For most brain tumors, radiation treatment is guided by a Magnetic Resonance Imaging (MRI) scan. In this study, information from a special scan, called a Positron Emission Tomography/ Computed Tomography (PET/CT) scan using an amino acid called Fluorine-18-L-dihydroxyphenylalanine (18F-DOPA) will also be used. This type of scan has shown promise in being able to better distinguish tumor from normal brain tissue and may help to more accurately plan radiation treatment. This type of scan can also assist the radiation oncologist in identifying the most aggressive regions of the tumor. The goal of this study is to compare the 18F-DOPA PET/CT scan with the MRI scan for identifying where the disease is that needs to be treated with radiation.

Drug Fluorine-18-L-dihydroxyphenylalanine

5 millicuries ± 10%; Intravenous injection; 1 time

  • Other names: 18F-DOPA, FDOPA

Fluorine-18-L-dihydroxyphenylalanine None

18F-DOPA PET imaging will be used to guide radiotherapy treatment volumes and patients will be followed post-treatment to analyze response and patterns of failure
