(SEATTLE) -- Radiologists in the U.S. are required by the Food and Drug Administration to interpret 960 mammograms in a two-year time span, but a new study published Tuesday in Radiology suggests that may not be enough.
The study, conducted at the Group Health Research Institute, evaluated the screening performance of 120 radiologists who interpreted almost 800,000 mammograms between 2002 and 2006. It found that radiologists who interpreted a high volume of mammograms turned out to be better “readers.”
More specifically, radiologists who read 1,500 mammograms or more per year had lower false-positive rates, meaning they sent fewer women for unnecessary follow up tests for non-cancerous abnormalities.
In light of this discovery, the study's authors concluded that "U.S. volume requirements could be increased to 1,000 or 1,5000 screening mammograms per year… which would optimize sensitivity and false positive rates."
