Baseline screening mammography: one vs two views per breast.

E A Sickles, W N Weber, H B Galvin

    AJR. American Journal of Roentgenology
    |December 1, 1986
    PubMed
    Summary

    Two-view mammography screening detects more cancers and reduces the need for follow-up imaging compared to one-view screening. Baseline mammography should utilize two views per breast for improved cancer detection and efficiency.

    Area of Science:

    • Radiology
    • Oncology
    • Medical Imaging

    Background:

    • Screening mammography is crucial for early breast cancer detection.
    • Optimizing mammography protocols balances cost, radiation exposure, and diagnostic accuracy.

    Purpose of the Study:

    • To compare the diagnostic yield and efficiency of one-view versus two-view mammography for baseline screening.
    • To evaluate the impact of projection views on cancer detection rates and the need for additional imaging.

    Main Methods:

    • Retrospective review of baseline mammograms from 2500 asymptomatic women.
    • Two separate interpretations: one using mediolateral oblique (MLO) view only, the other using both MLO and craniocaudal (CC) views.
    • Comparison of cancer detection rates and recall rates between one-view and two-view interpretations.

    Main Results:

    • Two-view mammography identified more cancers (27) than one-view (25).
    • Two-view interpretations required significantly fewer additional mammograms for abnormality evaluation (642 vs 179, 26% vs 7%).
    • The advantages of two-view screening outweigh the minimal increase in radiation and cost.

    Conclusions:

    • Baseline screening mammography should be performed using two views per breast (CC and MLO).
    • Two-view mammography offers superior cancer detection and reduces unnecessary follow-up procedures.
