Abstract

Dopamine transmission in the ventral striatum (VST), a structure which includes the nucleus accumbens, ventral caudate, and ventral putamen, plays a critical role in the pathophysiology of psychotic states and in the reinforcing effects of virtually all drugs of abuse. The aim of this study was to assess the accuracy and precision of measurements of D(2) receptor availability in the VST obtained with positron emission tomography on the high-resolution ECAT EXACT HR+ scanner (Siemens Medical Systems, Knoxville, TN, U.S.A.). A method was developed for identification of the boundaries of the VST on coregistered high-resolution magnetic resonance imaging scans. Specific-to-nonspecific partition coefficient (V(3)") and binding potential (BP) of [(11)C]raclopride were measured twice in 10 subjects, using the bolus plus constant infusion method. [(11)C]Raclopride V(3)" in the VST (1.86 +/- 0.29) was significantly lower than in the dorsal caudate (DCA, 2.33 +/- 0.28) and dorsal putamen (DPU, 2.99 +/- 0.26), an observation consistent with postmortem studies. The reproducibility of V(3)" and BP were appropriate and similar in VST (V(3)" test-retest variability of 8.2% +/- 6.2%, intraclass correlation coefficient = 0.83), DCA (7.7% +/- 5.1%, 0.77), DPU (6.0% +/- 4.1%, 0.71), and striatum as a whole (6.3% +/- 4.1%, 0.78). Partial volume effects analysis revealed that activities in the VST were significantly contaminated by counts spilling over from the adjacent DCA and DPU: 70% +/- 5% of the specific binding measured in the VST originated from D(2) receptors located in the VST, whereas 12% +/- 3% and 18% +/- 3% were contributed by D(2) receptors in the DCA and DPU, respectively. Thus, accuracy of D(2) receptor measurement is improved by correction for partial voluming effects. The demonstration of an appropriate accuracy and precision of D(2) receptor measurement with [(11)C]raclopride in the VST is the first critical step toward the use of this ligand in the study of synaptic dopamine transmission at D(2) receptors in the VST using endogenous competition techniques.

  • The peak of the interaction effect was located in the caudate head, as part of the ventral striatum, but not in the nucleus accumbens proper.

    “Note, though, that the peak of this interaction effect was located in the caudate head, as part of the ventral striatum (Mawlawi et al., 2001), but not in the nucleus accumbens proper (see Fig. 2).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
