The study, performed at Lucile Packard Children's Hospital, Stanford School of Medicine, in Stanford, CA, included 120 children who underwent chest CT scans — 60 children weighed less than 15 kg (33 pounds) and 60 weighed between 15 and 16 kg (33 – 132 pounds). Radiologists adjusted their chest CT protocols by lowering the radiation dose according to patient weight.
"For children weighing less than 33 pounds, we were able to reduce the radiation dose by approximately 73 percent," said Beverley Newman, MD, lead author of the study. "For children weighing between 33 and 132 pounds, we were able to reduce the radiation dose by approximately 48 percent," said Newman.
"CT examinations are commonly performed in the pediatric population. However radiation dose related to CT has become a public health concern, and appropriate reduction of radiation dose has become an important goal in pediatric CT," she said.
"While it is important to keep radiation doses as low as possible, it is important not to compromise the diagnostic usefulness of the scan. In our study, lowering the radiation dose did increase image noise resulting in grainy images. However the low dose examinations were still considered diagnostically acceptable," said Newman.
"As our study suggests, significant dose reduction can be achieved for routine pediatric chest CT by paying attention to simple protocol adjustments based upon patient weight," she said.

The American Roentgen Ray Society (ARRS) was founded in 1900 and is the oldest radiology society in the United States. Its monthly journal, the American Journal of Roentgenology, began publication in 1906. Radiologists from all over the world attend the ARRS annual meeting to participate in instructional courses, scientific paper presentations and scientific and commercial exhibits related to the field of radiology. The Society is named after the first Nobel Laureate in Physics, Wilhelm Röentgen, who discovered the x-ray in 1895.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
