Magnetic resonance imaging (MRI) is an imaging technique which physicians use for the diagnosis and treatment of medical conditions.

Having more children associated with lower stroke risk for women

While some say having lots of kids can make you lose your faculties, a new study suggests otherwise.

Study links ultra-processed food intake to poorer thigh muscle quality

A Radiology study of 615 adults at risk for knee osteoarthritis found that higher ultra-processed food intake was associated with greater fat infiltration in thigh muscles on MRI, a marker of poorer muscle quality. The association remained after adjustment for BMI, was stronger in models using abdominal circumference, and did not differ significantly by sex.

Study reveals brain mechanisms behind post-stroke urinary incontinence

A new USC-led study using functional magnetic resonance imaging (fMRI) reveals the neural mechanisms that contribute to urinary incontinence, a common condition affecting stroke survivors that has a significant impact on their quality of life.

Microplastics found in human bile may be associated with gallstones

Findings show microplastics in bile may trigger cellular senescence, suggesting a link to gallstone disease and highlighting the need for further research.

Study reveals how tau tangles spread from one brain region to another in Alzheimer's

Alzheimer's disease is a progressive neurodegenerative disorder that slowly impairs memory, affects thinking skills, and eventually interferes with daily functioning.

New MRI method tracks transplanted heart stem cells for months

Researchers at the Institute of Biomedical Engineering at the University of Toronto have demonstrated a new way to monitor transplanted stem-cell-derived heart cells using magnetic resonance imaging (MRI).

What happens in the brain on psychedelics? Scientists identify a common circuit pattern

Researchers combined 11 international resting-state fMRI datasets to map how psychedelic drugs reshape brain connectivity across cortical and subcortical circuits. The mega-analysis found a shared signature of stronger coupling between transmodal association networks and unimodal or sensorimotor systems, alongside selective and variable reductions in within-network connectivity.

Newly developed smart molecules offer a safer and more precise approach to cancer care

Researchers at NYU Abu Dhabi have developed smart molecules that can both detect and treat cancer, offering a safer and more precise approach to care.

Navigated TMS significantly boosts combat PTSD recovery rates

An advanced version of a procedure using magnetic fields to stimulate brain nerve cells in treating depression was significantly effective for 85% of active military and veterans suffering from combat post-traumatic stress disorder enrolled in a recent study, when added to psychotherapy.

How the brain constructs precise perception of time

How does Jannik Sinner manage to hit the ball at exactly the right moment, with remarkable precision?

Study introduces biomarker to characterize aggressiveness of brain tumors

Researchers from the Biomedical Data Science Laboratory (BDSLab) at the ITACA Institute of the Universitat Politècnica de València have developed a new method based on magnetic resonance imaging that enables objective quantification of the growth of the most aggressive brain tumours, particularly glioblastoma.

Novel MRI technique reveals sleep-driven brain cleansing mechanisms

Sleep helps the brain to cleanse itself – and now this process can be measured in humans entirely non-invasively.

Dual imaging reveals hidden causes of heart attacks without blockages

When Ashley Perlow felt a sharp pain shoot across her chest and into both wrists, she didn't think it could be a heart attack. She was 36, a new mom, and otherwise healthy.

Study links atrial fibrillation to poorer brain clearance and cognitive decline

Researchers found that people with atrial fibrillation had lower MRI-based glymphatic activity and poorer cognitive performance than healthy controls, with the greatest impairment seen in non-paroxysmal AF. In patients who underwent catheter ablation, glymphatic activity improved after sinus rhythm was restored, suggesting a possible link between heart rhythm, brain waste clearance, and cognition.

Temporary heart pump before PCI shows no significant benefit

The first randomized trial to test whether adding a small, temporary pump to allow the heart to rest and intentionally delaying percutaneous coronary intervention (PCI), also known as coronary angioplasty, for 30 minutes to reduce heart damage compared with standard immediate PCI in patients with heart attacks at risk for a large amount of heart damage found no significant difference between the two groups, the study's primary endpoint. The research was presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Can AI chatbots help brain tumor patients understand their care?

Integrating LLMs in brain tumor care could enhance patient understanding, but requires strict oversight to manage risks and ensure reliable information.

Scientists discover similarities in brain aging between mice and humans

By scanning the brains of mice throughout their lifespans, scientists at Columbia's Zuckerman Institute and the University of Texas at Dallas have discovered that the human brain is not unique in how it changes with age.

Scientists turn red blood cells into long-lasting drug and imaging carriers in mice

A new preclinical study shows that red blood cells can be tagged in vivo and used as long-lasting carriers for imaging agents and therapies, opening a new route for safer drug delivery and vascular imaging.

Brain lesions in Down syndrome show unexpected reversible changes

What has long been interpreted as permanent and irreversible vascular damage may not be exclusively so.

Study finds GLP-1 medicines cut fat while preserving muscle function

Researchers found that GLP-1 medicines caused weight loss mainly through fat reduction, with only modest decreases in absolute muscle mass and no disproportionate loss of muscle function. In mice, physical performance improved, while in a small 12-week human pilot trial, strength was preserved despite reduced thigh muscle size.
