Whole-body computed tomography (CT) is not a cost-effective screening method, according to a study published in the February issue of the journal Radiology.
The use of whole-body CT as a screening tool for cancer and other diseases is the focus of an ongoing debate. Proponents of whole-body CT emphasize the potential benefit of early detection of disease, but others caution that the costs, false-positive findings and unnecessary radiation might render the procedure more harmful than beneficial. "Our findings show that the average person should think twice before having a whole-body CT examination," said study author, G. Scott Gazelle, M.D., Ph.D., director of the Massachusetts General Hospital Institute for Technology Assessment and associate professor of radiology at Harvard Medical School in Boston. "When money is wasted on ineffective interventions, it drives up the cost and decreases the availability of other necessary healthcare interventions," he said.
The researchers evaluated the cost-effectiveness of a single whole-body CT screening examination, which they believe to be the most representative use of whole-body CT. They estimated the cost to be $900 in 2001 dollars, based on advertised prices at the time.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
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....
