Drawing from previous neuroimaging research grounded in functional MRI, researchers have used functional near-infrared spectroscopy (fNIRS) to help patients who have intact cognitive and emotional function but are “locked in” by total motor paralysis—as by Lou Gehrig’s disease—to communicate just by thinking. 

A new startup launched today making their 3D-printed organ models for surgical planning, biomedical research and education available tor the training community.

Concussions or no, collegiate football players who experience repetitive head impacts during a single season sustain alterations to the white matter in their brains. The good news: The damage tends to disappear on diffusion tensor MRI after six months of rest, suggesting remission, according to a small prospective study published online Jan. 14 in Brain Imaging and Behavior.

Comparing two methods of administering gadolinium-based contrast for MRI exams head to head, researchers have found that dilution with saline is better than a reduced injection rate at minimizing arterial-phase artifacts. 

Off-label use of contrast-enhanced ultrasound (CEUS) may be the best advanced-imaging choice—safe, accurate and cost-effective as compared to guideline-recommended CT and MRI—for examining children in many instances, according to a British study published online Dec. 13 in the American Journal of Roentgenology.

Researchers develop graphene-based detection of brain cancer

Graphene’s resume is impressive: It’s 200 times stronger than steel, conducts heat and electricity with the utmost efficiency, and is the thinnest material known to man. The two-dimensional compound is made of a hexagonal lattice of carbon atoms, with applications ranging from solar power to tennis rackets.

Novel PET compound upends the field at detecting Alzheimer’s-associated amyloid

Washington University researchers say they have developed a novel PET tracer that is significantly better than FDA-approved compounds at detecting amyloid clusters in patients with suspected Alzheimer’s disease. 

Continuous imaging shows cells during limb regeneration

Regeneration of limbs may be restricted to lizards and crustaceans, but science is no less interested in studying just how cells accomplish the amazing feat. For the first time, researchers have been able to record just how epidermal cells act during regrowth after amputation.
