Low-dose MDCT of the sinuses in children is effective in diagnosing conditions such as sinusitis and middle ear fluid with a radiation dose comparable to standard x-rays. It also has more benefits, such as better accuracy, speed and a broader diagnosis potential, say researchers from Heilig Hart Hospital in Belgium.
For the study, the researchers compared the imaging results of 69 children who had undergone x-rays and 125 children who had undergone low-dose MDCT. They found that the mean effective radiation dose in x-rays was 0.0528 mSv and that the mean effective radiation dose for MDCT could be brought down to 0.0531 mSv without compromising diagnostic image quality.
According to the researchers, infections of the upper respiratory system are by far the most common cause of illness in infancy and childhood, accounting for approximately 50% of all illness in children younger than five years of age, and 30% in children between the ages of five and 12 years. “About 5 to 13% of these upper respiratory infections are complicated by sinusitis, so it is a common problem with children,” said Tom Mulkens, MD, lead author of the study.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
