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

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 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.
