Automatic segmentation of multiple sclerosis (MS) lesions in brain MRI has been widely investigated in recent years with the goal of helping MS diagnosis and patient follow-up. In this study we applied gaussian mixture model (GMM) to segment MS lesions in MR images. Usually, GMM is optimized...
Based on the generative adversarial network (GAN), we propose a semantic segmentation framework MS-GAN to localize MS lesions in multimodal brain magnetic resonance imaging (MRI), which consists of one multimodal encoder-decoder generator G and multiple discriminators D corresponding to the multiple ...
Tests are often used, along with a medical history and neurological exam, to diagnose MS and rule out other causes of symptoms. More than 90% of people with MS have scar tissue that shows up on anMRI scan. A spinal tap can check for abnormalities in the fluid that bathes the brain and...

Lesions to the brain's signal-carrying white matter are the most readily detectable manifestation of MS on MRI. The lesions, linked to the loss of the protective coating around white matter fibers called myelin, represent only macroscopic tissue damage. A means to find changes in the brain a...
In the case ofmultiple sclerosis (MS), MRI scans are done of the brain and sometimes spinal cord to spot damage to, or lesions on, portions of the myelin sheath, a fatty coating that protects nerve cell fibers, or axons. “MRI is critical in thediagnosis of MS,” saysRobert Zivadinov...
