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.

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.

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.

Research shows promise for stopping progression of bipolar disorder

Changes in the brain that are important indicators of bipolar disorder are not prominent until young adulthood and are reduced in persons taking mood-stabilizing medications, Yale School of Medicine researchers report this month in Biological Psychiatry.

Women more sensitive to pain during periods of low estrogen

Now researchers are going one step further by studying whether the difference in pain sensitivity is reflected in brain activity as measured by functional magnetic resonance imaging (fMRI).

Imaging technology detects subtle brain changes in Type 1 diabetics

Although people with diabetes are twice as likely as the general population to develop depression, the cause of this increased risk is not well understood.

Study finds brain changes begin gradually in 'middle age'

A study looking at brain function in young, middle-aged and older adults has identified changes in brain activity that begin gradually in middle age - and which may explain why older adults find it difficult to concentrate in busy environments and filter out irrelevant information.

Women with low estrogen levels more sensitive to pain

Several recent studies have found that women are more sensitive to pain during periods of low estrogen.

New treatment trials for autosomal dominant polycystic kidney disease

The National Institutes of Health (NIH) and the PKD Foundation have launched two treatment trials for autosomal dominant polycystic kidney disease (ADPKD).

Discovery puts scientists closer to understanding how visual awareness is generated

How do you know when you see something? Researchers at Barrow Neurological Institute in Phoenix have made a breakthrough discovery that puts scientists closer to understanding how visual awareness is generated.

Face perception is mediated by a distributed neural system in the human brain

New research indicates that an area of the brain thought to act in reward circuitry may represent a phase in visual processing during which sexual orientation modulates how we perceive individual faces. The findings are reported by Felicitas Kranz and Alumit Ishai of the University of Zurich.

Study establishes two forms of mild cognitive impairment

Mild cognitive impairment (MCI), a transitional stage between normal cognition and Alzheimer's disease, exists in two different forms, according to a study published today by researchers from the University of Pittsburgh School of Medicine and the University of California, Los Angeles in the Archives of Neurology.

Myelin breakdown appears to be key contributor to Alzheimer disease later in life

A new UCLA imaging study shows that age-related breakdown of myelin, the fatty insulation coating the brain's internal wiring, correlates strongly with the presence of a key genetic risk factor for Alzheimer disease.
