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.

Misidentified sniffs may point to early-stage Alzheimer’s

Mayo Clinic researchers have found a correlation between neuroimaging biomarkers of Alzheimer’s disease and results from a literal smell test: If at-risk older folks are losing their sense of smell, they’re more likely to be developing the disease than their well-smelling peers. 

Smokers’ brains show cognitive avoidance toward visual quitting aids

A small but fascinating functional MRI study has shown how smokers may stubbornly harden their minds against the psychological quitting-assistance technique known as aversive conditioning. 

3D printed 'bionic skin' could aid in health monitoring

A revolutionary process for 3D printing stretchable electronic sensory devices that could be used to produce real human skin has recently been developed by researchers at the University of Minnesota.

AI will change radiology—but it won’t replace the radiologist

Decreased costs of computing power and virtually infinite cloud storage capacity have created a fertile environment for artificial intelligence (AI) to disrupt industries across the globe. Computers won’t replace radiologists in the next 10, 20 or 30 years, but I do believe increasingly large parts of the job will be automated—and it may be up to radiologists to carve out space for themselves.

Puberty changes the brain in sex-specific ways

New neuroimaging-based research at the University of Southern California has shown how, over time, the developing pubescent brain changes in distinct ways between boys and girls. 

Virtual reality: Coming to an imaging provider near you?

Blu-Ray, 3D TVs and now virtual reality—three technologies that were each hailed at one point as the next big thing in consumer entertainment. One became ubiquitous, one all but disappeared and the jury’s still out on whether or not virtual reality (VR) is here to stay. 

Matching CT image data with patient photos, FBI researchers caution on privacy

Facial images extracted from publicly available radiology scans—think of head CT scans stored in open-access medical image repositories for research and education—are fairly easy to match with patients’ photos, raising concerns over privacy.

High-rez finger MRI may point way to burgeoning extremity uses for 7T

European researchers have demonstrated a dedicated setup for fast-acquisition, ultrahigh-resolution in vivo MRI of the finger, according to a study posted online in Magnetic Resonance in Medicine. 

fMRI shows reorganization of neural circuits to improve cochlear implantation

Two scientists used brain-imaging techniques to visualize the brain’s activity and view the reorganization of brain circuits while people start to lose their hearing. This allowed them to predict the success or failure of a cochlear implant amongst people who have become profoundly deaf in their adult life.

Lack of physical activity could weaken bones in teens

University of British Columbia researchers and the Centre for Hip Health and Mobility researchers used high-resolution peripheral quantitative computed tomography (HR-pQCT) and found that teens who are inactive tend to have weaker bones than those who are physically active.
