New MRI technique sharpens diagnosis of swollen optic nerve

This study looked at whether a new, high-resolution MRI can help doctors more accurately and confidently diagnose the cause of optic disc swelling (a sign of various eye or brain problems). Researchers used these detailed scans on 197 adults with optic disc swelling to see if the images improved diagnosis compared to standard methods. The goal was to make diagnosis faster and more reliable for conditions like inflammation, pressure in the brain, or blocked blood flow.
