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.

Small protein discovered that specifically recognizes tumors responding to chemotherapy

A technique that specifically "tags" tumors responding to chemotherapy may offer a new strategy for determining a cancer treatment's effectiveness within days of starting treatment, according to a new study by Vanderbilt-Ingram Cancer Center investigators.

Zero-field remote detection of NMR with a microfabricated atomic magnetometer

A super-sensitive mini-sensor developed at the National Institute of Standards and Technology (NIST) can detect nuclear magnetic resonance (NMR) in tiny samples of fluids flowing through a novel microchip.

Study identifies patterns of brain activation linked to the formation of long-term memories

Researchers at New York University and Israel's Weizmann Institute of Science have identified patterns of brain activation linked to the formation of long-term memories.

Brain-scanning technology helps trace source of emotions in brain

First came direct marketing, then focus groups. Now, advertisers, with the help of neuroscientists, are closing in on the holy grail: mind reading.

CT scan can harm kidneys, but cheap drug can help

As more and more Americans undergo CT scans and other medical imaging scans involving intense X-rays, a new study suggests that many of them should take a pre-scan drug that could protect their kidneys from damage.

New non-invasive imaging method for diagnosing osteoarthritis

Researchers at New York University and Tel Aviv University have developed a non-invasive imaging method that can be used to diagnose and monitor a number of diseases, including osteoarthritis and inter-vertebral disc degeneration, in their early stages.

Poor recognition of 'self' found in high functioning people with autism

Contrary to popular notions, people at the high end of the autism spectrum disorder continuum suffer most from an inability to model "self" rather than impaired ability to respond to others, said Baylor College of Medicine researchers in a report that appear in the journal Neuron.

Brain disturbances in chronic pain

People with unrelenting pain don't only suffer from the non-stop sensation of throbbing pain.

Brain study suggests way to measure, treat autism

Researchers have pinpointed subtle deficits in the brains of people with autism spectrum disorder (ASD) that they say could aid more precise diagnoses and perhaps improve treatment of ASD.

Chemists track how amantadine drug changes, blocks flu virus

An anti-virus drug attacks influenza A by changing the motion and structure of a proton channel necessary for the virus to infect healthy cells, according to a recently published research paper by two Iowa State University chemists.

Video games activate reward regions of brain in men more than women

Allan Reiss, MD, and his colleagues have a pretty good idea why your husband or boyfriend can't put down the Halo 3. In a first-of-its-kind imaging study, the Stanford University School of Medicine researchers have shown that the part of the brain that generates rewarding feelings is more activated in men than women during video-game play.

Subconscious signals can trigger drug craving

Using a brain imaging technology called functional magnetic resonance imaging (fMRI), scientists have discovered that cocaine-related images trigger the emotional centers of the brains of patients addicted to drugs even when the subjects are unaware they've seen anything.

Why is scratching so nice?

In the first study to use imaging technology to see what goes on in the brain when we scratch, researchers at Wake Forest University Baptist Medical Center have uncovered new clues about why scratching may be so relieving - and why it can be hard to stop. The work is reported online in the Journal of Investigative Dermatology and will appear in a future print issue.
