Reliability and precision of pseudo‐continuous arterial spin labeling perfusion MRI on 3.0 T and comparison with 15O‐water PET in elderly subjects at risk for Alzheimer's disease
Arterial spin labeling (ASL) offers MRI measurement of cerebral blood flow (CBF) in vivo, and may offer clinical diagnostic utility in populations such as those with early Alzheimer's disease (AD).… Expand
Brain imaging of 18F‐fallypride in normal volunteers: Blood analysis, distribution, test‐retest studies, and preliminary assessment of sensitivity to aging effects on dopamine D‐2/D‐3 receptors
Human studies of dopamine D2/D3 receptors using 18F‐fallypride‐PET in normal volunteers were performed to evaluate brain distribution in striatal and extrastriatal regions, evaluate metabolites in… Expand
Digital tomosynthesis in breast imaging.
PURPOSE To describe and evaluate a method of tomosynthesis breast imaging with a full-field digital mammographic system. MATERIALS AND METHODS In this tomosynthesis method, low-radiation-dose… Expand
Evaluation of Dopamine D-2 Receptor Occupancy by Clozapine, Risperidone, and Haloperidol In Vivo in the Rodent and Nonhuman Primate Brain Using 18F-Fallypride
- J. Mukherjee, B. Christian, T. Narayanan, B. Shi, J. Mantil
- 1 October 2001
We have used the high-affinity dopamine D-2 receptor radioligand, 18F-fallypride for evaluating receptor occupancy by the antipsychotic drugs, clozapine, risperidone, and haloperidol in rodents and… Expand
Prediction of Pathology and Survival by FDG PET in Gliomas
AbstractObjectives: Despite being in use for nearly two decades, the utility of [18F]2-fluoro-2deoxy-d-glucose positron emission tomography (FDG PET) in the evaluation and treatment of brain tumors… Expand
Love to Win or Hate to Lose? Asymmetry of Dopamine D2 Receptor Binding Predicts Sensitivity to Reward versus Punishment

- 1 May 2014
We examined the hypothesis that in healthy participants this motivational bias (assessed by self-report and by a probabilistic learning task that allows direct comparison of the relative sensitivity to reward and punishment) reflects lateralization of dopamine signaling. Expand
Association of Insulin Resistance With Cerebral Glucose Uptake in Late Middle-Aged Adults at Risk for Alzheimer Disease.
IMPORTANCE Converging evidence suggests that Alzheimer disease (AD) involves insulin signaling impairment. Patients with AD and individuals at risk for AD show reduced glucose metabolism, as indexed… Expand
Quantitation of striatal and extrastriatal D‐2 dopamine receptors using PET imaging of [18F]fallypride in nonhuman primates
[18F]Fallypride is a highly selective, high‐affinity dopamine D‐2 receptor ligand. The high affinity, KD = 30 pM, makes it a suitable candidate for visualizing both striatal and extrastriatal binding… Expand
Dynamic PET Denoising with HYPR Processing

- 1 July 2010
We introduced the modified HYPR algorithm (the HYPR method constraining the backprojections to local regions of interest [HYPR-LR]) for the processing of dynamic PET studies. Expand
Longitudinal changes in amyloid positron emission tomography and volumetric magnetic resonance imaging in the nondemented Down syndrome population
Down syndrome (DS) arises from a triplication of chromosome 21, causing overproduction of the amyloid precursor protein and predisposes individuals to early Alzheimer's disease (AD).
