Objective: Reconstruction parameters must be optimized to approach the improved spatial resolution that is theoretically possible from modern SPECT imaging devices. One important reconstruction consideration is proper selection of the back-projection filter parameters. The aim of this study was to determine which Butterworth filter optimized image resolution for brain SPECT scans. Methods: Ten ...
Chemical reactions between oil-sands and injected steam or condensate during cyclic stimulation (CSS), commonly used to mobilize heavy oil bitumen, result in decomposition of pre-existing minerals formation new phases including clay minerals. These changes can reduce reservoir permeability limit hydrocarbon recovery. In this study, the chemical stable isotope compositions berthierine smectitic ...
BACKGROUND The melanin-concentrating hormone receptor 1 (MCHR1), which is highly expressed in the lateral hypothalamus, plays a key role in energy homeostasis, obesity and other endocrine diseases. Hence, there is a major interest in in vivo imaging of this receptor. A PET tracer would allow non-invasive in vivo visualization and quantification of the MCHR1. The aim of the study was the ex vivo...
PURPOSE This research was conducted to assess the biocompatibility of the core-shell Fe(3)O(4)@ Au composite magnetic nanoparticles (MNPs), which have potential application in tumor hyperthermia. METHODS Fe(3)O(4)@Au composite MNPs with core-shell structure were synthesized by reduction of Au(3+) in the presence of Fe(3)O(4)-MNPs prepared by improved co-precipitation. Cytotoxicity assay, hemo...
Microstructures and Mechanical Properties of Sintered Ti-4% Fe Alloy Compacts by Injection Moldings.
Our objective was to study 2 radioligands for visualization of -receptors with PET. Methods: Two radioligands— 1-selective 11C-1-(3,4-dimethoxyphenethyl)-4-(3-phenylpropyl)piperazine (11C-SA4503) and nonsubtype-selective 1-(4–2 -18F-fluoroethoxy-3-methoxyphenethyl)-4-(3-(4-fluorophenyl)propyl)piperazine (18F-FE-SA5845)—were evaluated for tumor imaging. Results: Binding studies to rat glioma cel...
