“Full-field digital tomosynthesis is mammography--only better,” researchers say of a new technique that just might be the next generation of breast cancer screening. Two new studies on this technique illustrate that full-field digital tomosynthesis (TOMO) can not only increase the visibility of breast lesions but could likely dramatically reduce the number of patients being called back for a second mammogram because their first screening mammogram was unclear.
In the first study, researchers compared standard plain film mammography to TOMO. Forty patients were included in the study. Radiologists detected 16 of 22 malignant lesions on mammography and 18 of 22 malignant lesions on TOMO, says Elizabeth Rafferty, MD, lead author of both studies. TOMO was superior to plain film mammography in detecting masses and architectural distortions, which results from a tethering or pulling in of the tissue, says Dr. Rafferty. Calcifications were not as conspicuous on the tomosynthesis imaging during the pilot study, she says. “We are currently implementing a solution to this challenge and will have data on this soon,” she adds.
In the second study, 45 patients were reviewed. All patients had been called back for a second mammogram because their first showed a possible abnormality; “30 of them were subsequently found by additional mammographic views to have breast tissue overlap accounting for their possible abnormality,” she says. Fifteen patients went on to biopsy. “We asked radiologists to look at the TOMO study (without knowing the results of the second mammogram or biopsy) and indicate whether they would have called these patients back for additional evaluation,” says Dr. Rafferty. They indicated that they would have only called back five of the 30 patients who had breast tissue overlap. “If we could have used TOMO on these patients initially, it would have saved 25 women the anxiety they felt and the inconvenience they experienced of being called back for additional tests,” notes Dr. Rafferty.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
