Positron Emission Tomography

Archives of Internal Medicine, 1990
Positron emission tomography (PET) is an imaging technique that provides quantitative, regional measurements of biochemical and physiological processes in living human subjects. In this editorial, we review PET's capabilities; we distinguish between its established, apparent, and unestablished but potential value in science and medicine; and we ...

Overview of Positron Emission Tomography, Hybrid Positron Emission Tomography Instrumentation, and Positron Emission Tomography Quantification

Journal of Thoracic Imaging, 2013
Positron emission tomography (PET) is a powerful quantitative molecular imaging technique that is complementary to structural imaging techniques for purposes of disease detection and characterization. This review article provides a brief overview of PET, hybrid PET instrumentation, and PET quantification.

Positron Emission Tomography

1994
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]

open access: possiblePET 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, 1986
By 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 ...

Positron emission tomography

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, 1985
Positron 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 ...
