Implementing continuous image quality assurance and control programs significantly reduces reject rates in medical imaging. Consistent monitoring and procedural adjustments are key to achieving favorable and economically justifiable results.

Area of Science:

  • Medical Imaging Technology
  • Radiology Quality Control

Background:

  • A sustained image quality assurance and control program has been operational for over nine years.
  • Reject-repeat analyses have been a primary tool for assessing image quality.

Purpose of the Study:

  • To evaluate the effectiveness of a long-term image quality assurance and control program.
  • To analyze trends in reject rates and identify factors influencing them.

Main Methods:

  • Conducting reject-repeat analyses nine times over the program's duration.
  • Monitoring reject rates before and after departmental relocation and equipment changes.
  • Implementing revised procedures including equipment calibration and staff education.

Main Results:

  • Initial reject rate of 15% decreased to 8.4% in 1982.
  • Rate increased to 13.2% after relocation and equipment changes.
  • Revised procedures led to significant reductions, reaching 6.4% in 1988.

Conclusions:

  • Continuous image quality assurance and control are essential for sustained improvements.
  • Programmatic adjustments, including technical control and education, are vital for maintaining low reject rates.
  • Ongoing quality management yields favorable and economically justifiable outcomes in medical imaging.
