Building a Better Mammogram — in 3D

Monday, 10 Dec 2012 11:45 AM


A new three-dimensional (3D) digital mammography technique has been found to offer significant improvements over traditional breast cancer screening.
A new study on the novel technique — called stereoscopic digital mammography (SDM) — found that it overcomes the limitations of standard two-dimensional breast X-rays by mimicking the way that human eyes work together to form a 3D image, researchers reported in the journal Radiology.
As a result, SDM may offer marked benefits over the current primary screening method for early detection of breast cancer in women and give doctors the ability to identify tumors and lesions at different depths within the breast — potentially reducing both false positive findings and recalls and giving more accurate diagnoses.

"Our eyes see the world from two slightly different perspectives," said Dr. Carl J. D'Orsi, from the Department of Radiology and Imaging Sciences at Emory University School of Medicine and the Winship Cancer Institute at Emory University in Atlanta. "In this technique, the X-ray tube functions as the eyeball, with two different images providing slightly different views of the internal structure of the breast."
To reach their conclusions, D'Orsi and colleagues compared SDM to conventional mammography in 779 patients at elevated risk of developing breast cancer. Patients received both exams in a single visit, and two experienced radiologists independently interpreted the scans. The results showed SDM significantly improved the accuracy of cancer detection.
"We found that the stereoscopic technique could significantly decrease the need for calling women back for additional exams," D'Orsi said.
