Colorectal cancer is the second leading cause of cancer deaths in the U.S. CTC, a minimally invasive alternative to optical colonoscopy for colorectal cancer screening, employs virtual reality technology to produce a 3-D visualization that permits a thorough evaluation of the entire colon and rectum.
Data on the provision of colorectal cancer screening services by nonfederal, general hospitals were analyzed using the 2005 to 2008 American Hospital Association annual surveys. In addition, in 2009, exploratory interviews were conducted with representatives from radiology departments at nine hospitals; six that provided CTC and three that did not. Researchers found that in 2008, 17 percent of hospitals offered CTC, up from 13 percent in 2005. Sixty-nine percent of hospitals that offered CTC in 2008 also offered optical colonoscopy services. Factors motivating the adoption of CTC included a desire to provide an alternative screening option for frail, elderly patients and patients with failed optical colonoscopy; long waits for optical colonoscopy; and promising evidence on CTC published in peer-reviewed literature. Lack of reimbursement was a commonly cited barrier.
"Our study is unique in that we show expansion even in the absence of Medicare reimbursement for CTC for general screening. CTC's relatively easy implementation coupled with patient acceptance makes CTC a tool that holds promise for the future of colorectal cancer prevention," said Megan McHugh, PhD, lead author of the study.
CTC is proven in clinical trials to be as accurate as standard colonoscopy at detecting clinically significant lesions in average risk patients and is endorsed by the American Cancer Society as a recommended colon cancer screening test. Yet, Medicare does not cover seniors for CTC. As policymakers and others consider ways to increase colorectal cancer screening, it is important to understand US hospitals' readiness to offer CTC and the factors that facilitate or impede adoption.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
