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.

Insulin resistance from obesity leads to lower cognitive performance in children: Research

A study by researchers at NYU Langone Medical Center have found that obese adolescents with type 2 diabetes have diminished cognitive performance and subtle abnormalities in the brain as detected by Magnetic Resonance Imaging (MRI). Identification of cognitive impairments as a complication of type 2 diabetes emphasizes the importance of addressing issues of inactivity and obesity, two important risk factors for the development of the disease among the young.

Particles of iron oxide enhance tumor visibility through MRI

Tiny particles of iron oxide could become tools for simultaneous tumor imaging and treatment, because of their magnetic properties and toxic effects against brain cancer cells. In mice, researchers from Emory University School of Medicine have demonstrated how these particles can deliver antibodies to implanted brain tumors, while enhancing tumor visibility via magnetic resonance imaging (MRI).

Healthy heart may slow down aging of brain: Study

Keep your heart healthy and you may slow down the aging of your brain, according to a new study reported in Circulation: Journal of the American Heart Association.In the study, people whose hearts pumped less blood had brains that appeared older than the brains of those whose hearts pumped more blood. Decreased cardiac index, the amount of blood that pumps from the heart in relation to a person's body size, was associated with decreased brain volume using magnetic resonance imaging (MRI).

Functional MRI can be used to assess tumor viability

Pancreatic ductal adenocarcinoma (the disease commonly referred to as pancreatic cancer) carries the worst prognosis of any cancer. As current treatments offer minimal benefit, entirely new approaches are needed. Given the success of local therapies, as opposed to intravenous systemic therapies, for liver diseases (such as hepatocellular carcinoma), it is thought that similar local therapies may benefit patients with pancreatic cancer. To develop such therapies, it would be useful to devise targets that are easy to obtain and can indicate the efficacy of these new therapies in models of pancreatic cancer.

Resting brain activity associated with spontaneous fibromyalgia pain

A recent study from researchers at Massachusetts General Hospital and University of Michigan provides the first direct evidence of linkage between elevated intrinsic (resting-state) brain connectivity and spontaneous pain intensity in patients with fibromyalgia (FM).

Canada performs fewer diagnostic imaging scans relative to population size than OECD average

Diagnostic tests, such as magnetic resonance imaging (MRI) and computed tomography (CT) scans, are more commonly used on patients in some provinces than in others, according to new data released today by the Canadian Institute for Health Information (CIHI).

Nestle announces collaborative study with Cleveland Clinic Lerner Research Institute on diet rich in whole grains

Nestle USA Chairman and CEO Brad Alford has announced that Nestle Research Center, based in Lausanne, Switzerland, has donated US $500,000 to Cleveland Clinic's Lerner Research Institute. The gift will fund a collaborative study focused on examining the effects of a diet rich in whole grains on body composition and energy metabolism.

GE Healthcare awarded $1M to develop MRI for Pediatrics Populations project

GE Healthcare, a unit of General Electric Company, in collaboration with Cincinnati Children's Medical Center and the Davis Heart and Lung Institute of The Ohio State University, was awarded $1 million for magnetic resonance imaging and devices for the "Pediatrics Population" project. This project reinforces GE's commitment to healthymagination which works to bring new technologies and solutions to more people.

LSDF announces awards for four Washington research teams

The Life Sciences Discovery Fund (LSDF) today announced $600,000 in awards to four Washington state-based research teams to support commercial development of health-related technologies. The funded projects will concentrate on improving the success rate of lumbar punctures (spinal taps) in children; developing a safer and more effective magnetic resonance imaging (MRI) contrast agent; enhancing a DNA sequencing technology to profile T cells within the immune system; and developing a device to detect early stages of tooth decay.

Hip and knee specialist indicates five primary reasons why knee implant fails

While most knee replacements will function well for years, patients should be aware of the signs of failure—including increased pain or decreased function—that may require a corrective procedure known as revision total knee replacement, if necessary.

New methods may help identify early signs of Alzheimer's disease: Study

Abnormal brain images combined with examination of the composition of the fluid that surrounds the spine may offer the earliest signs identifying healthy older adults at risk of developing Alzheimer's disease, well before cognitive problems emerge, a study by researchers at UC Davis has found.

Gore provides update on REDUCE Clinical Study of HELEX Septal Occluder for PFO closure

W. L. Gore & Associates (Gore) today provided an update on the Gore REDUCE Clinical Study, a prospective, randomized, multi-center, multi-national trial designed to demonstrate safety and effectiveness of the GORE HELEX Septal Occluder for Patent Foramen Ovale (PFO) closure in patients with history of cryptogenic stroke or imaging-confirmed Transient Ischemic Attack (TIA). The unique study, which includes up to fifty investigational sites in the U.S., Denmark, Finland, Norway and Sweden, is on track to meet its estimated completion in 2015.

Early knowledge of HCC response to TACE determines treatment success: Research article

Early knowledge of hepatocellular carcinoma response to transcatheter arterial chemoembolization is crucial for determining treatment success, timing of repeat treatment, and patient prognosis. Currently, magnetic resonance imaging is used 1-3 mo after treatment to evaluate anatomical tumor response, based upon changes in tumor size and contrast-agent enhancement. Alternatively, diffusion-weighted imaging can be used as a functional imaging technique to depict thermally induced motion of water molecules.

Report: Health spending outpaces economic growth in wealthy countries

Reuters on a report from the Organisation for Economic Cooperation and Development: The increase in health spending is "piling pressure budgets already hit" by the recession and is "likely to continue rising as populations age, technology improves and public expectations grow. ... Given the urgent need to reduce their budget deficits, many OECD governments will have to make difficult choices to sustain their healthcare systems: curb the growth of public spending on health, cut spending in other areas, or raise taxes," according to the report.
