New Brain Scans May Reveal Hidden Inflammation in MS
Key Takeaway
A review of 49 studies found that a special brain scan can detect signs of inflammation in MS, but differences in how scans are done limit its use in routine care.
What They Found
The researchers reviewed 49 studies of a PET scan, which uses a small amount of radioactive material to show activity inside the brain.On average, people with MS had stronger scan signals linked to inflammation than people without MS.People with progressive MS also had stronger signals than people with relapsing-remitting MS.Higher signals appeared in several brain areas, including tissue near MS lesions, which are areas of damage.Results varied greatly between studies, partly because researchers used different scanning materials, measurements, and brain areas.
Who Should Care and Why
People with MS and their caregivers may find this useful because inflammation can be hard to see or understand from symptoms alone.The scan may help researchers study what is happening in the brain, much like a heat map helps show where activity is strongest.It may be especially relevant to people with progressive MS, since the review found stronger signals in that group.For now, these findings do not mean you need to change your treatment or ask for this scan.If you have questions about changes in your symptoms or care, talk with your MS healthcare team about the tests and treatments available to you.
Important Considerations
Scan results differed greatly across studies, so a result from one scanning method may not mean the same thing as a result from another.The link between scan signals and disability was based on limited patient-level data, so it needs more study.Researchers need more consistent scan methods before doctors can reliably use this test to guide an individual person's MS care.

Whether you’ve recently been diagnosed with Multiple Sclerosis (MS) or are seeking to broaden your understanding of this complex, neurodegenerative disease, navigating the latest research can feel overwhelming. Studies published in respected medical journals like Neurology(R) neuroimmunology & neuroinflammation often range from early-stage, exploratory work to advanced clinical trials. These evidence-based findings help shape new disease-modifying therapies, guide symptom management techniques, and deepen our knowledge of MS progression.
However, not all research is created equal. Some clinical research studies may have smaller sample sizes, evolving methodologies, or limitations that warrant careful interpretation. For a more comprehensive, accurate understanding, we recommend reviewing the original source material—accessible via the More Details section above—and consulting with healthcare professionals who specialize in MS care.
By presenting a wide range of MS-focused studies—spanning cutting-edge treatments, emerging therapies, and established best practices—we aim to empower patients, caregivers, and clinicians to stay informed and make well-informed decisions when managing Multiple Sclerosis.
