18F-FLUC-CEST PET/MR in Patients With Brain Mets

Study Purpose

The goal of this clinical trial is to use new imaging methods to help in finding out whether the imaging shows that there is a tumor in people with a brain metastasis. The main question it aims to answer is whether positron emission tomography (PET) and magnetic resonance imaging (MRI) find cancerous tissue better than other types of imagining. Participants will undergo a single PET/MRI scan, followed by a separate MRI scan with a tracer. Study participation will last about 3 hours.

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 ClinicalTrials.gov, 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

The purpose of this research is to utilize new imaging methods to aid in assessing whether imaging shows presence of tumor. Developing imaging technologies is critical for more accurately identifying location and amount of tumor, which will then lead to improvements in future cancer therapy. This study aims to evaluate imaging methods known as PET and MRI to improve detection of cancerous tissue better than the types of imaging that are currently available. These methods are conducted on the same machine as conventional MRI that uses a powerful magnet, radio waves, and a computer to create detailed images. Both the PET and MRI methods look at the number of proteins a tumor has. The more proteins, the more likely there is tumor relative to normal brain tissue.
