Summary

This study looked at whether a special PET scan (18F-DOPA) can help doctors better see brain tumors when planning radiation therapy. 91 adults with newly diagnosed gliomas were enrolled. The goal was to see if this scan improves treatment planning and helps predict how well patients respond to therapy.
