuring radioactivity of excised tissues and(More)
The [(18)F]fluoromethyl analog of (+)-McN5652 ([(18)F]FMe-McN) for imaging serotonin transporter (SERT) with positron emission tomography (PET) has recently been synthesized. We describe here the biological evaluation of [(18)F]FMe-McN in rats. Biodistribution studies of [(18)F]FMe-McN in rat brain ex vivo after an intravenous injection showed a high(More)
