Perhaps the biggest thing that led to the failure of CAD in mammography was that its developers used supervised learning, which ultimately leads to decreased specificity. Sure, radiologists could compare mammograms to earlier studies-but would their equipment actually allow them to? The authors explained that CAD’s “inferior performance” also had to do with the technology’s processing power. Kohli and Jha added that radiologists tended to treat CAD like a “second reader” or “spell-checker” instead of a legitimate game-changer. Thus, CAD had both lower sensitivity and lower specificity, a nonredeeming quality for an imaging test.”

“CAD could lull the novice reader into a false sense of security. “Not only did CAD increase the recalls without improving cancer detection, but, in some cases, even decreased sensitivity by missing some cancers, particularly noncalcified lesions,” wrote authors Ajay Kohli, MD, of the Drexel University College of Medicine in Philadelphia, and Saurabh Jha, MD, with the Hospital of the University of Pennsylvania in Philadelphia. One of the biggest reasons for this was simple: CAD just wasn’t getting the job done. Though excitement about CAD’s potential was significant early on, the authors noted that it didn’t take long for radiologists to question the technology’s usefulness. So what went wrong?Īccording to a new analysis published in the Journal of the American College of Radiology, it’s important for today’s specialists to understand what led to CAD failing in mammography-there are lessons to be learned that can help artificial intelligence (AI) succeed in the years ahead. Food and Drug Administration approved computer-aided diagnosis (CAD) in mammography in 1998 and CMS approved reimbursement for CAD in 2002, there was a lot of optimism about the future of this advanced technology.
