PURPOSE: The aim of this study was to validate a gradient-based segmentation method for GTV delineation on FDG-PET in NSCLC through surgical specimen, in comparison with threshold-based approaches and CT. MATERIALS AND METHODS: Ten patients with stag

BACKGROUND AND PURPOSE: [(18)F]-EF3 allows non-invasive detection of hypoxia. In the framework of its validation, we aimed at comparing its pharmacokinetics, biodistribution, metabolism and specificity for hypoxia with the hypoxia tracer [(18)F]-FMIS

PURPOSE: The 2-(2-nitroimidazol-1-yl)-N-(3,3,3-trifluoropropyl)acetamide (EF3) is a 2-nitroimidazole derivative which undergoes bioreductive activation under hypoxic conditions. Using the PET tracer [18F]EF3 in mice, tumour-to-muscle ratios ranging f

BACKGROUND AND PURPOSE: The primary objective of this study was to establish in vivo the relationship between 2-2-nitro-1H-imidazol-1yl-N-(2,2,3,3,3-pentafluoropropyl)-acetamide (EF5) adduct formation and intratumoral oxygen concentrations measured b

INTRODUCTION: Fluorodeoxyglucose (FDG) has been reported as a surrogate tracer to measure tumor hypoxia with positron emission tomography (PET). The hypothesis is that there is an increased uptake of FDG under hypoxic conditions secondary to enhanced

PURPOSE: Biological image-guided radiotherapy aims at specifically irradiating biologically relevant sub-volumes within the tumor, as determined for instance by PET imaging. This approach requires that PET imaging be sensitive and specific enough to

Biological image-guided radiotherapy requires that PET accurately identifies biologically relevant sub-volumes within a tumor. In this framework, an immobilization device was developed to study multi-imaging (CT, micro-MRI, micro-PET, and autoradiogr

BACKGROUND: Gemcitabine (dFdC, 2',2'-difluorodeoxycytidine) is a deoxycytidine nucleoside analog which has a marked effect on several enzymes involved in DNA synthesis and repair. Gemcitabine has been tested as a radiosensitizer in various biological
