Brief summary:
To evaluate 18F-FDOPA PET obtained from PET/CT or PET/MRI imaging in patients with newly diagnosed or recurrent gliomas.

Detailed description:
This clinical trial compares fluorine F-18 fluoro-dihydroxyphenylalanine (18F-fluorodopa or 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.

Arms:
arm 1: Patients receive 18F-fluoro-dihydroxyphenylalanine (18F-FDOPA) intravenously (IV) and then undergo positron emission tomography / computed tomography (PET/CT) or PET/magnetic resonance imaging (PET/MRI) scans 10 to 30 minutes later.

Interventions: intervention 1: 18F-fluoro-dihydroxyphenylalanine intervention 2: Positron emission tomography (PET) intervention 3: Computed tomography (CT) intervention 4: Magnetic resonance imaging
Intervention descriptions: intervention 1: Administered intravenously (IV) intervention 2: Component of an 18F-FDOPA PET/CT or PET/MRI scan intervention 3: Component of an 18F-FDOPA PET/CT intervention 4: Component of an 18F-FDOPA PET/MRI
