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 ...

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.

Positron Emission Tomography

2016
Positron emission tomography (PET) is a minimally invasive imaging procedure with a wide range of clinical and research applications. PET allows for the three-dimensional mapping of administered positron-emitting radiopharmaceuticals such as (18)F-fluorodeoxyglucose (for imaging glucose metabolism).

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 and Epilepsy

Molecular Imaging & Biology, 2002
This review examines the current role of positron emission tomography (PET) in the investigation and management of patients with epilepsy.A literature review utilizing MEDLINE(R) and other sources was undertaken. For the comparison of the accuracy of PET with magnetic resonance imaging (MRI) for seizure focus localization, only publications since 1994 ...

Positron Emission Tomography of the Brain

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 (PET)

Journal of Medical Systems, 1982
Among 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 ...

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 ...
