“We found that the use of ultrasound to diagnose patients greatly reduced radiation exposure for patients without negatively affecting their health,” said Margarita Oks, MD, Long Island Jewish Hospital, North Shore-LIJ Health System. “It was also cost-effective.”
Ultrasound, also called sonography, is an imaging method that uses high-frequency sound waves to produce images that lead to diagnosis and treatment of many diseases and medical conditions. Radiation is not used in ultrasound testing, but is used in x-rays and CT scans.
Dr. Oks and her colleagues studied medical charts covering 3 months of data comparing chest x-rays, CT scans, and ultrasound between two independent but similar medical intensive care units staffed by the same medical house staff in one health-care system. One unit used bedside ultrasound as the standard of care for diagnosis; the second used conventional imaging, such as x-rays and CT scans, as its standard of care in diagnosis.
Researchers found that there were 5.21 x-rays done per patient stay in the ICU using x-rays and CT scans, while there were 1.10 x-rays per patient stay in the unit using ultrasound as the standard of care. Total CT scans were 0.91 in the nonultrasound ICU vs 0.26 per patient stay in the ultrasound unit. There were 0.27 cardiac echocardiograms in the nonultrasound ICU vs 0.11 in the ultrasound ICU per patient stay. Mortality rates did not differ greatly, with 0.27 in the nonultrasound ICU vs 0.20 in the ultrasound ICU.
CHEST 2013 is the 79th annual meeting of the American College of Chest Physicians, held October 26-31 in Chicago, Illinois. The ACCP is the global leader in clinical chest medicine, representing 18,700 members who provide patient care in the areas of pulmonary, critical care, and sleep medicine in the United States and throughout the world. The mission of the ACCP is to promote the prevention, diagnosis, and treatment of chest diseases through education, communication, and research. For information about the ACCP, visit the ACCP website at www.chestnet.org, or follow the ACCP on Facebook and Twitter and the meeting hashtag, #CHEST2013.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
