Internet May Be Answer to Mammography Crisis


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: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
