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 radiochemistry
Neuroimaging Clinics of North America, 2003Factors that place constraints on radio-chemists who are seeking to design and develop radiopharmaceuticals for PET imaging studies include the short half-lives of 11C and 18F, minimum radiochemical yield and specific activity requirements, and high radiation fields that are associated with multi-Curie quantities of PET radionuclides.

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 ...

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

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 (PET)
Journal of Medical Systems, 1982Among 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 ...

Cardiac positron emission tomography
Seminars in Nuclear Medicine, 1998Positron emission tomography (PET) is an intrinsically quantitative tool that provides a unique and unparalleled approach for clinicians and researchers to interrogate the heart noninvasively. The ability to label substances of physiological interest with positron-emitting radioisotopes has permitted insight into normal blood flow and metabolism and ...

Positron emission tomography (PET) transits from the research domain into mainstream clinical applications for oncology in unbelievable short period of time, during last few years. The emergency of PET as the functional imaging modality of choice for diagnostic purposes, therapy, and assessment of recurrence in cancer has led to an increasing demand ...

POSITRON EMISSION TOMOGRAPHY INSTRUMENTATION
Radiologic Clinics of North America, 2001Positron emission tomography scanning has evolved over the past 40 years from a tool used predominantly for research to a valued clinical imaging modality. Current PET scanners must perform high-quality whole-body PET and brain PET. There are several levels of PET devices from the dedicated, high-end scanners down to the hybrid PET-SPECT systems ...
