By combining different CT views, radiologists can better evaluate the GI tract


Combined evaluation of transverse images--horizontal slices of a standing body--and multiplanar coronal reformats--vertical slices from head to foot--from CT scans give radiologists more information about the GI tract to better diagnose problems, according to a new study by researchers from Emory University School of Medicine in Atlanta, GA.

For the study, the researchers analyzed routine abdomen-pelvis CT studies from 50 patients. The researchers found that with simultaneous review of transverse and coronal images, additional findings were recorded in 10 studies and the doctors had a higher confidence in interpreting 18 of the studies. All together, 281 lesions were detected on simultaneous review of coronal and transverse images, whereas 259 lesions were detected on transverse images alone.

To get these coronal reformats, data from a series of contiguous transverse scan images are recombined, manipulated or processed by the CT technologist at a computer workstation to produce images in the coronal plane.

"If radiologists can detect more findings using both transverse images and coronal reformats as our study suggests, it could definitely benefit patients. In addition, we are generating these coronal reformats from already acquired transverse images, so there is no extra radiation exposure to the patients. These images can be reconstructed from the transverse images at the CT console by the CT technologist in less than a minute," said Sunit Sebastian, MD, lead author of the study.

The full results of the study will be presented on May 4, 2006 during the American Roentgen Ray Society Annual Meeting in Vancouver, BC.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
