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

Low incentive fails to 'switch off' brain regions involved in mind-wandering among ADHD children

Brain scans of children with attention-deficit/hyperactivity disorder (ADHD) have shown for the first time why people affected by the condition sometimes have difficulty in concentrating. The study, by experts at The University of Nottingham, may explain why parents often say that their child can maintain concentration when they are doing something that interests them, but struggles with boring tasks.

P. gingivalis infection accelerates inflammation and atherosclerosis in the innominate artery

Atherosclerosis is the leading cause of death in the developed world. While a number of risk factors for atherosclerosis have been defined, scientists continue to study other possible risk factors for this disease. Recent epidemiological and experimental studies link infectious agents with the development of inflammatory atherosclerosis. A hallmark of chronic infection with the oral pathogen Porphyromonas gingivalis is the induction of a chronic inflammatory response.

Clinical Decision Support Systems help reduce unnecessary CT and MRI scans

Researchers from Virginia Mason Medical Center in Seattle, WA, have found that clinical decision support systems can help reduce inappropriate medical imaging, including unnecessary computed tomography (CT) and magnetic resonance imaging (MRI) scans, according to a study in the January issue of the Journal of the American College of Radiology (www.jacr.org).

Non-radiologist physicians are paid more for NDI by Medicare than radiologists

Researchers have found that Medicare payments for non-invasive medical imaging, including magnetic resonance imaging and computed tomography scans, are now higher to non-radiologists than to radiologists, according to a study in the January issue of the Journal of the American College of Radiology.

Bupropion and varenicline help curb cigarette craving

The smoking cessation medications bupropion and varenicline may both be associated with changes in the way the brain reacts to smoking cues, making it easier for patients to resist cravings, according to two reports posted online today that will appear in the May print issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Reviewing medical imaging on portable media presents a problematic venture

Radiologists and referring clinicians frequently use portable media to review patient medical images acquired at outside imaging centers, including magnetic resonance imaging and computed tomography scans, but issues regarding access, importability, and viewing of these portable media exist, according to a study in the January issue of the Journal of the American College of Radiology.

Amygdala may contribute to rich, varied social life among humans: Scientists

Scientists have discovered that the amygdala, a small almond shaped structure deep within the temporal lobe, is important to a rich and varied social life among humans. The finding was published this week in a new study in Nature Neuroscience and is similar to previous findings in other primate species, which compared the size and complexity of social groups across those species.

Brain regions that 'fire up' due to suppression of automatic behaviour

Research from York University is revealing which regions in the brain "fire up" when we suppress an automatic behaviour such as the urge to look at other people as we enter an elevator.

New study shows how meditators don't ponder pain

Zen meditation has many health benefits, including a reduced sensitivity to pain. According to new research from the Universit- de Montr-al, meditators do feel pain but they simply don't dwell on it as much. These findings, published in the month's issue of Pain, may have implications for chronic pain sufferers, such as those with arthritis, back pain or cancer.
