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.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
