MS can take a toll on mental sharpness. Some people may find it takes longer to solve problems. Others may have mild memory loss or trouble concentrating. Most people with MS also experience some loss of bladder control, because signals between the brain and bladder are interrupted. Finally, ...
Multiple sclerosis is a disease that causes demyelination of the brain and spinal cord nerve cells. When this occurs, axons (the parts of the nerve cells that conduct impulses to other cells), don't work as well. Myelin acts as insulation on electrical wires. As more areas or nerves are ...
To compute these markers, a segmentation of lesions in the brain tissues, which are characteristic for MS disease, is needed. In this paper, we propose an unsupervised method for segmenting MS lesions that employs localized trimmed-likelihood estimation (TLE) to model the intensity distributions of...
With the aim of increasing the contrast of the FLAIR MR images with respect to the MS lesions, the proposed method first estimates the fuzzy memberships of brain tissues (i.e., the cerebrospinal fluid (CSF), the normal-appearing brain tissue (NABT), and the lesion). The procedure for ...
Brain lesions—areas of brain tissue that show damage from injury or disease—are the biomarker most widely used to determine multiple sclerosis disease progression. But an innovative new study led by the University at Buffalo strongly suggests that the volume of white matter lesions is neither prop...
three patients displayed only inactive and one patient only active lesions. Of the lesions, 26% were located subcortically, 24% periventricularly, and 9% within the cerebellum. The remaining 41% of the lesions were located in the brain hemispheres, but were neither adjacent to the cortex nor ...
Bladder issues occur when lesions affect nerve signals that control the bladder and urinary function. Symptoms typically include: an increased need to pee an urgent need to pee difficulty starting urination nighttime urination urinary incontinence difficulty emptying the bladder Cognitive changes with MS ...
MS happens when your immune system mistakenly produces inflammation that damages myelin, the protective cover over nerve cells in your brain and spine. You may hear your doctor call this demyelination. The attack causes scars, or lesions, that make it harder for signals to travel between your br...
Automated segmentation of multiple sclerosis (MS) lesions in brain imaging is challenging due to the high variability in lesion characteristics. Based on the generative adversarial network (GAN), we propose a semantic segmentation framework MS-GAN to localize MS lesions in multimodal brain magnetic res...
摘要: A medication that reduces relapse rates in patients with multiple sclerosis (MS) appears to be effective in reducing new brain inflammatory lesions and is well tolerated, according to a study in the December issue of Archives of Neurology, one of the JAMA/Archives journals....
