Technology Overview DIGITAL MAMMOGRAPHY MBI Takes On FFDM Molecular breast imaging rivals FFDM for dense breasts, but will it be readily adopted? By Antonio Garcia, industry manager, Medical Imaging Group, Frost & Sullivan -ray mammography is considered the “gold standard” for breast cancer screening in the breast imaging equipment market. The procedure is generally seen as the most effective option for women needing a diagnosis of any abnormalities in the breasts. However, with recent advances in other diagnostic breast cancer tests, such as breast MRI and molecular breast imaging, mammography may slip from its golden status. X Widespread Application Mammograms aren’t necessarily the most effective but rather, the most available method for diagnosing breast cancer. While the analog segment in mammography continually declines in revenue growth – revenues are based on manufacturer revenues from sales of equipment to hospitals, private radiology practices, clinics and imaging centers – substantial growth is seen in full-field digital (FFDM) X-ray mammography, which is still a driver in this segment. Indeed, according to Frost & Sullivan’s discussions with hospital facility procurement officers, FFDM is certainly deemed a “priority” purchase in 2009. The total North American breast imaging equipment market was $910.3 million in 2007. X-ray mammography contributes to 67 percent of this figure, and is expected to maintain this healthy dominance in the total breast imaging market going forward. However, given recent trends and the results of some highly anticipated studies, mammography may at some point yield to some more sophisticated – and more accurate – methods for detection of cancers in women. CAD Could Improve Cancer Detection Rate in Mammography Researchers found that, “Single reading with computer-aided detection could be an alternative to double reading and could improve the rate of detection of cancer from screening mammograms read by a single reader,” in a recent study published in the October issue of The New England Journal of Medicine. The study was a prospective, multi-center clinical trial, comparing the cancer detection rate for single reading of screening mammograms with CAD input versus double reading without CAD support. Researchers used Hologic’s R2 computer-aided detection (CAD) system in the study. Interpretation by two readers (double reading) rather than one reader is known to improve the cancer detection rate. The study’s authors said, “Where single reading is standard practice, computer-aided detection has the potential to improve cancer detection to the level achieved by double reading.” In the study, lead author Fiona Gilbert, M.D., and her colleagues in the United Kingdom analyzed the screening results from 31,057 women undergoing routine screening by film mammography and found that a single reader with Hologic’s R2 CAD system produced comparable cancer detection rates (87.2 percent) to double reading (87.7 percent) without CAD. Although single reading with CAD produced a higher recall rate (3.9 percent) than double reading (3.4 percent), they concluded that despite this difference, “Single reading with computer-aided detection could be an alternative to double reading and could improve the rate of detection of cancer from screening mammograms read by a single reader.” “Double reading is a method for increasing cancer detection commonly used in European screening programs. However, it is used by few practices in the U.S. because it is time-consuming and because of a shortage of radiologists focused on breast imaging,” said Ronald A. Castellino, M.D., FACR, chief medical officer for Hologic. “These results indicate that in the United States, where single reading of mammograms is most common, Hologic’s R2 CAD system can provide an improvement in cancer detection rates comparable to those achieved with double reading. This important study, combined with prior published research studies, further supports the use of the R2 CAD system to increase cancer detection.” For more information: www.hologic.com MBI can detect three times as many cancers in women who have dense breast patterns. New Rivals to Mammography Duke Granted, mammography has its competition: breast magnetic resonance imaging (MRI), nuclear breast imaging and breast ultrasound. However, new promise is seen in molecular breast imaging (MBI), a new experimental method that is currently in advanced testing at the Mayo Clinic in Rochester, ® MN.
