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.

SBU to advance research and clinical care at National Pediatric MS Center

Stony Brook University has received a $2.5 million gift from Robert and Lisa Lourie to advance research and clinical care at the National Pediatric Multiple Sclerosis (MS) Center at Stony Brook Long Island Children's Hospital and to establish a new state-of-the-art imaging center at Stony Brook Medicine.

Computer modeling supports theory that many dementias spread like prion diseases

A new technique for analyzing brain images offers the possibility of using magnetic resonance imaging (MRI) to predict the rate of progression and physical path of many degenerative brain diseases, report scientists at the San Francisco VA Medical Center and the University of California, San Francisco.

Neugrid opens new channels of research into degenerative neurological disorders

Through the Neugrid project, the pan-European grid computing infrastructure has opened up new channels of research into degenerative neurological disorders and other illnesses, while also holding the promise of quicker and more accurate clinical diagnoses of individual patients.

Ultrasound & MRI as additions to mammograms for breast cancer detection

A new study shows that annual mammogram screenings, combined with ultrasounds and MRIs, significantly increase the detection of cancer in women who had an elevated risk of breast cancer.

Addition of ultrasound and MRI to annual mammography effectively detects incident breast cancers

The addition of a screening ultrasound or magnetic resonance imaging (MRI) to annual mammography in women with an increased risk of breast cancer and dense breast tissue resulted in a higher rate of detection of incident breast cancers, according to a study in the April 4 issue of JAMA.

Nine physician organizations identify specific tests or procedures that may be unnecessary

Nine leading physician specialty societies have identified specific tests or procedures that they say are commonly used but not always necessary in their respective fields. Patient advocates are calling the move a significant step toward improving the quality and safety of health care.

Childhood onset temporal lobe epilepsy has a significant impact on brain aging

New research confirms that childhood onset temporal lobe epilepsy has a significant impact on brain aging. Study findings published in Epilepsia, a peer-reviewed journal of the International League Against Epilepsy (ILAE), show age-accelerated ventricular expansion outside the normal range in this patient population.

Brain images show nerves ‘crisscrossing’ in neat but complex patterns: Study

New images of the brain reveal a deceptively simple pattern of organization in the wiring of this complex organ. Instead of nerve fibers travelling randomly through the brain like spaghetti, as some imaging has suggested, the new portraits reveal two-dimensional sheets of parallel fibers ‘crisscrossing’ other sheets at right angles in a grid-like structure that folds and contorts with the convolutions of the brain. This same pattern appeared in the brains of humans, rhesus monkeys, owl monkeys, marmosets and galagos, researchers report Thursday in the journal Science.

Scientists produce first genetic brain atlas

The first atlas of the surface of the human brain based upon genetic information has been produced by a national team of scientists, led by researchers at the University of California, San Diego School of Medicine and the VA San Diego Healthcare System.

New technique can detect small secondary brain tumours

Cancer Research UK scientists have developed a technique they believe could be used to detect tiny secondary tumours in the brain, a process that is currently impossible, according to research published in PNAS.

FDA Advisory Committee to review Repligen's SecreFlo NDA on May 31

Repligen Corporation today announced that the U.S. Food and Drug Administration's Gastrointestinal Drugs Advisory Committee will meet on May 31, 2012 to discuss the Company's New Drug Application (NDA) for SecreFlo for the improved detection of pancreatic duct abnormalities in combination with magnetic resonance imaging (MRI) in patients with pancreatitis.

Obese children with PNPLA3 and GCKR genetic variants more susceptible to fatty liver disease

New research found the genetic variant Patatin-like phospholipase domain containing protein-3 (PNPLA3) acting in conjunction with the glucokinase regulatory protein (GCKR) is associated with increased susceptibility to fatty liver disease in obese children.

MRI screening could be cost effective for women with familial risk of breast cancer

Adding magnetic resonance imaging (MRI) to standard breast cancer screening approaches is expensive, though it could be cost effective for a group of women who may not have inherited the breast cancer susceptibility genes, but who have a familial risk of developing the disease.

Tomosynthesis may be more beneficial in diagnosing knee OA than X-ray imaging

A recent study done by researchers at Boston University School of Medicine (BUSM) shows that tomosynthesis may be more beneficial in diagnosing knee osteoarthritis than X-ray imaging.

Scans reveal Williams syndrome-associated personality/temperament traits

A personality profile marked by overly gregarious yet anxious behavior is rooted in abnormal development of a circuit hub buried deep in the front center of the brain, say scientists at the National Institutes of Health. They used three different types of brain imaging to pinpoint the suspect brain area in people with Williams syndrome, a rare genetic disorder characterized by these behaviors.

Addition of two MRI sequences to MRPA improves detection of pulmonary embolism

New research shows that the addition of two magnetic resonance imaging (MRI) sequences to a common MR angiography technique significantly improves detection of pulmonary embolism, a potentially life-threatening condition traditionally diagnosed through computed tomography.

NEJM publishes results from Teva's laquinimod Phase III study on RRMS

Teva Pharmaceutical Industries Ltd. and Active Biotech today announced the publication of results from the laquinimod Phase III ALLEGRO study in the March 15 issue of The New England Journal of Medicine.

Scientists use novel system to discover sequential firing of neurons

Princeton University researchers have used a novel virtual reality and brain imaging system to detect a form of neural activity underlying how the brain forms short-term memories that are used in making decisions.

MRI perfusion imaging can help determine brain tumor progression

Gliomas, the most common malignant brain tumors in adults, can be difficult to treat because of their aggressive and invasive nature. In treating patients with gliomas, it is increasingly important that doctors be able to detect tumor changes early when there's a better chance for recovery.
