In vivo binding of the dopamine uptake inhibitor [18F]GBR 13119 in MPTP-treated C57BL/6 mice
(Elsevier, 1991)
The in vivo regional distribution of [18F]GBR 13119 (1-[(4-[18F]fluorophenyl(phenyl)methoxy)ethyl]-4-(3-phenylpropyl) piperazine), a specific dopamine reuptake inhibitor, was examined in brains of C57BL/6 mice after MPTP ...
Biodistribution, dosimetry, metabolism and monkey PET studies of [18F]GBR 13119. Imaging the dopamine uptake system in vivo
(Elsevier, 1989)
The in vivo charactersitics of a new radiotracer, [18F]GBR 13119, have been examined. Full body biodistribution in rats has been determined and the expected human dosimetry calculated. Pharmacological specificity of in ...
Effect of CT scanning parameters on volumetric measurements of pulmonary nodules by 3D active contour segmentation: a phantom study
(2008)
"The purpose of this study is to investigate the effects of CT scanning and reconstruction parameters on automated segmentation and volumetric measurements of nodules in CT images. Phantom nodules of known sizes were used ...
Improvement of integrated utrasonic transducer sensitivity
(Elsevier, 1989-06)
In this paper, we present a micromachined diaphragm structure for integrated ultrasound transducers. This structure greatly reduces the parasitic capacitance between the lower electrode and the conductive Si substrate in ...
Thiophenes as phenyl bio-isosteres: Application in radiopharmaceutical design--I. Dopamine uptake antagonists
(Elsevier, 1989)
Possible applications of thiophenes in radiopharmaceutical chemistry have been explored. Thiophene for benzene ring substitution was applied to the synthesis of thienyl-[18F]GBR 13119, an analog of the potent and selective ...
Quantitative characterization of hemodynamic properties and vasculature dysfunction of high-grade gliomas
(John Wiley & Sons, Ltd., 2007-10)
Aberrations in tumor and peritumoral vasculature may not be distinguishable by cerebral blood flow (CBF) or cerebral blood volume (CBV) alone. The relationships between CBF and CBV were examined to estimate vasculature-specific ...
Lower bounds on scintillation detector timing performance
(Elsevier, 1990-12-20)
Fundamental method-independent limits on the timing performance of scintillation detectors are useful for identifying regimes in which either present timing methods are nearly optimal or where a considerable performance ...
Direct simultaneous production of [15O]water and [13N]ammonia or [18F]fluoride ion by 26 MeV proton irradiation of a double chamber water target
(Elsevier, 1990)
A simple double liquid chamber target was developed to provide the option for simultaneous production of [15O]H2O and either 13N or 18F using a single proton beam. Irradiation of natural water in a thin aluminium front ...
Pituitary localization of 3H-spiroperidol by an Uptake/Storage Mechanism?
(Elsevier, 1986)
The lack of a pituitary imaging agent combined with the considerable clinical value for such an agent prompted an examination of 3H-spiroperidol (3HSp). Spiroperidol was selected for initial evaluation based on its high ...
