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 ...

Clinical Physics and Physiological Measurement, 1988
While positron emission tomography (PET) represents the most advanced methodology using radiotracers, it is subject to two main constraints. The first is the physical accuracy with which the regional distribution, time course and concentration of the tracer can be determined. This is principally a function of the instrumentation.

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 ...

Radiation Physics and Chemistry (1977), 1984
One of the most exciting new techniques introduced in the last ten years is positron emission tomography (PET). PET provides quantitative, three-dimensional images for the study of specific biochemical and physiological processes in the human body.

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

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 ...

Positron emission tomography (PET) is based on the detection in coincidence of the two 511-keV annihilation radiations that originate from β + -emitting sources, such as the patient containing β + -emitting radioactivity. Positrons are annihilated in body tissue and produce two 511-keV annihilation photons that are emitted in opposite directions (180°).

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.
