New MRI clue could slash MS misdiagnosis rates

NCT ID NCT04495556

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is testing whether a specific feature on brain MRI scans—called the central vein sign—can improve the accuracy of multiple sclerosis (MS) diagnosis. Currently, up to 1 in 5 people diagnosed with MS are later found not to have the disease, leading to unnecessary and potentially harmful treatments. The study will enroll 420 participants with typical or atypical MS symptoms across North America and compare MRI findings at the start and after 24 months to see if the central vein sign helps confirm or rule out MS.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to

If successful, this could lead to a more accurate and faster way to diagnose multiple sclerosis, reducing misdiagnosis and unnecessary treatments.

What could go wrong

This is an observational study, not a treatment trial. The central vein sign may not prove reliable enough to replace current diagnostic methods, and results may not apply to all patient groups.
