This pilot clinical trial studies gallium Ga 68-edotreotide (68Ga-DOTATOC) positron emission tomography (PET)/computed tomography (CT) in finding brain tumors in younger patients. Diagnostic procedures, such as gallium Ga 68-edotreotide PET/CT imaging, may help find and diagnose brain tumors.
This clinical trial compares fluorine F 18 fluorodopa (18F FDOPA) positron emission tomography (PET) with standard magnetic resonance imaging (MRI) in measuring tumors in patients with glioma that is newly diagnosed or recurrent (has returned). 18F FDOPA is a radioactive drug that binds to tumor cells and is captured in images by PET. Computed tomography (CT) and MRI are used with PET to describe information regarding the function, location, and size of the tumor. PET/CT or PET/MRI may be more accurate than standard MRI in helping doctors find and measure brain tumors.
