The study consisted of 932 patients who underwent plain radiographs and abdomen and pelvis CT within three days of an injury. These patients were divided into groups of: with lumbar spine fracture and without lumbar spine fracture.
According to the study, 180 (19.3%) of the patients had a fracture of the lumbar spine, diagnosed by either modality. Of the 180 patients, CT was positive for fracture in 165 (91.7%) while the plain films were positive for 101 out of 180 patients (56.4%).
The study found that 8.3% of the fractures were missed by CT while 43.9% were missed by plain film. Of that 8.3% (15) that were missed by CT, 11 represented compression deformities of indeterminate age, three were possible transverse process fractures and one was a superior end plate fracture.
"The results of our study determined that lumbar spine radiographs did not provide additional information in trauma patients who underwent abdomen and pelvis CT with lateral scout," said Sangita Kapur, MD, lead author of the study. "If our results are applied to clinical practice and lumbar spine plain films are not routinely obtained, it will help save critical time for these patients and also save valuable resources. Unnecessary radiation exposure can also be avoided," she said.
The full results of this study will be presented on Monday, May 7, 2007 during the American Roentgen Ray Society’s annual meeting in Orlando, FL.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
