Physics in Medicine and Biology, 1988
The developments in positron emission tomography (PET) are reviewed with an emphasis on instrumentation for clinical PET imaging. After a brief summary of positron imaging before the advent of computed tomography, various improvements are highlighted including the move from PET scanners with septa to fully 3D scanners, changes in the preferred ...

Annual Review of Neuroscience, 1980
An understanding of disease processes in the human brain must ultimately be based on a knowledge of the underlying regional hemodynamic, metabolic, and biochemical changes. Although some such information is currently available from various animal models, the conflicting nature of these data often leaves many important questions unanswered and ...

Psychiatric Clinics of North America, 1986
PET is a unique tool for the direct in vivo evaluation of physiologic processes within discrete areas of the brain. Thus far, its application to the study of schizophrenia has served to confirm the subtleties of this illness. However, PET does promise to increase our knowledge of the neurochemical anatomy of the normal and abnormal mind with respect to

Ophthalmology, 2012
We report the correlation of the neuro-ophthalmological findings with a 18 F-fluorodeoxyglucose positron emission tomography-computed tomography study ( 18 F-FDG-PET/ CT) in a pediatric patient affected by a pure right homon- ymous hemianopia manifested after minor head injury and no evidence of any lesions at other neuroimage studies, visual evoked ...

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.
