Positron Emission Tomography

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 ...

Diagnostic Accuracy of Positron Emission Tomography/Computed Tomography of the Head, Neck, and Chest for Giant Cell Arteritis: A Prospective, Double‐Blind, Cross‐Sectional Study

Arthritis & Rheumatology, 2019
Positron emission tomography/computed tomography (PET/CT) has not been well studied as a first‐line test for giant cell arteritis (GCA), due, in part, to historical limitations in visualizing the cranial arteries.

Overview of Positron Emission Tomography, Hybrid Positron Emission Tomography Instrumentation, and Positron Emission Tomography Quantification

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.

Outcomes of Primary Lymph Node Staging of Intermediate and High Risk Prostate Cancer with 68Ga-PSMA Positron Emission Tomography/Computerized Tomography Compared to Histological Correlation of Pelvic Lymph Node Pathology

Journal of Urology, 2019
Purpose: The majority of men who undergo pelvic lymph node dissection at radical prostatectomy have benign lymph node histology. The aim of this study was to assess the predictive value of preoperative 68Ga-PSMA (prostate specific membrane antigen ...

Positron Emission Tomography

1994
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]

open access: possiblePET 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.

(18)F-Labeling of Arenes and Heteroarenes for Applications in Positron Emission Tomography.

Chemical Reviews, 2016
Diverse radiochemistry is an essential component of nuclear medicine; this includes imaging techniques such as positron emission tomography (PET). As such, PET can track diseases at an early stage of development, help patient care planning through ...

Positron emission tomography in neuropsychology

Neuropsychologia, 1986
By 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.
