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

Treatment deteriorates giant cell arteritis imaging sensitivity

Patients with suspected giant cell arteritis should undergo imaging before or as soon as possible after treatment has started to minimize the chance of a false–negative result, advise German researchers.

Varying brain activity may reduce risk of Alzheimer's disease

Activity lingers longer in certain areas of the brain in those with Alzheimer's than it does in healthy people, Mayo Clinic researchers who created a map of the brain found. The results suggest varying brain activity may reduce the risk of Alzheimer's disease. The study, "Non-stationarity in the "Resting Brain's" Modular Architecture," was presented at the Alzheimer's Association International Conference and recently published in the journal PLoS One.

New noninvasive imaging technique may help detect heart transplant rejection in children

Cardiologists at Washington University School of Medicine in St. Louis have developed a noninvasive imaging technique that may help determine whether children who have had heart transplants are showing early signs of rejection. The technique could reduce the need for these patients to undergo invasive imaging tests every one to two years.

First-ever captivity-bred bat colony to unlock secrets of behavior, cognition

Mysterious creatures that thrive in the dark, bats have long been associated with witchcraft, vampires, and black magic. But according to Dr. Yossi Yovel of Tel Aviv University's Department of Zoology at Tel Aviv University, we have much to learn from these highly intelligent winged mammals. Now he is developing the world's first bat colony born and raised in captivity to unlock the secrets of behavior and cognition, including social hierarchy and structure, communication abilities, and memory.

Gene defect linked to cluster of systemic complications

Research teams from The University of Texas Health Science Center at Houston (UTHealth) and Paris, France have discovered a gene defect linked to a cluster of systemic complications, including life-threatening thoracic aortic disease and intracranial aneurysms. The new syndrome is similar, but distinct from known syndromes such as Marfan and Loeys-Dietz syndrome.

July issue of Neurosurgery provides update on Human Connectome Project

A research effort called the Human Connectome Project is seeking to explore, define, and map the functional connections of the human brain. An update on progress in and upcoming plans for the Human Connectome Project appears in the July issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Researchers develop first real-time, brain-scanning speller

Researchers have come up with a device that may enable people who are completely unable to speak or move at all to nevertheless manage unscripted back-and-forth conversation. The key to such silent and still communication is the first real-time, brain-scanning speller, according to the report published online on June 28 in Current Biology, a Cell Press publication.

Researchers identify genes that influence degeneration of the hippocampus

In a genome-wide association (GWA) study, researchers from Boston University Schools of Medicine (BUSM) and Public Health (BUSPH) have identified several genes which influence degeneration of the hippocampus, the part of the brain most associated with Alzheimer disease (AD).

Prevalence of significant CAD in patients with chest pain symptoms is lower than expected in Europe

Preliminary findings from the EVINCI study show that the prevalence of "significant" coronary artery disease in patients with chest pain symptoms is lower than expected in Europe. In as much as 75% of this population an accurate non-invasive screening could avoid unnecessary and costly invasive procedures.

High-calorie food images stimulate brain's appetite control center

A picture may be worth a thousand calories, a new study suggests. Looking at images of high-calorie foods stimulates the brain's appetite control center and results in an increased desire for food, according to the study, which will be presented Monday at The Endocrine Society's 94th Annual Meeting in Houston.
