Disagreements in chest roentgen interpretation.

P G Herman, D E Gerson, S J Hessel

    Chest
    |September 1, 1975
    PubMed
    Summary

    Radiologist disagreement is common in chest radiograph interpretation, with significant errors and omissions frequently occurring. Improving diagnostic accuracy requires addressing false negatives and indeterminate findings in medical imaging.

    Area of Science:

    • Radiology
    • Medical Imaging Analysis
    • Diagnostic Accuracy

    Background:

    • Chest radiography is a cornerstone of thoracic disease diagnosis.
    • Variability in radiologist interpretation can impact patient care.
    • Understanding disagreement patterns is crucial for quality improvement.

    Purpose of the Study:

    • To analyze disagreement among radiologists interpreting chest radiographs.
    • To quantify the types and significance of interpretation errors.
    • To identify factors associated with diagnostic variability.

    Main Methods:

    • 100 chest radiographs with abundant abnormalities were reviewed by five experienced radiologists.
    • Disagreement analysis focused on the entire interpretation content.

  • A panel graded disagreements by type (false negative, false positive, indeterminate) and significance.

    • Main Results:

    • Overall radiologist repeatability was 75%.
    • 41% of reports had significant errors; 56% had indeterminate disagreements.
    • False negatives constituted 78% of all errors, with an average omission rate of 25% for important findings.

    Conclusions:

    • Significant inter-reader variability exists in chest radiograph interpretation.
    • False negatives are the predominant error type, highlighting a need for improved detection of abnormalities.
    • Specific abnormalities correlate with disagreement types, suggesting targeted training may be beneficial.
