Uptake of 18F-fluorocholine, 18F-fluoro-ethyl-L-tyrosine and 18F-fluoro-2-deoxyglucose in F98 gliomas in the rat
2006
Introduction
The positron emission tomography (PET) tracers 18F-fluoro-ethyl-L-tyrosine (FET), 18F-fluorocholine (N,N-dimethyl-N-[18F]fluoromethyl-2-hydroxyethylammonium (FCH]) and 18F-fluoro-2-deoxyglucose (FDG) are used in the diagnosis of brain tumours. The aim of this study was threefold: (a) to assess the uptake of the different tracers in the F98 rat glioma, (b) to evaluate the impact of blood-brain barrier (BBB) disruption and microvessel density (MVD) on tracer uptake and (c) to compare the uptake in the tumours to that in the radiation injuries (induced by proton irradiation of healthy rats) of our previous study.
