Quantitative SPECT measures of dopamine D 2 like receptors with [ 123 I]epidepride is complicated by its high affinity and lipophilic metabolites. The purpose of this study was to use both parent (P) and lipophilic metabolites (M) as input functions in a kinetic paradigm and in comparison to the res
## Abstract We used the reversibly binding D2 dopamine receptor radioligand [^123^I]IBZM (iodobenzamide) to test whether the endogenous neurotransmitter dopamine competes in vivo for radiotracer binding measured with single photon emission computed tomography (SPECT). In a series of nonhuman primat
