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

Study may spur research into multi-model imaging based biomarker development for AD

Alzheimer's disease (AD) is one of the most common brain disorders, with an estimated 35 million people affected worldwide. In the last decade, research has advanced our understanding of how AD affects the brain. However, diagnosis continues to rely primarily on neuropsychological tests which can only detect the disease after clinical symptoms begin. In a supplement to the Journal of Alzheimer's Disease, investigators report on the development of imaging-based biomarkers that will have an impact on diagnosis before the disease process is set in motion.

Strong neural communication between the hemispheres predicts math performance

A new study by researchers at UT Dallas' Center for Vital Longevity, Duke University, and the University of Michigan has found that the strength of communication between the left and right hemispheres of the brain predicts performance on basic arithmetic problems. The findings shed light on the neural basis of human math abilities and suggest a possible route to aiding those who suffer from dyscalculia-- an inability to understand and manipulate numbers.

Bleeding risk from aneurysm high in hemorrhagic AVM radiosurgery

In patients undergoing stereotactic radiosurgery for hemorrhagic arteriovenous malformations, endovascular or surgical strategies that reduce bleeding risk should be used if an aneurysm is found, advise US researchers.

Alcohol can cause more than one pattern of birth defects

A collaborative research effort by scientists at the University of North Carolina School of Medicine, Duke University, and University College of London in the UK, sheds new light on alcohol-related birth defects.

Study demonstrates MRI role in defining and understanding causes of MS

New magnetic resonance imaging (MRI) research shows that changes in brain blood flow associated with vein abnormalities are not specific for multiple sclerosis (MS) and do not contribute to its severity, despite what some researchers have speculated. Results of the research are published online in the journal Radiology.

No return of body fat following liposuction

Body fat does not return in the treated or untreated areas of patients undergoing liposuction and/or abdominoplasty, research shows.

Pulvinar regulates communication between clusters of brain cells

A mysterious region deep in the human brain could be where we sort through the onslaught of stimuli from the outside world and focus on the information most important to our behavior and survival, Princeton University researchers have found.

Ion levels poor indicator for hip arthroplasty debris

Research shows that plasma metal ion analysis is only moderately effective at identifying patients with adverse reaction to metal debris following metal-on-metal hip arthroplasty.

Early MRI scans for acute lower back injury may lead to increased disability

If you've recently hurt your back on the job, getting a magnetic resonance imaging (MRI) scan won't increase your chances of a good recovery, suggests a study in the August 15 issue of Spine. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Researchers develop multi-dimensional MRI method to assess age in children

A national team of researchers led by investigators at the University of California, San Diego School of Medicine have developed a multidimensional set of brain measurements that, when taken together, can accurately assess a child's age with 92 percent accuracy.

Sophisticated brain scans can accurately predict age

It isn't uncommon for people to pass for ages much older or younger than their years, but researchers have now found that this feature doesn't apply to our brains. The findings reported online on August 16 in Current Biology, a Cell Press publication, show that sophisticated brain scans can be used to accurately predict age, give or take a year.

Febrile seizures increase hippocampal injury risk

Children with febrile status epilepticus are at risk for hippocampal injury and show abnormalities in the development of this brain area, show findings from a prospective multicenter study.

Short-term intervention alters neural architecture of stutterers

A short-term intervention in patients who stutter can help reorganize the intrinsic functional architecture of speech–language processes, a Chinese study shows.

Brain language structures altered in patients at genetic risk for schizophrenia

Mentally healthy individuals with a family history of schizophrenia display alterations in brain areas associated with language, US researchers report.

High-cost imaging increasingly used for stage IV cancer patients

High-cost diagnostic imaging was increasingly used for elderly patients with stage IV cancer of the breast, lung, and prostate, and colorectal cancer in the USA, research demonstrates.

New 3-D view of the body's response to infection

A new 3-D view of the body's response to infection - and the ability to identify proteins involved in the response - could point to novel biomarkers and therapeutic agents for infectious diseases.

Leukoaraiosis modifies brain function in the elderly

Researchers at the Mayo Clinic say a common condition called leukoaraiosis, made up of tiny areas in the brain that have been deprived of oxygen and appear as bright white dots on MRI scans, is not a harmless part of the aging process, but rather a disease that alters brain function in the elderly.

Effects on white matter brain volume from long-term alcoholism are different for men and women

(Boston) - Researchers from Boston University School of Medicine (BUSM) and Veterans Affairs (VA) Boston Healthcare System have demonstrated that the effects on white matter brain volume from long-term alcohol abuse are different for men and women. The study, which is published online in Alcoholism: Clinical and Experimental Research, also suggests that with abstinence, women recover their white matter brain volume more quickly than men.

Frontal-amygdala connectivity alterations in BDI patients

Results from a US study suggest there is dysfunction in the neural networks responsible for emotion regulation among patients with bipolar I disorder, even during periods of euthymia.

Novel model may allow clinicians to predict potential for recovery after SCI

For more than 1 million people in the U.S. living with spinal cord injury, the frightening days and weeks following the injury are filled with uncertainty about their potential for recovery and future independence. A new model based on motor scores at admission and early imaging studies may allow clinicians to predict functional outcomes and guide decision-making for therapy and care-giving needs, as described in an article published in Journal of Neurotrauma, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
