Multiple Sclerosis Lesion Activity Segmentation with Attention-Guided Two-Path CNNs [PDF]
arXiv, 2020 Multiple sclerosis is an inflammatory autoimmune demyelinating disease that is characterized by lesions in the central nervous system. Typically, magnetic resonance imaging (MRI) is used for tracking disease progression. Automatic image processing methods can be used to segment lesions and derive quantitative lesion parameters.

Multiple Sclerosis Lesions Segmentation using Attention-Based CNNs in FLAIR Images [PDF]
arXiv, 2022 Objective: Multiple Sclerosis (MS) is an autoimmune, and demyelinating disease that leads to lesions in the central nervous system. This disease can be tracked and diagnosed using Magnetic Resonance Imaging (MRI). Up to now a multitude of multimodality automatic biomedical approaches is used to segment lesions which are not beneficial for patients in ...

Coexistence of Multiple Sclerosis and Brain Tumor: An Uncommon Diagnostic Challenge
Advanced Biomedical Research, 2017 Nonneoplastic demyelinating processes of the brain with mass effect on magnetic resonance imaging can cause diagnostic difficulties. It requires differential diagnosis between the tumefactive demyelinating lesion and the coexistence of neoplasm.

Neuron Signal Propagation Analysis of Cytokine-Storm induced Demyelination [PDF]
arXiv, 2021 The COVID-19 pandemic has shaken the world unprecedentedly, where it has affected the vast global population both socially and economically. The pandemic has also opened our eyes to the many threats that novel virus infections can pose for humanity. While numerous unknowns are being investigated in terms of the distributed damage that the virus can do ...

Glial grafting for demyelinating disease [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2005 Remyelination of demyelinated central nervous system (CNS) axons is considered as a potential treatment for multiple sclerosis, and it has been achieved in experimental models of demyelination by transplantation of pro-myelinating cells. However, the experiments undertaken have not addressed the need for tissue-type matching in order to achieve graft ...

What dominates the time dependence of diffusion transverse to axons: Intra- or extra-axonal water? [PDF]
, 2017 Brownian motion of water molecules provides an essential length scale, the diffusion length, commensurate with cell dimensions in biological tissues. Measuring the diffusion coefficient as a function of diffusion time makes in vivo diffusion MRI uniquely sensitive to the cellular features about three orders of magnitude below imaging resolution ...

The virology of demyelinating diseases [PDF]
Annals of Neurology, 1994 Infectious agents have been postulated as causes of multiple sclerosis for over a century. The possible role of a virus or viruses is supported by data that (1) a childhood exposure is involved and "viral" infections may precipitate exacerbations of disease, (2) experimental infections in animals and natural infections in humans can cause diseases with

Inflammatory demyelinating polyneuropathy versus leptomeningeal disease following Ipilimumab
Journal for ImmunoTherapy of Cancer, 2018 Background Ipilimumab is an FDA-approved anti-CTLA-4 monoclonal antibody used in treatment of metastatic melanoma. We present an unusual neurological complication of Ipilimumab therapy and the diagnostic dilemma it caused. Case presentation A 42 year old
