Screening breast ultrasound detects cancers missed on mammography in women with dense breasts

18.04.2013
Screening breast ultrasound performed after mammography on women with greater than 50% breast density detects an additional 3.4 cancers or high risk lesions per one thousand woman screened, a detection rate just under that of screening mammography alone for women with less dense breasts, a new study shows. Screening mammography detects 4-5 cancers per thousand women screened.

The study, conducted in conjunction with seven Connecticut radiology practices, included 19,745 women who had dense breasts and "normal" mammograms. Sixty-seven cancers were found, said Dr. Sarah Steenbergen, lead author of the study, who is now at Yale University in New Haven, CT.

"Out of the available surgical reports, only one case had nodal involvement at the time of diagnosis. This suggests that the cancers are detected early and therefore we anticipate a survival benefit," Dr. Steenbergen said.

The study has been conducted over two years, "and we've seen an improvement in the sensitivity of screening breast ultrasound from 96.6% to 100% and in specificity from 94.0% to 96% from the first to the second year," she said.
This illustrates a learning curve, and "we anticipate that as the number of screening breast ultrasounds increase, physicians will be even better able to differentiate benign from malignant lesions," she said.

Recent legislation in Connecticut mandates reporting of breast density on mammograms and recommending follow up screening ultrasound for women with greater than 50% breast density, said Dr. Steenbergen.
The study was conducted, in part, to measure the outcome of this legislation and what we can hope to achieve with screening breast ultrasound, she said.

Dr. Steenbergen will present her study at the ARRS annual meeting on April 18 in Washington, DC.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
