Summary

Switching to soft-copy interpretation in ultrasound imaging increased the number of images per exam but significantly reduced imaging time. This efficiency gain improves technologist performance and allows for more patient scans daily.

Area of Science:

  • Medical Imaging
  • Diagnostic Ultrasound
  • Radiology Workflow Optimization

Background:

  • Traditional film-based interpretation in ultrasound requires specific image capture protocols.
  • Transitioning to digital soft-copy interpretation offers potential workflow and efficiency benefits.

Purpose of the Study:

  • To evaluate the impact of soft-copy interpretation on the number of ultrasound images acquired.
  • To assess changes in imaging time per sonogram after adopting soft-copy interpretation.

Main Methods:

  • A comparative study was conducted before and after soft-copy conversion.
  • 20 normal abdominal, renal, and cranial sonograms were analyzed per technologist (360 total).
  • Multivariate repeated measures analysis of variance was used to compare image counts and imaging times.

Main Results:

  • Soft-copy interpretation led to a significant increase in the number of images per sonogram (P = 0.004).
  • Imaging time per sonogram significantly decreased by an average of 19% (P < 0.001).
  • Increased image acquisition resulted in a negligible storage cost increase ($1.06 for 213 images).

Conclusions:

  • Soft-copy conversion enhances technologist efficiency in ultrasound examinations.
  • The increase in images and decrease in time suggest improved diagnostic data capture and workflow.
  • Potential for increased daily throughput and revenue generation is indicated.
