The management and prognosis of patients with glioma is highly dependent on the tumour grade according to the new 2016 classification of the World Health Organization (WHO), which incorporates molecular characteristics. Standard magnetic resonance imaging (MRI) enhanced by contrast is the basis of
Low-grade glioma is a malignant tumor of young adults (12.5% of gliomas, incidence of 0.99 / 100,000). Median survival, linked to anaplastic transformation is estimated between 7 and 10 years, with great individual variability in the rate of evolution. The morphological MRI, standard assessment tool
For glioblastoma (GBM) patients it has been proven that a [18F]FET-PET scan is very helpful especially in target volume definition and after the treatment, in turn, the combination of MRI and [18F]FET-PET is diagnostically most useful to distinguish between radiation necrosis and a real progressive
The higher sensitivity and specificity of amino-acids (L-[methyl-11C]-methionine, MET and O-(2-(1)-Fluoroethyl)-L-tyrosine, FET) positron emission tomography (AA-PET) in the diagnosis of gliomas in comparison to computed tomography (CT) and magnetic resonance imaging (MRI) was demonstrated in many
The objectives of the study are:
- To demonstrate if the multimodal approach, combining the morphological aspect of the MRI with the metabolic aspect of the tumor with magnetic resonance spectroscopy (MRS) and O-(2-[18F]-fluoroethyl)-L-tyrosine (FET) or 18F]-fluorocholine (FCH) PET/CTthe FCH allows
