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.

Q&A: Aspect Imaging CEO sees big potential in smaller MRI machines

Aspect Imaging, a design and producer of MRI systems, have developed an MRI machine that is more compact than many contemporary machines.

Vascular disruption—not amyloid accumulation—is Alzheimer’s first observable brain change

A new analysis of big data largely based on thousands of MR and PET images has shown that changes in blood flow to and within the brain precede amyloid build-up in Alzheimer’s patients. 

Concussions alter brains well past point of full-function regain

Amplifying research from earlier this year showing that the anatomic effects of traumatic brain injury persist long after observable symptoms subside—potentially long enough to increase risk for Alzheimer’s—a new diffusion MRI study has shown white matter changes in the brains of athletes six months after a concussion event.  

The U.S. healthcare system is damaging to environment. So now what?

Here’s a not-so-fun thought: our healthcare system is having a bad effect on the environment. It’s having a really bad effect, actually. 

fMRI shows marijuana users’ brains light up less over nondrug rewards

A new fMRI study has shown how marijuana use dulls neural activity in the nucleus accumbens (NAcc), a key part of the brain’s “reward pathway.” The imaging also captured the effect associating with sluggish anticipatory excitement over the promise of nondrug rewards such as money. 

Literature review suggests most fMRI findings have been unreliable at best

A new analysis of the literature on fMRI suggests that a shortcoming in the most popular software systems used to evaluate the imaging data—SPM, FSL and AFNI—may have caused all three to produce false positive findings at a 70 percent clip from 1992 to 2015. 

Gray matter differences imaged in diabetic teens

Prior research has established that teenagers with type 2 diabetes have different gray-matter volumes and poorer cognitive function than their nondiabetic peers. A new MRI-based study at Cincinnati Children's Hospital Medical Center has imaged the particular regions in which the differences occur. 

Diffusion MR proves adept at predicting concussion outcomes

Diffusion tensor MRI can be used to separate concussion patients who are likely to fully recover within a year from those who are likely to suffer longer-term effects, pointing to the most appropriate treatment pathways for each. 

Sheryl Crow named Hologic's national celebrity spokesperson for breast cancer educational campaign

Hologic, a developer, manufacturer and supplier of diagnostic products, medical imaging systems and surgical products, has announced a partnership with singer, songwriter and breast cancer survivor Sheryl Crow.

MRI may illuminate new avenues for schizophrenia treatment

Using MRI with covariance analysis, researchers have revealed tissue increases over time in the brains of patients with schizophrenia. The increases suggest these brains may be compensating for lost capacity and perhaps trying to protect themselves against further damage.
