For the first time, researchers have shown that magnetic resonance imaging (MRI) can predict the risk of heart attacks or cardiac deaths in coronary heart disease patients, according to a report in todays rapid access issue of Circulation: Journal of the American Heart Association.
MRI can be used to locate tissue damage in a heart attack or pinpoint blockages, but it has not been used to predict heart attacks.
"This study is the first to determine that MRI is a strong prognostic forecaster," says lead author W. Gregory Hundley, a cardiologist and associate professor of internal medicine and radiology at the Wake Forest University School of Medicine in Winston-Salem, N.C. "Such information is important because it helps us identify which patients should receive more aggressive treatment."

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
