Scatter Correction for Heart SPECT images Using TEW method
Radionuclide imaging has the potential to be used in quantitative analysis of the regional function of organs. However, quantification of SPECT images is degraded by many factors such as Compton photon scattering. This could have a destructive effect on clinical reports so it is important to do scatter correction to get better quality SPECT images. We intended to determine how scatter correctio...
متن کاملSPECT/CT using 67Ga and 111In-labeled leukocyte scintigraphy for diagnosis of infection.
UNLABELLED The present study evaluated the role of SPECT/CT as an adjunct to (67)Ga (GS) or (111)In-labeled white blood cell (WBC) scintigraphy for diagnosis or localization of infection. METHODS Eighty-two patients (56 male and 26 female; mean age, 62 y) assessed for known or suspected infectious processes underwent 88 SPECT/CT studies. Forty-seven patients underwent GS SPECT/CT (13 with fev...
متن کاملPreparation and Biodistribution of [67Ga]-labeled- oxytocin for SPECT purposes
Background: Oxytocin (OT) is a paracrine hormone with various biological activities and many sex organs in both sexes, as well as many tumor cells have shown to have related receptors. In this study the development of a receptor imaging tracer for possible tumor imaging has been described. Materials and Methods: OT was successively labeled with [67Ga]-gallium chloride after conjugation with fre...
متن کاملBiodistribution and kinetics of 67Ga- β-neurotoxin using SPECT molecular imaging
At least venomous snake bites 2000 persons each year in US. The severity of envenomation depends of the snake specie, its size, location of the bite and quantity of venom injected; but also depends of the health of the victim, age, size, and the time it takes to receive medical care. The envenomation is a medical emergency that requires fast attention to avoiding fatalities; in this sense, know...
متن کاملEfforts to Improve the Images from 67Ga Whole-Body Scintigraphy
The acquisition method for planar 67Ga imaging has hardly changed for 30 years. In this study, in order to improve image quality and diagnostic accuracy, we take steps to optimize the acquisition method, and to choose a scatter correction. First, we acquired individual images from the 93 keV, 185 keV, and 300 keV photopeak; then the images were added together and compared to the individual imag...
