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.



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.


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.
