    Radiology training emphasizes systematic image viewing, but practice reveals a discrepancy. Most radiologists use free search, not the taught bilateral comparisons, impacting diagnostic accuracy.

    Area of Science:

    • Medical imaging
    • Radiology education
    • Visual perception in medicine

    Background:

    • Current radiology education emphasizes systematic and directive image viewing techniques.
    • These techniques often involve comparing bilateral features for comprehensive analysis.
    • A gap may exist between taught methodologies and actual radiological practice.

    Purpose of the Study:

    • To investigate the discrepancy between instructed and practiced image viewing techniques in radiology.
    • To compare the teaching methods of radiology instructors and residents with the actual eye-tracking behavior of radiologists.
    • To identify potential areas for improvement in radiology education and training.

    Main Methods:

    • Surveying radiology instructors and residents regarding their teaching methods for image viewing.

  • Measuring eye activity of a separate group of radiologists while they viewed chest images.
  • Analyzing visual search patterns and the frequency of bilateral comparisons during image interpretation.

    • Main Results:

    • Taught techniques advocate for systematic, directive viewing with bilateral comparisons.
    • Actual image reading predominantly follows a free search pattern.
    • Bilateral comparisons constitute less than 4% of observed visual activity during image interpretation.

    Conclusions:

    • A significant discrepancy exists between the systematic viewing techniques taught in radiology and the free search methods practiced by radiologists.
    • This gap highlights a need to re-evaluate radiology training to align instruction with practical application.
    • Further research is warranted to understand the implications of these viewing habits on diagnostic performance.
