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.

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.

Exercise re-ignites key areas of the brain

Too old to learn new skills? By golly, think again. New research at the University of Illinois at Urbana-Champaign shows that training re-ignites key areas of the brain, offsetting some age-related declines and boosting performance.

Functional magnetic resonance imaging better than polygraph to find liars

Traditional polygraph tests to determine whether someone is lying may take a back seat to functional magnetic resonance imaging (fMRI), according to a study appearing in the February issue of Radiology.

Mangafodipir appears to increase the cancer-killing ability of some chemotherapy drugs

A contrast agent currently used in magnetic resonance imaging (MRI), called mangafodipir, may increase the cancer-killing ability of some chemotherapy drugs while protecting normal cells, according to a study in the Journal of the National Cancer Institute.

21 Feb 2006

Researchers show that linguistic rules are processed in two phylogenetically different brain regions

Researchers found that simple language structures are processed in an area that is phylogenetically older, and which apes also possess. Complicated structures, by contrast, activate processes in a comparatively younger area which only exists in a more highly evolved species: humans.

Botox finds a use in cancer treatment

The cosmetic treatment Botox may have a new use as an adjuvant to cancer therapy, providing an open door for chemotherapy and radiation treatments, according to a study published in the Feb. 15 issue of Clinical Cancer Research.

Researchers develop way to visualize synchronized interactions of nerve cells in the brain

Researchers at the University of Minnesota Medical School and the Brain Sciences Center at the Minneapolis VA Medical Center have discovered a new way to assess how brain networks act together.

Brain scans may detect neurological decline in normal people

Brain scans may detect neurological changes in people who exhibit no outward signs of cognitive decline but who later develop dementia or mental impairment, according to the results of a new study led by researchers at the University of California, Berkeley.

MRI can detect breast disease missed by mammography

Researchers have found that mammography coupled with magnetic resonance imaging (MRI) is extremely sensitive in the detection of ductal carcinoma in situ (DCIS). DCIS, or early stage breast carcinoma, is a pre-invasive malignancy and MRI may help identify this type of disease, which may not be visible on a mammogram.

UT Southwestern embraces robotic technology to advance future of surgery

Having a surgeon with four arms is one of the advantages of the latest robotic technology now being studied at UT Southwestern Medical Center.
