Uptake of 18F-Fluorocholine, 18F-FET, and 18F-FDG in C6 Gliomas and Correlation with 131I-SIP(L19), a Marker of Angiogenesis

18F-AFETP, 18F-FET, and 18F-FDG imaging of mouse DBT gliomas.

UNLABELLED The goal of this study was to evaluate the (18)F-labeled nonnatural amino acid (S)-2-amino-3-[1-(2-(18)F-fluoroethyl)-1H-[1,2,3]triazol-4-yl]propanoic acid ((18)F-AFETP) as a PET imaging agent for brain tumors and to compare its effectiveness with the more-established tracers O-(2-(18)F-fluoroethyl)-l-tyrosine ((18)F-FET) and (18)F-FDG in a murine model of glioblastoma. The tracer (1...

Production and quality control of [18F]-FDG in Iran [Persian]

The use of [18F]-2-FDG has been increasing in recent years. This agent was originally used for evaluation of CNS glucose uptake and pathologic conditions by positron emission tomography (PET). In view of increasing demand for this agent, its production has been started at cyclotron dept., Nuclear research center for agriculture & Medicine-Karaj Iran (NRCAM). In this paper, [18F]-FDG synth...

18F-FDG uptake as a surrogate marker for antecedent ischemia.

Factors influencing the pattern and intensity of myocardial 18F-FDG uptake in oncologic PET-CT imaging

Introduction:Myocardial 18F-FDG uptake is highly variable in oncologic whole body 18F-FDG PET/CT studies, ranging from quite intense to minimal distribution. Intense or heterogeneous myocardial 18F-FDG uptake is undesirable as it may interfere with the visual or quantitative evaluation of tumoral invasion and metastases in pericardium, myocardiu...

Correlation of hypoxic cell fraction and angiogenesis with glucose metabolic rate in gliomas using 18F-fluoromisonidazole, 18F-FDG PET, and immunohistochemical studies.

UNLABELLED PET offers a noninvasive means to assess neoplasms, in view of its sensitivity and accuracy in staging tumors and potentially in monitoring treatment response. The aim of this study was to evaluate newly diagnosed primary brain tumors for the presence of hypoxia, as indicated by the uptake of 18F-fluoromisonidazole (18F-FMISO) and to examine the relationship of hypoxia to the uptake ...
