Differentiation between posttherapy radiation necrosis and recurrent tumor in humans with
brain tumor is still a difficult diagnostic task. The new PET tracers 18F-fluoro-ethyl-l-tyrosine …

The aim of this study was to investigate the potential of O-(2-18F-fluoroethyl)-l-tyrosine (18F-
FET) PET for differentiating local recurrent brain metastasis from radiation necrosis after …

Imaging of the glial activation that occurs in response to central nervous system trauma and
inflammation could become a powerful technique for the assessment of several …

Objective: To compare potentials of magnetic resonance imaging (MRI), F-18 FDG, and 11C-
Choline PET/CT in differentiating brain tumor recurrence from necrosis after radiotherapy …

Introduction Discrimination between (high-grade) brain tumor recurrence and radiation
necrosis (RN) remains a diagnostic challenge because both entities have similar imaging …

Introduction The positron emission tomography (PET) tracers 18 F-fluoro-ethyl-L-tyrosine
(FET), 18 F-fluorocholine (N, N-dimethyl-N-[18 F] fluoromethyl-2-hydroxyethylammonium …

Nine radiation-treated brain tumor patients were studied by positron emission tomography
(PET) in an attempt to differentiate tumor recurrence from radiation necrosis. Rubidium-82 …

Background The aim of this study was to investigate the potential of dynamic O-(2-[18F]
fluoroethyl)-L-tyrosine (18F-FET) PET for differentiating local recurrent brain metastasis from …

We evaluated the diagnostic accuracy of PET with l-methyl-11C-methionine (11C-MET) for
the differentiation of recurrent brain tumors from radiation necrosis. Methods: Seventy-seven …

18F-Fluorocholine (fluoromethyl-dimethyl-2-hydroxyethylammonium [FCH]) has been
developed as an oncologic probe for PET. This study evaluates the kinetics and radiation …
