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

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.

MR-guided brain ultrasound helps rouse coma patient back to consciousness

Neuroscience researchers and clinicians at UCLA have used MR-guided ultrasound to help rouse a recovering coma patient to a more alert state of consciousness. 

New zinc-focused MRI technique can ID cancerous prostate tissue

Distinguishing between healthy and cancerous cells just might be the biggest hurdle in cancer care physicians have encountered. A new MRI technique developed by radiologists at UT Southwestern Medical Center in Dallas have fixed that problem using zinc.

fMRI brain study unpacks, predicts sentence-level verbal expression

Researchers have used functional MRI (fMRI) to come up with a way to predict neural patterns produced by words within sentences. Building on previous studies that focused on single words lighting up parts of the brain, the team correctly anticipated brain-activity patterns at the sentence level to the tune of 70 percent accuracy, on average.

fMRI shows kids’ brains lighting up for unhealthy foods pushed on TV

Neuroscience isn’t needed to know that food commercials influence children’s choices of what to eat and how determinedly to demand it. If those ads for sugary, fatty, high-sodium, low-fiber and fun-to-eat products didn’t work, the food and beverage industry wouldn’t be spending $2 billion per year to create and place them.  

Study: More radiotherapy can cut mortality risk in half

Researchers have found patients with high-risk prostate cancer who are treated with a high portion of radical local treatment (radiotherapy or prostatectomy) have half the mortality risk of those who were treated with the lowest proportion.

Study uses MRI to show thirst is an anticipatory reflex

For the first time ever, researchers say they’ve uncovered the mechanism for short-term thirst and thirst quenching, according to a new article in the journal Nature.

 
When teaching radiology, don’t forget to embrace the unknown

Most articles in today’s radiology journals focus on specific case studies or problems facing the industry. A recent editorial published in the Journal of the American College of Radiology, however, really caught my eye by taking a deeper, more philosophical approach.

4D lung imaging platform gives clearer vision for early detection

Professor Andreas Fouras of Monash University has developed a four-dimensional lung scanning technology platform, helping physicians to detect abnormal lung functions early, reports News Medical.

PET imaging gives insight into a brain with depression

Scientists from the RIKEN Center for Life Science Technology (CLST) have developed a new PET scan that is able to analyze neuron proliferation in the brain's subventricular and subgranular zones of the hippocampal dentate gyrus, the areas most affected by depression.

Imaging tool shows oxygen in human tissue like never before

Oxygen, the air we breathe and the foundation of life, remains mysterious in terms of seeing it working through our tissues. That is until researchers developed a new tool to show us just how oxygen travels to our tissue.
