The largest study to date comparing film-screen and full-field digital mammography found the digital approach better for visualizing microcalcifications deemed crucial to diagnosing ductal carcinoma in situ.
The largest study to date comparing film-screen and full-field digital mammography found the digital approach better for visualizing microcalcifications deemed crucial to diagnosing ductal carcinoma in situ.
Dr. Nico Karssemeijer from Radboud University in Nijmegen, the Netherlands, and colleagues evaluated 367,600 screening exams performed over five years, 56,518 of which were digital. Breast cancer was found in 1927 women, 317 of whom underwent digital mammography enhanced with computer-aided diagnosis.
At initial screenings, digital detected cancer at a rate of 0.77% and film at a rate of 0.62%. Subsequent readings led to rates of 0.55% and 0.49%, respectively, for digital and film. Film-based screening detection of DCIS was 0.12% in initial exams and 0.08% in subsequent exams. Digital mammography DCIS detection was 0.22% in initial exams and 0.12% in subsequent exams (Radiol 2009 July 31 e-pub ahead of print).
AI-Initiated Recalls After Screening Mammography Demonstrate Higher PPV for Breast Cancer
March 18th 2025While recalls initiated by one of two reviewing radiologists after screening mammography were nearly 10 percent higher than recalls initiated by an AI software, the AI-initiated recalls had an 85 percent higher positive predictive value for breast cancer, according to a new study.
