Tryptophan-kynurenine Pathway PET Imaging in Human Gliomas
Barbara Ann Karmanos Cancer Institute
Summary
The goal of this clinical trial is to evaluate Positron emission tomography/computed tomography (PET/CT) imaging with the radiotracer 1-(2-\[18F\]fluoroethyl)-l-tryptophan (\[18F\]FETrp) in patients diagnosed with a glioma. This study has 3 aims: * to assess if the \[18F\]FETrp PET/CT can outperform Magnetic Resonance Imaging (MRI) by providing a better treatment target volume in newly diagnosed Stage 4 glioma patients * better differentiate tumor progression from radiation induced MRI changes in post treatment stage 4 gliomas * by giving a drug that can inhibit a pathway to allow objective assessment of treatment effects in low grade gliomas
