Study Summary

This trial will use a PET scanner to test an improved method for differentiating tumor recurrence from radiation necrosis in glioblastoma patients. The new quantitative kinetic analytical methods using FDOPA in combination with FDG will provide crucial functional information to distinguish recurrent tumors from treatment-induced radiation changes in patients with treated brain neoplasms.

Who is the study for?
This trial is for adults over 18 with glioblastoma who've seen their cancer worsen on MRI after recent radiation and chemotherapy. They must be able to lie still for an hour, follow the study plan, and have a clinical need for PET-CT scans. Women must be postmenopausal or surgically sterile. Exclusions include pregnancy, potential childbearing without effective contraception, excessive weight, certain dietary habits before tests, high blood sugar levels, and inability to lie flat.Check my eligibility
What is being tested?
The trial is testing new ways to tell if brain tumors in glioblastoma patients are coming back or just changes from treatment using advanced PET and MRI scans with FDG (a glucose-based tracer) and FDOPA (an amino acid-based tracer). Researchers think these methods could help doctors better decide on treatments by providing more accurate information about the tumor's status.See study design
What are the potential side effects?
Potential side effects may include discomfort from lying still during scans and reactions to tracers like FDG or FDOPA such as allergic responses. The risks associated with standard PET-CTs and MRIs also apply here.

Experimental Treatment
Group I: DiagnosticExperimental Treatment5 Interventions
Study subjects will receive 18FDG via an IV before undergoing one PET/CT scan over 60 minutes. They will then receive an IV injection of Gadovist for contrast before undergoing a multiparametric MRI scan. Subjects will also receive (18)F-FDOPA via an IV before undergoing another PET/CT scan over 60 minutes.
