We compared the contributions of the labeled tracers 11 C-methionine (Met) and 18 F-FDG
for PET-guided stereotactic biopsy of brain gliomas. Methods: In 32 patients with glioma, …

OBJECTIVE Integrating positron emission tomographic (PET) images into the image-guided
resection of high-grade gliomas (HGG) has shown that metabolic information on tumor …

Object The aim of this study was to evaluate the integration of positron emission tomography
(PET) scanning data into the image-guided resection of brain tumors. Methods Positron …

Serotonergic mechanisms are involved in gender-related behaviors and psychiatric conditions
like aggression, eating disorders, depression, impulsivity or suicide. We studied gender …

BackgroundSerotonin receptors may play an important role in the pathophysiology of
affective disorders. We studied type-2 serotonin (5-HT2) receptors in the brain of patients with …

Object. Positron emission tomography with l -[methyl-11C]methionine (MET-PET) provides
information on the metabolism of gliomas. The aim of this study was to determine the …

Object The purpose of this study was to measure the dose of radiation delivered to the cochlea
during a Gamma knife surgery (GKS) procedure for treatment of patients with vestibular …

In the management of brainstem lesions, the place of stereotactic biopsy sampling remains
debatable. The authors compared the results of magnetic resonance (MR) imaging, positron …

RESULTS In the total set of 93 tumor samples, tumor-to-cortex ratios calculated on MET-PET
and FDG-PET were highly positively correlated (Fig. 1, Spearman rho= 0.77, p< 0.0001). …

OBJECTIVE: The natural history of the supratentorial low-grade glioma (LGG) of the adult is
variable, and its malignant transformation is hardly predictable. Because positron emission …
