MRI scans play a key role in diagnosing MS, monitoring disease activity, and guiding treatment decisions by showing lesions and signs of inflammation in the brain and spinal cord. The scan itself is noninvasive and typically lasts 15 minutes to an hour, sometimes using a contrast dye to highlight active lesions. While the process can feel intimidating due to the enclosed space and noise, preparation and relaxation strategies can help reduce anxiety. MRI results help doctors determine whether MS is stable or changing and whether treatment adjustments may be needed, making regular scans an important part of ongoing MS care.
