Positron emission tomography radiochemistry

Neuroimaging Clinics of North America, 2003
Factors 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.

Instrumentation in positron emission tomography

Neuroimaging Clinics of North America, 2003
The past 40 years have seen PET scanning evolve from a tool that was used predominantly for research to a valued clinical, imaging modality. Current PET scanners must perform high quality, whole-body, as well as brain, PET. There are several levels of PET devices that range from the dedicated, high-end scanners down to the hybrid PET-SPECT systems that

Positron emission tomography in oncology

Clinical Physiology, 1994
Summary. The particular advantages of positron emission tomography (PET) technique are that it has higher sensitivity, higher resolution, and a higher quality of image than that found in conventional nuclear medicine. The possibility of quantification and the wide range of useful tracers have raised expectations of this new method.

Positron emission tomography of the brain

Computerized Medical Imaging and Graphics, 1989
Positron emission tomography (PET) is a technique of transverse tomographic imaging in which detection of two photons emitted from the annihilation of a positron and an electron is used to reconstruct the distribution of a positron emitting isotope within an object.

Positron Emission Tomography for Neurologists

Neurologic Clinics, 2009
This short review focuses on practical, present day, clinical application of FDG PET, a technology available to practicing neurologists for managing their patients. Indications in the disease states of dementia, neuro-oncology, epilepsy, parkinsonism, and other less common settings are reviewed.

Positron Emission Tomography in Oncology

Clinical Journal of Oncology Nursing, 2003
Positron emission tomography (PET) scans use positrons, positively charged particles, to detect metabolic and chemical changes in the body. Although the clinical applications of this technology still are evolving, PET scans are being used to detect cancer and evaluate neurologic disorders, heart muscle function, and response to treatment.

The origins of positron emission tomography

Seminars in Nuclear Medicine, 1992
The development of positron emission tomography (PET) took place through the combination of the following recognitions: (1) a handful of short-lived, positron-emitting radionuclides, carbon-11, nitrogen-13, and oxygen-15, exhibit chemical properties that render them particularly suitable for the tracing of important physiological pathways, and (2) the ...

POSITRON EMISSION TOMOGRAPHY INSTRUMENTATION

Radiologic Clinics of North America, 2001
Positron 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 ...

Positron emission tomography: a review

1991
The origin of most medical problems is biochemical in nature. Positron emission tomography (PET) is a powerful tool to enlighten the underlying biochemical disorder in human disease. Therefore, the biochemical information obtained by PET allows an understanding of the fundamental nature of human disease and provides diagnosting examinations with a high
