  1. Findings at mammographic screening on only one standard projection : Outcomes analysis.

    Article - En anglais

    PURPOSE 

    To determine the radiographic and clinical outcomes of findings seen at mammographic screening on only one standard projection.

    MATERIALS AND METHODS 

    To identify prospectively marked benign-appearing and abnormal findings that were seen on only one standard projection, 63,836 consecutive two-view mammographic screening studies were reviewed.

    Subsequent outcomes analysis included determination of the frequency of occurrence, mammographic features, work-up performed, and final imaging assessment.

    For imaging findings that prompted tissue sampling, histopathologic diagnosis was recorded.

    To identify breast cancers among the remaining findings, screening cases were linked with a regional tumor registry.

    RESULTS 

    Of the 61,273 screening studies available for review, 2,023 (3.3%) involved prospectively identified findings seen on only one standard projection.

    One thousand eighty-six (53.7%) studies with one-view-only findings were judged to represent superimposition of normal breast structures (summation artifact) simply from the standard projections obtained at screening ; findings in an additional 587 (29.0%) studies were characterized as representing superimposition of normal structures after recall for further diagnostic imaging.

    None of these 1,673 cases was subsequently found to be cancer. (...)
