Magnetic Resonance Imaging (MRI) News and Research

RSS

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord. Also called: Magnetic resonance imaging, NMR, Nuclear magnetic resonance.

Brain volume may be used as an early detection system for dementia

Reduced volume, or atrophy, in parts of the brain known as the amygdala and hippocampus may predict which cognitively healthy elderly people will develop dementia over a six-year period, according to a study in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

New techniques are able to detect and monitor Alzheimer's disease

The search for new measures, or "biomarkers," to detect Alzheimer's disease (AD) before signs of memory loss appear has advanced an important step in a study by researchers at Washington University in St. Louis, MO, and the University of Pittsburgh.

Chronic pain sufferers may be able to reduce pain levels by studying their own live brain images

Chronic pain sufferers may be able to reduce pain levels by studying their own live brain images, researchers at the Stanford University School of Medicine report in a new study.

It's all in the mind so think that pain away

According to U.S. researchers chronic discomfort can be reduced by brain manipulation and people in chronic pain can "think away" their suffering by learning to manipulate the activity of the brain.

Surprising autism finding

New brain imaging research at the University of North Carolina at Chapel Hill indicates that when people with autism look at a face, activity in the brain area that responds is similar to that of people without autism.

Brain enlargement may indicate autism

Magnetic resonance imaging (MRI) has found evidence of brain enlargement in a relatively large sample of children with autism, compared with children who do not have the disorder, according to a study in the December issue of Archives of General Psychiatry.

Men are from Mars, women are from Venus - when it comes to brains!

The comedians are right. The science proves it. A man's brain and a woman's brain really do work differently.

New technique reveals brain function

Researchers have a relatively good understanding of "where" and "when" the brain edits incoming information; the question is "how" does this happen. It may be that researchers at the University of Bergen have found the answer.

Perk up that memory with some caffeine

It seems brain scans confirm what coffee drinkers already know - that caffeine gives the brain a boost.

Amygdala activation to interpersonal threat can be specifically linked to the severity of social anxiety symptoms

People suffering generalised social phobia experience increased brain activity when confronted with threatening faces or frightening social situations, new research shows.

Stenting of the carotid artery significantly improves cognitive speed

Stenting of the carotid artery significantly improves cognitive speed and may improve memory function in some patients, according to research presented at the annual meeting of the Radiological Society of North America (RSNA).

Updated guidelines for diagnosing multiple sclerosis

An international panel of neurologists has updated the current guidelines for diagnosing multiple sclerosis (MS), strengthening the role of magnetic resonance imaging (MRI).

Music training may change the brain

New research shows that the special training of music conductors seems to enhance the way their senses work together - enabling them to quickly tell who played a wrong note, for example. Scientists hope the research will lead to new discoveries about how music training may change the brain.

Visibility, visual awareness, and visual masking of simple unattended targets are confined to areas in the occipital cortex beyond human V1/V2

Dartmouth professor of psychological and brain sciences Peter Tse has published new results in his on-going investigation of the brain and how it transforms visual stimuli into conscious experience.

Early changes in the oxygenation of the skin may help predict foot disease in diabetes patients

Foot ulcerations are one of the most serious complications of diabetes, resulting in more than 80,000 lower-leg amputations each year in the U.S. alone.

Gender affects the way a person's brain responds to humor

Need more evidence that men and women are different? Look no further than the Sunday funnies. According to a new Stanford University School of Medicine study, gender affects the way a person's brain responds to humor.

Meditation associated with increased cortical thickness

Meditation is known to alter resting brain patterns, suggesting long lasting brain changes, but a new study by researchers from Yale, Harvard, Massachusetts General Hospital, and the Massachusetts Institute of Technology shows meditation also is associated with increased cortical thickness.

MRI measurements of scar tissue accurately predict the risk of arrhythmia-related sudden death

Using magnetic resonance imaging (MRI) scans of the heart wall, researchers at Johns Hopkins have found that people whose muscle wall thickness contained more than 25 percent scar tissue were approximately nine times more likely to test positive for a fast and dangerous heart rhythm known as ventricular arrhythmia.

Functional diffusion map to help predict brain tumor outcomes

A special type of MRI scan that measures the movement of water molecules through the brain can help doctors determine halfway through treatment whether it will successfully shrink the tumor or a patient's cancer will continue to grow, a new study shows.

How the brain tracks time is essential to understanding all its functions

The brain is a "time machine," assert Duke neuroscientists Catalin Buhusi and Warren Meck. And understanding how the brain tracks time is essential to understanding all its functions. The brain's internal clocks coordinate a vast array of activities from communicating, to orchestrating movement, to getting food, they said.
