Experienced Radiologists Can Detect Breast Cancer on Mammograms in a Split Second

Experienced Radiologists Can Detect Breast Cancer on Mammograms in a Split Second
Visual researchers at Brigham and Women's Hospital (BWH), MD Anderson Cancer Center in Texas, and the University of York and Leeds in England presented mammograms to experienced radiologists for half a second and found they could detect abnormalities in breast tissue at better than chance levels. The researchers then performed a series of experiments to test this ability to explore what signal may alert radiologists to the presence of a possible abnormality in mammograms in the hopes of using these insights to improve breast cancer screening and early detection. The study, “A half-second glimpse often lets radiologists identify breast cancer cases even when viewing the mammogram of the opposite breast,” was published in the Proceedings of the National Academy of Sciences. "Radiologists can have 'hunches' after a first look at a mammogram. We found that these hunches are based on something real in the images. It's really striking that in the blink of an eye, an expert can pick up on something about that mammogram that indicates abnormality," Jeremy Wolfe, PhD, senior author of the study and director of the Visual Attention Laboratory at BWH, said in a news release. "Not only that, but they can detect something abnormal in the other breast, the breast that does not contain a lesion." In North America, screening mammography has a false negative rate of 20 to 30 percent and a recall r
