Second, lesions were segmented in the images. Image segmentation was the most important part of the study. The focus of this study was to provide a powerful technique against the noise for this phase. A number of MS candidates appeared. Next, MS lesions were distinguished from the candidates....
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...
The first is a "benign" syndrome in which patients have numerous lesions identified on MRI imaging, but have few -- if any -- symptoms, even decades after their diagnosis. At the opposite end of the spectrum is a condition identified as the Marburg variant of multiple sclerosis, where ...
MRI has become the main paraclinical test in the diagnosis and management of multiple sclerosis. We have demonstrated more than 400 pictures of different typical and atypical MS lesions in this atlas. Each image has a teaching point. New diagnostic criteria and differential diagnosis have been disc...
consent for a brain autopsy and the use of the material and clinical information for research purposes had been obtained by the NBB. Brain biopsies were performed as part of diagnostic evaluation of unclear monofocal lesions that showed atypical MRI findings. None of the study authors were ...
MRI.This diagnostic test uses a combination of large magnets and a computer to make detailed pictures of organs and structures within the body without the use of X-rays. It can find plaques or scarring caused by MS. Generally, a single attack along with certain patterns of changes in brain...
High-field MRI studies have shown that penetrating veins can be detected in most MS lesions using T2∗weighted or susceptibility-weighted imaging. Future studies must address the feasibility of imaging such veins in a clinically practical context. The specificity of this biomarker has been studied ...

MS的治疗目标不再满足于传统的减少复发、延缓残疾进展和减少MRI活动性病灶,而是在控制炎症的同时更要注重远期神经保护,目前已提出了延缓脑萎缩、改善认知功能等更高、更全面的要求27,而后者也已经成为了MS治疗中不可或缺的一部分。 专家介绍 王莉...
