WASHINGTON (CNN) -- The Food and Drug Administration Monday
approved the first mammography system that produces digital images for use in
the United States.
The Senographe 2000D is designed to generate digital mammographic images
that can be used for screening and diagnosis of breast cancer and can be used
as an alternative to traditional methods of mammography.
Clinical studies of digital mammography compared with analog or
traditional mammography were found to have "comparable clinical performance" in
screening and diagnosis of breast cancer.
The FDA said, from a patient's point of view, mammography with a digital
system "is essentially the same" as with the traditional film/screen system."
The evidence so far does not show that the digital images are more helpful in
finding cancer than the analog/film images," the FDA said. However, the FDA has
said that the digital technology offers potential advantages over standard
Digital images can be stored and transferred electronically
Digital images can be manipulated to correct for under- or overexposure
without having to take another mammogram.
Digital mammography has a large dynamic range that allows examination
of all areas of the breast that analog systems sometimes have trouble with.
"This is the single biggest advance in mammography in 30 years, and women
throughout the United States now have access to a powerful new tool in the
fight against breast cancer," said Jeff Immelt, President and CEO of GE
Medical, the manufacturer of the Senographe 2000D.
