Aussie researchers have found protocoled 3D laser scanning to be as good as noncontrast MRI for assessing breast volume, according to a small study running in the April edition of Annals of Plastic Surgery. 

When functional MRI (fMRI) was developed in the early 1990s, it was the latest in a long line of imaging modalities that allowed scientists and researchers to use changes in blood oxygenation and flow to infer neural activity. Since the seminal research paper was published by Seiji Ogawa, PhD—then working at AT&T Bell Laboratories—fMRI has provided insight in how the brain forms memories and processes pain, emotion, or language.

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.

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.

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.
