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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
