18F-FMAU PET/CT and MRI for the Detection of Brain Tumors in Patients With Brain Cancer or Brain Metastases

Brief Summary

This early phase I trial tests the use of a radioactive tracer (a drug that is visible during an imaging test) known as 18F-FMAU, for imaging with positron emission tomography/computed tomography (PET/CT) in patients with brain cancer or cancer that has spread to the brain (brain metastases). A PET/CT scan is an imaging test that uses a small amount of radioactive tracer (given through the vein) to take detailed pictures of areas inside the body where the tracer is taken up. 18F-FMAU may also help find the cancer and how far the disease has spread. Magnetic resonance imaging (MRI) is a type of imaging test used to diagnose brain tumors. 18F-FMAU PET/CT in addition to MRI may make the finding and diagnosing of brain tumor easier.

Beschreibung

PRIMARY OBJECTIVES: I. Assess the correlation between multiparametric magnetic resonance imaging (mpMRI) radiomics and dynamic 2'-fluoro-5-methyl-1-beta-D-arabinofuranosyluracil (FMAU) PET kinetic analysis parameters. II. Explore the different pattern in radiomics mpMRI and FMAU PET kinetic analysis parameters between patients with presence or absence of recurrent tumor. OUTLINE: Patients receive 18F-FMAU intravenously (IV) and undergo a PET/CT scan over 60 minutes. Patients then undergo standard of care mpMRI over approximately 45 minutes. After completion of study intervention, patients are followed up at 24-96 hours after their 18F-FMAU PET/CT scan.
