Internet May Be Answer to Mammography Crisis

30.11.2005


Digital mammography images can be accurately transmitted over broadband Internet, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).



"We’ve proven that telemammography works," said the study’s lead author, Alan R. Melton, M.D., assistant clinical professor of radiology at New York Presbyterian Hospital-Columbia University Medical Center in New York City. "The ability to transmit mammograms over long distances could significantly help to solve the crisis in access to screening mammography, as well as improve the accuracy of interpretation of the examinations."

According to a 2004 report from the Institute of Medicine, women’s access to breast cancer screening is endangered due to a shortage of specialists in breast imaging and interpretation. Between 2000 and 2003, the number of mammography facilities operating in the United States dropped from 9,400 to 8,600 (an 8.5 percent decrease), causing women in some areas delays of up to five months for screening mammography services. One cause of the shortage has been the historically low level of reimbursement for mammography interpretation and the high level of medico-legal risk.


Dr. Melton’s study, which included 1,314 diagnostic screening mammograms, determined that it is possible to transmit full-field digital mammography (FFDM) images to another location for interpretation without compromising accuracy, security or the use of computer-aided detection software.

In his study, Dr. Melton used two FFDM units and a computer-aided detection (CAD) system. The digital images were transmitted via Internet cable in a highly secure environment, including private networks and firewalls, to an interpreting workstation 110 miles away. Each image was transmitted in less than 45 seconds.

Through a series of tests, the researchers determined that digital mammograms sent to the remote workstation were identical to the original images. The analysis included comparison of image quality, file sizes, CAD markings and image interpretation by an independent reader.

"These results suggest that regional interpretation centers could be established to improve the accuracy and efficiency of screening mammography, reduce screening backlogs and aid underserved areas," Dr. Melton said. He envisions reconfiguring the way mammograms are interpreted by creating regional Centers of Excellence, where highly skilled radiologists would read digital mammograms transmitted from multiple centers.

"Finding more breast cancers earlier, which I believe we can do through digital mammography and Centers of Excellence, will significantly reduce the number of women dying from breast cancer," he said.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
