Page: << Prev | 1 | 2 Double reading found 87.7 percent of the cancers, while CAD plus a single reading was able to detect 87.2 percent. Recall rates, that is the number of women called back for further testing due to suspicious findings, were 3.4 percent for double reading and 3.9 percent for single reading with CAD.
The study findings were expected to be published in the Oct. 16 issue of the New England Journal of Medicine, but were posted online Oct. 1.
"CAD could increase the cancer detection rate of a single reader in breast screening centers currently using single reading alone," said Gilbert, who added that, "in countries where double reading is standard practice, CAD could be used if there is a shortage of readers without compromising cancer detection rates."

Hall said it's likely that, if this study had been done with a digital mammography system, the results would have been even better. He said for this study, the researchers took mammography films and scanned them into the computer before the computer reading. That means the computer was essentially checking a copy, and when you copy something, information may be lost, he said.
"There are definite advantages to digital mammography with CAD. Digital helps you visualize the anatomy better, and the CAD helps keep you on your toes," Hall said.
