Summary
Brief summary (as posted)
This clinical trial studies how well delayed fludeoxyglucose F-18 (18F-FDG) positron emission tomography (PET)/computed tomography (CT) works in improving visualization of brain tumors in patients with glioblastoma. Radiotracers such as 18F-FDG are highly taken up by tumors in the brain and are visualized using PET/CT. Increasing the interval of time between 18F-FDG administration and PET/CT scan may improve the visualization of brain tumors in patients with glioblastoma.
