To study opiate receptors noninvasively in vivo using positron emission tomography, techniques for preferentially labeling opiate receptors in vivo can be used. The rate at which receptor-bound ligand clears from the brain in vivo can be predicted by measuring the equilibrium dissociation constant (KD) at 37 degrees C in the presence of 100 mM sodium(More)
We describe the use of carbon-11-labeled 3-N-methylspiperone, a ligand that preferentially binds to dopamine receptors in vivo, to image the receptors by positron emission tomography scanning in baboons and, for the first time, in a human. The method has now been used in 58 humans for noninvasive assessment of the state of brain dopamine receptors under(More)
