Advanced Visualization

 

When you close your eyes and visualize an important moment from the past, your brain may use the same eye movement patterns to reconstruct images long after you’ve originally seen them. It may seem like science fiction, but a study published in Cerebral Cortex found evidence of the phenomena.

Why does it seem like when alcohol gets involved, people often exhibit more aggressive behavior thanks to “liquid courage”? According to a group of international researchers, it’s because changes occur in the prefrontal cortex—the area of the brain charged with tempering a person’s aggression—after two drinks.

 

According to a recent study published in JAMA Neurology, memory decline and the potential to develop Alzheimer's disease may increasingly accelerate with age in certain individuals. 

A group of international researchers has discovered two large proteins in the brain that work together in producing its ‘stop’ and ‘go’ functions, much like a children’s game of “Red Light, Green Light.”

We put on our headphones every day, but who considers what allows singers to reach the high notes? Swiss researchers, that’s who.

Novel imaging method allows researchers to view strokes on a molecular level

New research led by scientists at the University of Missouri School of Medicine could accelerate stroke care by using imaging to track enzyme formation inside the brains of stroke victims in real-time, according to results of a study recently published in the Journal of Cerebral Blood Flow and Metabolism.

New molecular MRI tags glow 10,000 times brighter than existing signals

Researchers from Duke University have developed a new type of molecular tag that can enhance MRI signals by up to 10,000 times, according to results of a study published in the March 25 issue of Science Advances.

Multiple sclerosis patients strengthen brains playing video games

Earlier generations of young people were warned that playing video games would turn their brains to mush. New research suggests the exact opposite effect is possible.

3D printing comes of age + more buzz for CAD

The challenge before radiology is clear: boost the value provided by the specialty (and don’t be shy about it). 3D printing offers just one such way of boosting value beyond interpretations.

Optimizing CAD to improve early detection in high-risk breast cancer patients

Using a two-stage classifier to differentiate between malignant or benign mass and non-mass lesions can improve the accuracy of computer-aided diagnosis (CAD) systems and help identify cancer earlier in high-risk patients, according to results of a study published in the March issue of the journal Radiology.

Diabetes exacerbates loss of gray matter, cognitive function in Parkinson’s patients

Diabetes seems to hasten the loss of gray matter in the brains of Parkinson’s patients, and the effect is readily observable in the frontal lobes, where higher mental processes such as decision-making take place, according to a small study published online Feb. 10 in Academic Radiology. 

CTC preferences: What would rads suggest?

CT colonography (CTC), the advanced alternative to standard optical colonoscopy, has seen growing adoption, is apparently preferred by patients, and while there’s continuing research on the questions of costs, some studies find it to be the most cost-effective option. But what do radiologists think?

Global healthcare market for 3D printing expected to eclipse $2.3 billion by 2020

The market for 3D-printing technologies in the healthcare industry is expected to exceed $2.3 billion by the year 2020, according to a new report published online by Allied Market Research.

X-ray vision: Diagnostic accuracy, visual search patterns and 'expert' image interpretation

Diagnostic performance in radiological interpretation increases with experience, though expert-level visual search patterns appear to develop before expert diagnostic accuracy, according to results of a new study published in the journal Radiology.

Survey: Radiologists choose colonoscopy over CTC, but not because of cost

Radiologists prefer colonoscopy over CT colonography (CTC) for colorectal cancer screening due to its effectiveness at detection and immediate biopsy capabilities, according to results of a study published in the February issue of the American Journal of Roentgenology.
