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.

PET staging charts illustrate Alzheimer's progression, amyloid development

A new study conducted by a team of researchers led by Michel Grothe of the German Center for Neurodegenerative Diseases in Rostock, Germany, announced the development of a four-stage model of regional amyloid beta (Aβ) protein deposition that can be found in patients with Alzheimer's, according to an article by Alzforum. 

Gestational age matters in brain development at birth, but preemies can catch up in childhood

Longer gestation during normal pregnancy is associated with significantly greater development of white matter in babies’ brains. However, similar associations are no longer present by the time children are 8 years old. The lack may confirm that white-matter development in the brains of preemies tends to catch up as these children grow.

FDA greenlights Siemens Healthineers’ 7T MRI for clinical use

In a first, the FDA has cleared a powerful 7-tesla MRI scanner for clinical use.

fMRI shows how abbreviated sleep bothers the brain, messes with mood

The National Sleep Foundation recommends seven to nine hours of shuteye per night for adults between 26 and 64. Using functional MRI, researchers at Japan’s National Institute of Mental Health in Tokyo have shown why getting less often leads to bad moods and poor emotional health.

Microbubble ultrasound, perfusion software combine to check ablation of liver lesions

Following percutaneous interventions for malignant liver lesions, patients are ably assessed with a combination of contrast-enhanced ultrasound (CEUS) and perfusion-imaging software, according to the authors of a study published online September 25 in Ultraschall in der Medizin/European Journal of Ultrasound.

Bone-removal algorithm opens a window into trauma-induced brain bleeds

Researchers have demonstrated an automated bone-removal algorithm that works with dual-energy CT to let physicians see, unobstructed by the skull, what’s going on in the brains of patients with intracranial hemorrhage following head trauma.

Pain panel: Don’t use brain imaging as a medicolegal ‘lie detector’

A task force convened by the International Association for the Study of Pain is warning against the use of neuroimaging in legal cases involving patients who claim they’re living with chronic pain.

Bird brains: CT links development of avian skulls to baby dinos

A new study featuring 3D CT imaging has shown how bird skulls evolve differently than relatives and ancestors. Instead, they develop more like young dinosaurs and crocodiles.

Functional MRI shows cognitive rehab aiding mildly impaired elderly minds

The cognitive therapy called Attention Process Training-II (APT-II) provides worthwhile benefits to elderly patients with mild cognitive impairment (MCI) who have cerebral small vessel disease and are therefore at heightened risk for dementia.

Ultrasound, other tests point to chronic shoulder problems for swimmers

The finding isn’t likely to sway Katie Ledecky or other swimmers from training for the 2020 Summer Olympics in Tokyo, but a small study at Henry Ford Health System in Detroit has shown that long competitive careers in the pool can saddle these athletes with chronically reduced mechanical properties in muscles and tendons of the shoulder, heightening the likelihood of rotator cuff damage.
