Technologists can accurately classify screening mammograms, showing reasonable accuracy without specific training. Further exploration into trained technologists grouping mammogram cases is warranted.

Area of Science:

  • Radiology
  • Medical Imaging
  • Breast Imaging

Background:

  • Screening mammography is crucial for early breast cancer detection.
  • Accurate interpretation of mammograms is essential for timely diagnosis and treatment.
  • The role of technologists in initial mammogram classification requires investigation.

Purpose of the Study:

  • To evaluate the accuracy of technologists in classifying screening mammograms.
  • To compare technologist interpretations with radiologist assessments.
  • To determine if technologists can differentiate between negative findings and those requiring follow-up.

Main Methods:

  • A prospective study involved 33 technologists across multiple facilities.
  • 3019 mammographic examinations were reviewed by technologists.

  • Technologist interpretations were compared against radiologist diagnoses.

    • Main Results:

    • Technologists and radiologists achieved 82% agreement in mammogram classification.
    • Agreement was 77% for negative findings and 5% for follow-up recommendations.
    • Of cases flagged for follow-up by radiologists only, 17 led to biopsies, with two malignant findings.

    Conclusions:

    • Technologists demonstrate reasonable accuracy in classifying screening mammograms without specialized training.
    • The potential for trained technologists to assist in mammogram case categorization warrants further research.
    • This study highlights a potential role for technologists in streamlining mammography workflows.
