How MRIs Differ in Kids With MOGAD vs MS

Key Takeaway

Children with MOGAD often do not show the MS-type rim lesions, and a blood-vessel sign (central vein sign) appears in some lasting lesions but not in those that go away quickly.

What They Found

Researchers looked at brain scans from 65 children with MOG antibody disease (MOGAD) and checked 520 spots of damage (lesions). They found the central vein sign (CVS) — a thin line showing a small vein through a lesion — in about 30% of lesions and in about half of the children, but many lesions were too large or too small to test. Lesions with the CVS were more likely to stick around over time, while lesions without the CVS were more likely to disappear. The CVS was seen more often when scans were done after the child was past an acute attack, suggesting timing matters — it's like checking a bruise days later versus right after it happened. They did not find any paramagnetic rim lesions (PRLs) — a different MRI feature seen in MS — suggesting PRLs might help tell MOGAD apart from MS.

Who Should Care and Why

MS patients and caregivers should care because the study helps doctors tell some MRI differences between MOGAD and MS, which can affect treatment choices; think of it like distinguishing two similar-looking rashes that need different creams. Families of children with MOGAD can use this to understand why repeat scans and scan timing matter — a lesion might look different during an attack versus weeks later. Doctors and radiologists may use the presence or absence of CVS and PRLs as clues when deciding whether a child has MOGAD or MS, which affects long-term care plans. Caregivers should know that not finding a CVS or finding lesions that clear up is common and can be reassuring because many lesions in MOGAD disappear. Patients who have many lesions or persistent lesions might get closer follow-up, since the CVS was more common in lasting lesions.

Important Considerations

This study looked only at children with MOGAD and used clinical MRIs from different centers, so results may not apply exactly the same way to adults or to scans done with different machines. Many lesions could not be measured for CVS because they were too small or too blended together; this limits how sure we can be about the exact percentages. The study was retrospective (looking back at past scans) rather than a planned experiment, so timing and scan quality varied and could affect the findings.

MS Diagnostics Early Research Specific Symptoms

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 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.
