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.

3D scanning system captures T. rex, bites into upfront costs

3D imaging is an exciting niche in the field of medical imaging. One obstacle to further exploration, though, is the hefty upfront costs to acquire the necessary hardware and software. Researchers have developed a promising 3D imaging system that costs a few hundred dollars—a mere fraction of the cost of many CT-based systems.

Prostate-specific PET/CT finds elusive cancers, fine-tunes care management

A high proportion of prostate cancer patients have their care pathways changed after being scanned with PET/CT enhanced by the injected radiotracer gallium-68 (Ga-68) and prostate-specific membrane antigen (PSMA).

Screening bone CT helps avoid osteoporosis fractures

By combining virtual bone-strength testing with standard bone mineral density testing—the former using quantitative CT, the latter with dual-energy x-ray absorptiometry (DXA)—clinicians can help postmenopausal women ward off a substantial number of painful fragility fractures.

Computer-assisted CT colonography performs well, gets reimbursed

CT colonography aided by computer detection has proven sharp at finding colorectal polyps 6 mm or larger—and at earning reimbursement—in routine clinical practice, where it also had an acceptable false-positive rate, according to a study running in the June edition of the American Journal of Roentgenology.

When it comes to cybersecurity, imaging departments must prepare for the worst

“WannaCry,” the most recent ransomware attack in the United Kingdom, was yet another reminder of how dependent modern healthcare is on networked technology. The National Health Service experienced ambulances piling up outside hospitals, appointments were canceled, surgeries were delayed and there was the frightening possibility that patient records could be deleted unless a ransom was paid.

More evidence of preterm birth affecting brain development in adolescents

Teenagers who came into the world as “preemies” have altered brain connectivity on MRI, as well as differences in cognitive function, compared with their peers who spent the full nine months in utero.

MRI shows summer reading physically increases children’s brain power

Harvard and MIT researchers have found that the more reading schoolkids do over the summer, the more their brains develop—and those who struggle with reading and come from low-income households stand to make the most impressive gains.

AI-powered microscope has no lens yet ‘sees’ nanoparticles for pathologists

Artificial intelligence is driving change into pathology as well as radiology. In Canada, for example, researchers have developed a lens-less microscope that uses algorithms based on mathematical models of light to produce large-scale slide images in 3D.

SNMMI partnering with NDSC to disseminate appropriate-use criteria

Clinicians referring patients for imaging with nuclear and molecular modalities will soon be able to do so with ready access to utilization assistance that’s based on appropriate-use criteria developed by the Society of Nuclear Medicine and Molecular Imaging (SNMMI).

MRI as accurate as CT for Crohn’s disease detection, management

Both MRI and CT are highly accurate when it comes to detecting Crohn’s disease in the small intestine, and MRI can be the go-to modality when radiation exposure is an issue—as can be the case due to the repetitive imaging that’s often indicated for managing this chronic inflammatory bowel disease.
