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.

Stroke in the young on the rise: Study

A new study has revealed that more children and young adults in the U.S. are having strokes. Researchers speculate that unhealthy lifestyles could be a likely contributor.

Magnetic resonance imaging may predict survival in patients with advanced rectal cancer

A new study has shown that magnetic resonance imaging (MRI) used to evaluate responses to pre-surgery (neo-adjuvant) chemotherapy or radiation may predict survival among patients with advanced rectal cancer.

Scientists discover nanoparticles can disrupt intracellular transport pathways

Scientists at the Centre of Cancer Biomedicine at the Norwegian Radium Hospital are the first to show that uptake and accumulation of nanoparticles in cells can disrupt important intracellular transport pathways.

Fluctuations in brain signals explained: Spontaneous electrical background rhythms in the brain influence fMRI

Until now, brain scans obtained using fMRI – one of the most important imaging methods in use today – have been affected by fluctuations in the brain activity measured which could not be explained. Researchers at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig and the Charité in Berlin have now shown that certain electric background rhythms in the brain, known as Alpha oscillations, alter the fMRI signal obtained with visual stimuli. To do this, they used a new approach in which quickly changing brain activity, which cannot be captured by the scanner, was measured using

Pericardial fat may promote atherosclerosis

Researchers have found more evidence supporting the role of fat around the heart in promoting atherosclerosis, according to a study published online in the journal Radiology.

Study tracks development of chimp brain and makes comparison to humans

In both chimpanzees and humans, portions of the brain that are critical for complex cognitive functions, including decision-making, self-awareness and creativity, are immature at birth. But there are important differences, too. Baby chimpanzees don't show the same dramatic increase in the volume of prefrontal white matter in the brain that human infants do.

Higher protein intake helps postmenopausal obese women lose more weight

Dieting postmenopausal women who want to avoid losing muscle as they lose fat should pay attention to a new University of Illinois study. Adding protein throughout the day not only holds hunger pangs at bay so that dieters lose more weight, it keeps body composition-the amount of fat relative to muscle-in better proportion.

New technique can help scientists rapidly map myelination

Like explorers mapping a new planet, scientists probing the brain need every type of landmark they can get. Each mountain, river or forest helps scientists find their way through the intricacies of the human brain.

Research: 7 Tesla MRI can accurately detect brain scarring linked with epilepsy

Using state-of-the-art, 7 Tesla magnetic resonance imaging (MRI) technology, University of Minnesota Medical School researchers may have uncovered a better approach to diagnosing epilepsy.

New liquid material shows promise for people with facial deformities

Biomedical engineers at Johns Hopkins have developed a new liquid material that in early experiments in rats and humans shows promise in restoring damaged soft tissue relatively safely and durably.

Methods for radiation dose optimization in head CT scans

An article in the August issue of the Journal of the American College of Radiology summarizes methods for radiation dose optimization in head computed tomography (CT) scans. Head CT is the second most commonly performed CT examination, with 28 percent of the total number of CT examinations.

New research shows unique nature of human brain aging

Brains shrink in humans, potentially causing a number of health problems and mental illnesses as people age, but do they shrink to the same extent in the closest living relatives to humans--the chimpanzees? New research says no, making the extreme amount of brain shrinkage resulting from normal aging in humans unique.

Repligen first quarter total revenue increases 9% to $7,654,000

Repligen Corporation today reported results for the first quarter of fiscal year 2012, ended June 30, 2011.

Enrollment begins in Repligen's RG1068 pilot study to improve detection, staging of pancreatic cancer

Repligen Corporation today announced that the first patient has been enrolled in a pilot study to evaluate the ability of RG1068 to improve detection and characterization of pancreatic cancer in combination with contrast-enhanced magnetic resonance imaging (MRI) and computed tomography.

Landmark study may help prevent permanent brain injury in fighters

The Cleveland Clinic Lou Ruvo Center for Brain Health has launched a landmark study with professional fighters that will help determine whether magnetic resonance imaging (MRI) of the brain, along with other tests, can detect subtle changes in brain health that correlate with impaired thinking and functioning.

GE Healthcare's Magnetic Resonance Imaging receives 2011 IDEA awards

GE Healthcare, a unit of General Electric Company, today announced it received several Silver Awards from the 2011 International Design Excellence Awards for Magnetic Resonance Imaging by the Industrial Designers Society of America.

Natural vitamin E may reduce brain damage after stroke

Ten weeks of preventive supplementation with a natural form of vitamin E called tocotrienol in dogs that later had strokes reduced overall brain tissue damage, prevented loss of neural connections and helped sustain blood flow in the animals' brains, a new study shows.

‘City slickers’ at increased brain stress: Study

German and Canadian neuroscientists have shown that living in a city or even being raised in one is associated with differences in the way the brain handles stress. They write in Nature that this is the first time researchers have used functional magnetic resonance imaging (fMRI) to identify specific brain regions that are affected by urban life.

LA/hypnosis combination during surgery can aid healing process, reduce drug use and hospital stay time

Using a combination of hypnosis and local anaesthesia (LA) for certain types of surgery can aid the healing process and reduce drug use and time spent in hospital, anaesthesiologists have found. The combination could also help avoid cancer recurrence and metastases, according to new research to be presented today at the European Anaesthesiology Congress in Amsterdam.
