Rates and Causes of Disagreement in Interpretation of Full-Field Digital Mammography and Film-Screen Mammography in a Diagnostic Setting

Abstract

Significant disagreement between film-screen mammography and digital mammography affecting follow-up management was present in only 4% of breasts. The most frequent cause of disagreement in interpretation was a difference in management approach between radiologists (interobserver variability). This source of variability was larger than that due to differences in lesion visibility between film-screen mammography and digital mammography.
