"Our early results suggest that stereo digital mammography could contribute to the earlier detection of cancer," Dr. Getty said. "A small percentage of the additional lesions missed by standard mammography but detected by stereoscopic mammography will turn out to be cancerous."
Of the 259 findings, 150 were false positives, meaning further testing revealed that no abnormality was present. Standard mammography yielded 103 false positives; stereo mammography yielded 53.
"In our study, stereo digital mammography reduced false positives by 49 percent," said Dr. Getty. "This could have a significant impact by cutting in half the number of women who are needlessly recalled for additional diagnostic work-ups, resulting in a large savings in cost and patient anxiety."
By the end of the clinical trial this December, a total of 1,500 women at elevated risk of developing breast cancer will have received both the stereo and standard digital mammography screening exams.
According to Dr. Getty, offering wide-scale stereoscopic digital mammography would entail minor changes to digital mammography equipment and software.

AT A GLANCE
-- A new mammography technology allows radiologists to detect more cancers
with fewer false positives.
-- Stereoscopic digital mammography produces three-dimensional, in-depth
