Testing a new brain imaging tracer in healthy adults and people with multiple sclerosis

Researchers are testing a new radioactive tracer called [18F]-FZTA that can help detect inflammation in the brain using a special imaging scan called a PET scan. This study will first check that the tracer is safe in healthy adults, and then use it to image the brains of both healthy people and people with multiple sclerosis to see how well it works.

Multiple sclerosis involves inflammation in the brain that can be hard to see with standard imaging. This new tracer may help doctors better detect and understand this inflammation, which could lead to better ways to diagnose and monitor the disease.
