Positron computed tomography allows for the in vivo measurement of the regional tissue concentration of positron-emitting radionuclides such as 15O, 11C, 13N, and 18F. By using different tracers, a variety of metabolic processes can be quantitated. These include blood flow, oxygen utilization, glucose utilization, amino acid transport, blood volume ...

Positron Emission Tomography of the Brain [PDF]
PET Clinics, 2006 Positron emission tomography (PTE) is a technique that allows imaging of the temporal and spatial distribution of positron-emitting radionuclides. The purpose of this article is to outline the current clinical use for PET imaging in the brain and other radiopharmaceutical used for assessing various physiologic parameters pertaining to tumor metabolism.

Positron emission tomography in neuropsychology
Neuropsychologia, 1986By positron emission tomography (PET) of 18F-2-fluoro-2-deoxy-D-glucose (FDG) local cerebral metabolic rate for glucose (LCMRGl) can be measured in man. Normal values in cerebral cortex and basal ganglia range from 35 to 50 mumol/100 g/min, the values in gray matter structures of the posterior fossa were 25-30 mumol/100 g/min, the lowest LCMRGl was ...

18F-Fluoride Positron Emission Tomography and Positron Emission Tomography/Computed Tomography
Seminars in Nuclear Medicine, 2007(18)F-Fluoride is a positron-emitting bone-seeking agent, the uptake of which reflects blood flow and remodeling of bone. Assessment of (18)F-fluoride kinetics using quantitative positron emission tomography (PET) methods allows the regional characterization of lesions of metabolic bone diseases and the monitoring of their response to therapy.

Brain Topography, 1992
Positron emission tomography (PET) allows for the absolute measurement of regional tissue physiological, biochemical and pharmacological processes. This ability is a consequence of the nature of positron emission and the type of tracers which can be labelled with positron emitting radionuclides. The spatial resolution of state of the art scanners is in

Positron emission tomography in the lung
Journal of Thoracic Imaging, 1985Positron emission tomography using the ECAT II scanner to image and measure regional lung function is outlined. The combined use of transmission and emission imaging provides quantitative information about regional lung structure (density, extravascular density, and vascular volume) and function (ventilation, perfusion, ventilation-perfusion ratios ...

Positron emission tomography (PET)
Journal of Medical Systems, 1982Among emerging medical diagnostic imaging modalities, positron emission tomography, often abbreviated to its acronym “PET”, belongs in the category of nuclear medicine. Indeed, the image forming variable in PET is the distribution in the structure under study of a radionuclide administered systemically in the form of a selected radiopharmaceutical ...
