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

Obese individuals with excess visceral fat more likely to develop type 2 diabetes

Obese individuals with excess visceral fat (abdominal fat that surrounds the body-s internal organs) have an increased risk for the development of Type 2 diabetes, according to a new study by researchers at UT Southwestern Medical Center. By contrast, persons with excess abdominal subcutaneous fat (fat underneath the skin) were not at higher risk for the onset of diabetes.

Teen BD patients show specific gray matter deficits

Results from a US study show that adolescents with bipolar I disorder who have experienced their first episode of mania have gray matter deficits in the left subgenual cingulate cortex.

Ionizing radiation imaging raises breast cancer risk in BRCA1/2 carriers

Exposure to ionizing radiation at an early age increases the risk for breast cancer among women with BRCA1/2 mutations, reveals research published in the BMJ.

‘C’ variant disrupts brain connectivity in children with ASD

Over the past decade, researchers have made great strides in identifying genes that lead to an increased risk of autism spectrum disorders (ASD), which result in a continuum of social deficits, communication difficulties and cognitive delays. But it's still critical to determine how exactly these genetic risk factors impact the brain's structure and function so that better treatments and interventions can be developed.

Childhood abuse linked to thalamus size in violent mental health patients

Childhood psychosocial deprivation is associated with significantly reduced thalamic volume among violent individuals with antisocial personality disorder or schizophrenia, researchers report.

Moderate exercise may help people cope with future anxiety and stress

Moderate exercise may help people cope with anxiety and stress for an extended period of time post-workout, according to a study by kinesiology researchers in the University of Maryland School of Public Health published in the journal Medicine and Science in Sports and Exercise.

Silent infarcts prognostic in young stroke patients

Silent ischemic lesions are common and are associated with a high rate of recurrent events in young patients with acute ischemic stroke, report researchers.

Specific white matter connectivity reduced in anxiety patients

Patients with generalized anxiety disorder have reduced functional connectivity between areas of the brain associated with fight-or-flight response and emotion regulation, researchers report.

MRI workers experience transient neurocognitive effects

Individuals working in the vicinity of magnetic resonance imaging machines may experience transient neurocognitive effects when moving their heads, research demonstrates.

Teenage brains being changed by the digital revolution

The digital revolution appears to be changing the adolescent brain to enable it to cope with constant technological stimulation, says visiting U.S. adolescent brain researcher Dr Jay Giedd.

Delayed WM growth in siblings of childhood-onset schizophrenia patients

The unaffected adolescent siblings of patients with childhood-onset schizophrenia show reduced white matter growth rates compared with other adolescents, researchers report.

Posterior medial cortex more specifically engaged in recall or imagination

You already know it's hard to balance your checkbook while simultaneously reflecting on your past. Now, investigators at the Stanford University School of Medicine - having done the equivalent of wire-tapping a hard-to-reach region of the brain - can tell us how this impasse arises.

MRI lesions match site of recent-onset inflammatory back pain

Patients with recent inflammatory back pain who undergo examination with magnetic resonance imaging typically show inflammation at the site of their pain, a study confirms.

MRI detects high prevalence of abnormalities associated with knee osteoarthritis

A study conducted by researchers at Boston University School of Medicine (BUSM) shows that magnetic resonance imaging (MRI) detected a high prevalence of abnormalities associated with knee osteoarthritis in middle-aged and elderly patients that had no evidence of knee osteoarthritis in X-ray images.

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.
