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

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details


  • 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.
