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.

Diabetes and heart disease may stem from fat you can't see

Becoming fat brings conspicuous changes to the shape of the human body, but pioneering research in the Department of Medicine at Flinders University, Australia is working on the theory that the obvious "spare tyre" may not be the major culprit in fat-related diseases.

Limb-sparing technique called rotationplasty helps very young children with bone cancer

The current issue of New England Journal of Medicine illustrates a case of a five-year-old girl with Ewing’s sarcoma, a cancerous tumor, behind her left knee. Surgeons at The Children’s Hospital of Philadelphia used a limb-sparing technique called rotationplasty to remove the diseased portion of bone, turn the shortened portion of the leg bone in a half-circle and reattach it, with the ankle joint functioning as a knee.

Organ transplant recipients infected with West Nile virus develop more severe neurological illness

West Nile virus is an infection which in the last three years has had a significant impact in the United States. The virus is spread from birds to humans via mosquito bites. Symptoms include headache, fever and disorientation, and the disease can cause serious illness in a small percentage of infected people.

Immunotherapy and chemotherapy combined, slows tumor progression and extends survival of patients with glioblastoma multiforme

Researchers at Cedars-Sinai's Maxine Dunitz Neurosurgical Institute have found that the combination of immunotherapy and chemotherapy significantly slowed tumor progression and extended survival of patients with glioblastoma multiforme (GBM).

Scientists have tricked subjects in an experiment into believing that a rubber hand was part of their own body

The findings about the brain’s awareness of its own body will hopefully lead to better understanding of disorders of self-perception, as for example in brain-damaged patients who no longer recognise their own limbs after stroke, or amputees who still experience pain from limbs that are no longer there.

MRI may be better than polygraph for revealing lies

A new study involving people telling lies while undergoing functional magnetic resonance imaging (fMRI) provides early indications that understanding the brain basis of deception may lead to a better lie detection method than polygraph tests.

Physicians offer several promising and unique approaches to brain tumor treatment

An estimated 41,000 new cases of primary brain tumors are expected to be diagnosed in 2004, according to the American Brain Tumor Association.

Smart drug that targets cancer cells in the brain following removal of a tumor

The use of a "smart" drug that targets cancer cells in the brain following removal of a tumor may provide treatment that can extend the survival of people with the most common form of primary malignant brain tumor, glioblastoma multiforme (GBM).

Pacemakers and defibrillators can be safe for use in magnetic resonance imaging machines

In animal and laboratory studies, scientists at Johns Hopkins have shown that modern, implanted heart assist devices - such as pacemakers and defibrillators - can be safe for use in magnetic resonance imaging (MRI) machines

Computer-aided detection (CAD) can help physicians locate and analyze images from computed tomography (CT) scans

The diagnostic imaging modality of computed tomography (CT) scan is very helpful in lung cancer assessment as it spots even small lung tumors that might go undetected in conventional chest X-ray and other tests.

Cardiologist studying new method of screening for heart disease

A multi-center study led by Wake Forest University Baptist Medical Center cardiologist David M. Herrington, M.D., M.H.S., suggests that measuring the stiffness of arteries to screen for early atherosclerosis may be another way to identify people at risk for heart disease or stroke.

Several key findings from clinical trial of an investigational Alzheimer's disease treatment

Elan Corporation and Wyeth Pharmaceuticals have announced several key findings from their Phase IIa clinical trial of an investigational Alzheimer's disease (AD) treatment, AN-1792, which were presented in Philadelphia at the 9th International Conference on Alzheimer's Disease and Related Disorders.

People who have early stage Alzheimer's disease could be more capable of learning than previously thought

The promising studies suggest that some people with early cognitive impairment can still be taught to recall important information and to better perform daily tasks.

Rabies infections in organ donor and transplant recipients

On June 30, 2004, CDC confirmed diagnoses of rabies in three recipients of transplanted organs and in their common donor, who was found subsequently to have serologic evidence of rabies infection.

Brain recordings may shed light on disorders of self-perception such as schizophrenia, stroke and phantom limb syndrome

Scientists have made the first recordings of the human brain’s awareness of its own body, using the illusion of a strategically-placed rubber hand to trick the brain.

Positron emission tomography offers a better way to observe the damage that strokes and neurodegenerative diseases wreak on brain cells

A laser-based microscopy technique may have settled a long-standing debate among neuroscientists about how brain cells process energy

Vascular dementia, a common form of dementia often mistaken for Alzheimer’s disease

Alzheimer’s isn’t always the cause of a progressive loss of memory and other mental skills.

Sex hormones alter the development of certain brain structures during puberty

The results, in press with NeuroImage, show that sex hormones alter the development of certain brain structures during puberty and that these effects persist into adulthood.

Experimental therapy improves arm function in chronically impaired stroke survivors

An experimental therapy improves arm function in chronically impaired stroke survivors long after the possibility of spontaneous recovery has been exhausted, researchers reported today at the 5th World Stroke Congress.

Virtual reality appears to dramatically change how the brain physically registers pain

The work, which used a specialized type of magnetic resonance imaging to track pain-related brain activity, showed drops of as much as 97 percent in such activity in some brain centers. The study marks the first time that scientists have documented a link between virtual reality and pain reduction in terms of an actual physiological response.
