Computer-Aided Breast Cancer Detection in Women Undergoing Screening Mammography

OBJECTIVES: * Compare, prospectively, the breast cancer detection rate and recall rate of single reading using computer-aided detection vs standard double reading in women undergoing screening mammography. OUTLINE: This is a prospective, randomized, multicenter study. Participants are randomized to 1 of 3 screening arms. * Arm I (double reading): Screening mammograms are independently reviewed by two readers (i.e., radiologist or radiographer), each of whom reports on any abnormalities and decides whether a participant is recalled for further assessment or returned home to routine screening. In the event there is disagreement between the readers' findings, a third reader acts as an arbitrator by rendering an interpretation of the mammogram and making the final decision to recall the participant or return to routine screening. * Arm II (single reading with computer-aided detection \[CAD\]): Screening mammograms are reviewed initially by a single reader who reports on any abnormalities. The reader then re-examines the mammogram with the aid of CAD, a system that uses computer prompts to recall suspicious features or abnormalities that may have been overlooked or previously dismissed as being normal. Based on these evaluations, a recommendation is made by the reader to either recall the participant for further assessment or return home to routine screening. If there is a discrepancy between the reader's interpretation and the CAD findings, another reader may be consulted to review the mammogram. * Arm III (double reading followed by single reading with CAD): Screening mammograms are reviewed by double reading as in arm I followed by single reading with CAD as in arm II.
