3D Mammography Finds More Invasive Cancers and Reduces Unnecessary Recalls, JAMA and AJR Studies Show

Dr. Julianne Greenberg of Washington Radiology Associates co-authored two 3D mammography studies, including the largest one to date with nearly half a million patients.

Washington, DC (June 24, 2014) — 3D Mammography finds significantly more invasive cancers and reduces unnecessary recalls, according to two large, retrospective studies published in The American Journal of Roentgenology (AJR) and The Journal of the American Medical Association (JAMA). The studies feature data from Washington Radiology Associates, PC (WRA) collected from its six clinical offices in the District, Chevy Chase, Bethesda, Potomassc, Fairfax and Sterling.

The studies focused on the impact of 3D mammography and demonstrate the following key findings:

AJR Key Findings: JAMA Key Findings:
  • 44% increase in invasive cancer detected with 3D mammography
  • 41% increase in invasive cancer detected with 3D mammography
  • 16% decrease in recall rate from screening mammography
  • 15% decrease in recall rate from screening mammography
  • 29% increase in the detection of all breast cancers
  • 29% increase in the detection of all breast cancers

"These studies confirm and expand upon what we already know: 3D mammography finds more of the invasive, harmful breast cancers, and saves many women the unnecessary anxiety and costs of a return for additional imaging for what turns out to be a false alarm," said Julianne Greenberg, MD. "The results from the multi-center JAMA study reinforce our own scientific findings from WRA that were recently published in the AJR.  Together, the results from these two studies are powerful indicators for the positive impact of 3D mammography on population-based breast cancer screening.” She added, “We are proud to be part of these landmark scientific studies."

In October 2011, WRA was the first to bring 3D mammography to women in DC, Maryland and northern Virginia and has offered this new technology at its six clinical offices since February 2012.  WRA physicians have performed approximately 115,000 3D mammograms to date.  The practice was the first in the area to install low-dose 3D mammography technology, and will be the first to offer the benefits of low-dose 3D with computer-aided detection (CAD) later this year. 

These studies were published in advance of print on the AJR and JAMA websites.
