Image: Amyloid beta oligomers bind to neurons and are distinct from amyloid plaques. Brain sections from an aged Alzheimer’s mouse model were probed with antibodies against Abeta oligomers (568-NU4, red) and amyloid plaques (ThioS, green). Images demonstrate that Abeta oligomers (568-NU4) are often associated with, yet distinct from, amyloid plaques (ThioS). Where both amlyoid plaques (green) and A-beta oligomers (red) overlap, shows up as yellow. NU4 labelling is more abundant than the ThioS staining. Data supports the notion that NU4 thus affords an excellent targeting antibody for the development of an amyloid beta oligomer-specific MRI probe that is distinct from currently available plaque probes (Photo courtesy of an adaption from Viola et al, Nature Nanotechnology, 2014).

MRI Probe Combined with Magnetic Nanostructure and Antibody can Detect Alzheimer’s Disease Early

A noninvasive MRI application has been designed that can detect the Alzheimer’s disease in a living animal, well before typical Alzheimer’s symptoms appear. The researchers created an MRI probe that combines a magnetic nanostructure with an antibody that searches for the amyloid beta brain toxins responsible for onset of the disease. The accumulated toxins, because of the associated magnetic nanostructures, are revealed as dark areas in MRI scans of the brain.  More...

New Functional MR Technique to Help Improve Understanding of Spinal Cord Injuries and Diseases

Researchers at the Vanderbilt University Institute of Imaging Science have demonstrated that resting state networks, similar to those in the brain, also exist in the human spinal cord. Changes to the resting state networks in the brain have been linked to various disorders including memory problems during aging.  More...

fMRI Scanning Shows Transcranial Direct Current Stimulation Enhances Motor Learning Ability After Stroke

Neuro-rehabilitation techniques such as physical therapy and occupational therapy help hemaparetic stroke patients dealing with loss of motor skills on one side of their body, to regain some of their motor functions after a cerebrovascular accident.  More...

Image: Structural connectomes (top two rows) and corresponding florbetapir PET images (bottom two rows) in four patients with normal cognition (NC) with the lowest whole cortex amyloid burden (left) and the four patients with AD with the highest whole cortex amyloid burden (right) focused on the composite regions used in connectome versus amyloid analysis. Nodes represent the centroids of the FreeSurfer parcellations in the frontal (red), cingulate (green), temporal (light blue), and parietal (dark blue) regions. This is only a schematic intended to show the concepts and is not intended to show any visually discernible generalizable difference between the patients with NC and those with AD. Structural network metrics provide more sensitive information about the connectome than are apparent through visualization alone (Photo courtesy of RSNA).

Diffusion Tensor MRI Reveals Brain Connection Failure in Early Alzheimer’s Disease

Diffusion tensor imaging has been shown to reveal changes in white matter connections in the brains of patients with early Alzheimer’s disease.   More...
