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.

Sending tiny electric pulses to a part of the brain controlling motor function boosts stroke recovery

Sending tiny electric pulses to a part of the brain controlling motor function helps ischemic stroke survivors regain partial use of a weakened hand, new Oregon Health & Science University research shows.

Early risk, attention and brain activation in adolescents born preterm

In one of the first studies to use brain imaging with adolescents born prematurely, New Jersey researchers report that the effects of premature birth and environmental risks on the brain during the first three years of childhood continue through adolescence.

Computerized tomography guided percutaneous renal cryoablation with the patient under conscious sedation

When an event occurs once, we have a tendency to look at it as a phenomenon, but when it occurs twice, it begins to enter the realm of accepted reality.

Gene linked to impulsive violence weakens brain circuits that regulate thinking in humans

A version of a gene previously linked to impulsive violence appears to weaken brain circuits that regulate impulses, emotional memory and thinking in humans, researchers at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) have found.

Donepezil (Aricept) helps cognitive function in brain tumor patients after radiation

A drug that is marketed to treat Alzheimer's disease also improves cognitive function, mood and quality of life in brain tumor patients following radiation therapy, according to a research team at Wake Forest University Baptist Medical Center.

Smoking interferes with the brain's ability to recover from the effects of chronic alcohol abuse

"This study suggests that for better brain recovery, it may be beneficial for alcoholics in early abstinence to stop smoking as well," concludes Dieter Meyerhoff, Dr.rer.nat., a radiology researcher at SFVAMC and the senior author of the study. Meyerhoff is also a professor of radiology at the University of California, San Francisco.

Yale School of Medicine expands research using transcranial magnetic stimulation for schizophrenia

Yale School of Medicine researchers are recruiting patients nationally for a clinical trial using transcranial magnetic stimulation (TMS) to help still the voices that are so troubling to some persons with schizophrenia.

Research challenges theories on the organization of the visual system

Neuroscientists from the University of Washington and the University of Minnesota have found that the first area in the cortex of the human brain that receives information from the eyes processes the perceived size, rather than the actual size, of an object.

Dual functions of sight - perception and action - demonstrated for first time

The dissociation in the visual system between two separate functions - one that enables us to identify objects and the other to interact with them - has been clearly demonstrated for the first time in healthy humans by researchers at the Hebrew University of Jerusalem.

Researchers see individual differences in brain activation depending on person's preferences or aversions to risk

Distinct regions of the human brain are activated when people are faced with ambiguous choices versus choices involving only risk, Duke University Medical Center researchers have discovered.

Extensive study of natalizumab

Scientists have completed an extensive study of more than 3,000 patients who received a promising anti-inflammatory drug, natalizumab, that was linked to three cases of a serious brain infection in large clinical trials halted in early 2005.

Treating orthopaedic trauma during pregnancy - most testing and treatments safe for fetuses and mothers

Pregnant women who suffer orthopaedic trauma should be diagnosed and stabilized in the same manner as any other patient, according to research published in the March 2006 issue of the Journal of the American Academy of Orthopaedic Surgeons.

Better tests needed for fuller view of head injuries

Concussion patients with a normal head CT scan may believe they are free of brain injury, but CT scans often miss damage at the molecular level, warns a University of Rochester Medical Center study.

Procedure to remove small tumors near inner ear shows promise at preserving hearing

Even when they're extremely small, tumors on the nerves that connect the brain to the ear can wreak havoc on a person's hearing and balance. But removing them is a delicate process that can, in some cases, cause further harm.

Cutaneous rabbit illusion affects human primary sensory cortex somatotopically

As much as neuroscientists know about the neural processes that signal touch, surprisingly little is understood about the neural correlates of conscious perception of tactile sensations.

Magnetic resonance imaging can help rule out acute appendicitis in pregnancy

Magnetic resonance imaging (MRI) can help rule out acute appendicitis in pregnancy when ultrasound findings are inconclusive, according to a study in the March issue of Radiology.

Engineers identify tiny iron oxide particles associated with Alzheimer's

Engineers have found a way to pinpoint and identify the tiny iron oxide particles associated with Alzheimer's and other neurodegenerative diseases in the brain.

Study associates meniscal damage with advanced cartilage loss in early osteoarthritis

Cartilage loss is a major component of osteoarthritis (OA), a joint disease that affects over 20 million Americans. In knee OA, cartilage loss is influenced by knee injury, as well as obesity and age. Every healthy knee is supported and protected by a pair of meniscus.

Dyslexic children exhibit a different pattern of brain activity while reading

Brain images of children with dyslexia taken before they received spelling instruction show that they have different patterns of neural activity than do good spellers when doing language tasks related to spelling. But after specialized treatment emphasizing the letters in words, they showed similar patterns of brain activity.

Study shows brain anticipates taste

Now, however, scientists have begun to peel back some of the neurological secrets of this remarkable phenomenon and show how the brain can be rewired in anticipation of sensory input to respond in prescribed ways.
