Magnetic resonance imaging (MRI) is an imaging technique which physicians use for the diagnosis and treatment of medical conditions.

Magnetic iron oxide nanoparticle-induced hyperthermia can kill cancer cells

Using nanoparticles and alternating magnetic fields, University of Georgia scientists have found that head and neck cancerous tumor cells in mice can be killed in half an hour without harming healthy cells.

Obese youths with particular genetic variants may be more prone to fatty liver disease

Obese youths with particular genetic variants may be more prone to fatty liver disease, a leading cause of chronic liver disease in children and adolescents in industrialized countries, according to new findings by Yale School of Medicine researchers.

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.

Bolus intracoronary abciximab reduces infarct size in high-risk patients with STEMI

Administration of a bolus dose of the anticoagulant drug abciximab into the coronary artery involved in causing a certain type of heart attack among patients who were undergoing a percutaneous coronary intervention and also receiving another anticoagulant resulted in reduction in the size of damage to the heart muscle at 30 days, while a procedure that involved use of a catheter to remove the blood clot blocking that coronary artery did not produce these results, according to a study appearing in JAMA.

New embolization procedure may bring hope to men with enlarged prostate

A new interventional radiology treatment, prostatic artery embolization, may bring hope to men with debilitating symptoms caused by an enlarged prostate, say the group of researchers who pioneered its use.

New IVIG trial can reduce OCD symptoms in children with PANDAS

Criteria for a broadened syndrome of acute onset obsessive compulsive disorder (OCD) have been proposed by a National Institutes of Health scientist and her colleagues. The syndrome, Pediatric Acute-onset Neuropsychiatric Syndrome (PANS), includes children and teens that suddenly develop on-again/off-again OCD symptoms or abnormal eating behaviors, along with other psychiatric symptoms - without any known cause.

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.

WCI technique uses MRS to detect oncometabolites

Researchers at Winship Cancer Institute have developed a technique for detecting an "oncometabolite", a chemical produced by some brain tumors' warped metabolism, via non-invasive imaging.

Study shows how brain function differs in children with math anxiety

Scientists at the Stanford University School of Medicine have shown for the first time how brain function differs in people who have math anxiety from those who don't.

Computer program could help dementia patients manage their disease

Researchers at Weill Cornell Medical College have developed a computer program that has tracked the manner in which different forms of dementia spread within a human brain. They say their mathematic model can be used to predict where and approximately when an individual patient's brain will suffer from the spread, neuron to neuron, of "prion-like" toxic proteins -- a process they say underlies all forms of dementia.

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.

Alzheimer's may spread through connected neurons

Alzheimer's disease and other forms of dementia may spread within nerve networks in the brain by moving directly between connected neurons, instead of in other ways proposed by scientists, such as by propagating in all directions, according to researchers who report the finding in the March 22 edition of the journal Neuron.

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.

Infants' faces evoke species-specific patterns of brain activity in adults

Distinct patterns of activity-which may indicate a predisposition to care for infants-- appear in the brains of adults who view an image of an infant face-even when the child is not theirs, according to a study by researchers at the National Institutes of Health and in Germany, Italy, and Japan.

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.

Higher spending on effective procedures and services leads to better patient outcomes

Among hospitals in Ontario, Canada, those with higher levels of spending, which included higher intensity nursing and greater use of specialists and procedures, had an associated lower rate of deaths, hospital readmissions, and better quality of care for severely ill hospitalized patients, according to a study in the March 14 issue of JAMA.
