Advanced Visualization

 

Researchers, led by scientists at the University of Cambridge, have found a correlation between interconnectivity of brain regions and individual intelligence using brain MRI, according to a study published online in Neuron.

Researchers explored using MRI to distinguish age-related changes and as a tool to evaluated aging thigh muscles. The study used four quantitative MRI techniques: intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI), diffusion-tensor imaging (DTI), multiecho Dixon water-fat imaging and dynamic contrast material–enhanced (DCE) MR imaging.

New technology developed at New York’s Binghamton University could change the way clinicians detect heart disease with MRI scans, research published in the journal Colloid and Surfaces B: Biointerfaces suggests.

Around this time of year, people are reminded it’s better to give than receive. According to recent research using functional MRI (fMRI) to examine brain function, this is true when it comes to giving thanks. Gratitude may be good for mental health and increase overall feelings of altruism.

Computer tomography (CT) has produced stunning images and improved diagnosis and treatment of myriad health complications. A German research team has developed an imaging technique called nano-CT that produces images at resolutions up to 100 nanometers, a marketed improvement from the 500 nm in traditional CT methods.

Researchers at Massachusetts General Hospital’s Wellman Center for Photomedicine have used coherent anti-Stokes Raman Scatterings (CARS) microscopy to improve detection of melanoma, the most common skin cancer.

Paralyzed ALS patients use imaging to communicate

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. 

Affordable 3D-printed organ models created by startup, now available for medical training

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

Mild brain-impact changes: Easy come, easy go (as long as players take enough time off)

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.

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.

Diluted gadolinium works well at minimizing ghosting artifacts on liver MRI

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. 

Contrast-enhanced sonography a ‘sound’ alternative in pediatric advanced imaging

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. 

New technology creates 2D and 3D images of children with musculoskeletal conditions

A new imaging system has been installed at the Orthopaedic Institute for Children (OIC), now providing the most precise and safest way to diagnose musculoskeletal conditions in children.
