White matter microstructure and Alzheimer’s disease pathology Insights from tractography and PET
A presentation by Alexa Pichet Binette
(small technical problem between minutes 01:40 and 04:00)
Amyloid-beta and tau proteins are the main pathological hallmarks of Alzheimer’s disease (AD), which start to deposit in the brain years before any clinical symptoms. Both proteins tend to accumulate in regions that are connected by well-defined anatomical white matter bundles. However, measures of white matter microstructure in relation to AD pathology are not often incorporated in studies. The first part of the presentation will give an overview of the current state of knowledge with regards to the links between pathology and diffusion-based measures of white matter, with a particular focus on...

Concussion Biomarkers: Novel imaging and advanced statistics
Просмотров 2453 года назад
A presentation by Guido Guberman, MD/PhD candidate at McGill University. Despite major investments in scientific and clinical research, no significant progress in concussion pharmacotherapy has been achieved to date. Concussion heterogeneity has been identified as a major obstacle in advancing concussion care. Concussions are extensively heterogeneous in terms of patient characteristics, neurop...
Utility of Tractography and Connectomics in Neurosurgery Why Tracking Matters
Просмотров 4033 года назад
A presentation by Sami Obaid, MD, CM, FRCSC, Neurosurgeon, PhD candidate, University of Montreal The use of DWI-derived tractography has recently emerged as a novel technique to guide surgical resections in epilepsy and oncological neurosurgery. Tractography is a useful adjunct in localizing white matter tracts intraoperatively and allows sparing of functional connections for both tumor-related...
Diffusion MRI in Multiple Sclerosis and Why it Matters
Просмотров 4963 года назад
A presentation by Ann-Marie Beaudoin MD, Multiple sclerosis (MS) is an autoimmune neurodegenerative disease of the central nervous system characterized by inflammation, demyelination, gliosis, axonal loss, and, atrophy. Conventional MRI is sensitive to white matter changes in MS, but it lacks specificity for the underlying pathological processes. Advanced diffusion MRI methods have the potentia...
Quantitative MRI to assess tissue damage in multiple sclerosis
Просмотров 3333 года назад
A presentation by Tim Sinnecker. Quantitative MRI aims to provide physical or chemical variables that can be compared between tissue regions and among subjects. It hence provides a way to assess pathological changes of the central nervous system that may precede or accompany volumetric and/or focal alterations of the brain. Here we describe and discuss recent developments in the field with focu...
The role of White Matter in Alzheimer Disease
Просмотров 4643 года назад
Major changes of the white matter in Alzheimer’s disease (AD) patients have been observed for decades. White matter integrity is however rarely included as a biomarker in models of AD pathological cascade. This presentation will review white matter regions affected by the pathology in comparison to mild cognitive impairment. The fact that white matter changes occur early, in pre-symptomatic pha...
MRI biomarkers for the spinal cord, webinar with Dr. Julien Cohen-Adad.
Просмотров 3443 года назад
Neuroimaging MRI biomarkers include volumetric measures, microstructure imaging such as diffusion-weighted imaging and magnetization transfer, and functional MRI. These biomarkers nicely complement clinical indices and provide objective means to monitor disease evolution in patients. While being very popular in the brain, MRI biomarkers have been slow to translate to the spinal cord because of ...
A Brain Odyssey: Challenges and solutions for tractography in clinical settings
Просмотров 2743 года назад
Diffusion magnetic resonance imaging tractography is becoming increasingly popular in a variety of medical research fields. In the past two decades, tractography has become an incredible tool to investigate the structural connectivity of the brain. However, the number of processing steps and modeling complexity is sometimes more problematic than one could expect. While processing and analysis i...
Visualizing blood vessel structure and function in the human brain
Просмотров 2604 года назад
Presentation by Kevin Wittingstall, PhD and professor at University of Sherbrooke. Accumulating evidence indicates that changes in the brains vascular system are amongst the earliest to appear in several neurodegenerative disorders. Despite this, few methods exist for visualizing, identifying and quantifying cerebral blood vessels in humans. In this talk, I will discuss our recent attempts at r...
